Supabase MCP Server

Query | MCP server for Supabase

🌅 More than 17k installs via pypi and close to 30k downloads on Smithery.ai — in short, this was fun! 🥳 Thanks to everyone who has been using this server for the past few months, and I hope it was useful for you. Since Supabase has released their own official MCP server, I've decided to no longer actively maintain this one. The official MCP server is as feature-rich, and many more features will be added in the future. Check it out!

Getting Started

Prerequisites

Installing the server requires the following on your system:

  • Python 3.12+

If you plan to install via uv, ensure it's installed.

PostgreSQL Installation

PostgreSQL installation is no longer required for the MCP server itself, as it now uses asyncpg which doesn't depend on PostgreSQL development libraries.

However, you'll still need PostgreSQL if you're running a local Supabase instance:

MacOS

brew install postgresql@16

Windows

Step 1. Installation

Since v0.2.0 I introduced support for package installation. You can use your favorite Python package manager to install the server via:

# if pipx is installed (recommended)
pipx install supabase-mcp-server

# if uv is installed
uv pip install supabase-mcp-server

pipx is recommended because it creates isolated environments for each package.

You can also install the server manually by cloning the repository and running pipx install -e . from the root directory.

Installing from source

If you would like to install from source, for example for local development:

uv venv
# On Mac
source .venv/bin/activate
# On Windows
.venv\Scripts\activate
# Install package in editable mode
uv pip install -e .

Installing via Smithery.ai

You can find the full instructions on how to use Smithery.ai to connect to this MCP server here.

Step 2. Configuration

The Supabase MCP server requires configuration to connect to your Supabase database, access the Management API, and use the Auth Admin SDK. This section explains all available configuration options and how to set them up.

🔑 Important: Since v0.4 MCP server requires an API key which you can get for free at thequery.dev to use this MCP server.

Environment Variables

The server uses the following environment variables:

Variable

Required

Default

Description

SUPABASE_PROJECT_REF

Yes

127.0.0.1:54322

Your Supabase project reference ID (or local host:port)

SUPABASE_DB_PASSWORD

Yes

postgres

Your database password

SUPABASE_REGION

Yes*

us-east-1

AWS region where your Supabase project is hosted

SUPABASE_ACCESS_TOKEN

No

None

Personal access token for Supabase Management API

SUPABASE_SERVICE_ROLE_KEY

No

None

Service role key for Auth Admin SDK

QUERY_API_KEY

Yes

None

API key from thequery.dev (required for all operations)

Note: The default values are configured for local Supabase development. For remote Supabase projects, you must provide your own values for SUPABASE_PROJECT_REF and SUPABASE_DB_PASSWORD.

🚨 CRITICAL CONFIGURATION NOTE: For remote Supabase projects, you MUST specify the correct region where your project is hosted using SUPABASE_REGION. If you encounter a "Tenant or user not found" error, this is almost certainly because your region setting doesn't match your project's actual region. You can find your project's region in the Supabase dashboard under Project Settings.

Connection Types

Database Connection
  • The server connects to your Supabase PostgreSQL database using the transaction pooler endpoint

  • Local development uses a direct connection to 127.0.0.1:54322

  • Remote projects use the format: postgresql://postgres.[project_ref]:[password]@aws-0-[region].pooler.supabase.com:6543/postgres

⚠️ Important: Session pooling connections are not supported. The server exclusively uses transaction pooling for better compatibility with the MCP server architecture.

Management API Connection
  • Requires SUPABASE_ACCESS_TOKEN to be set

  • Connects to the Supabase Management API at https://api.supabase.com

  • Only works with remote Supabase projects (not local development)

Auth Admin SDK Connection
  • Requires SUPABASE_SERVICE_ROLE_KEY to be set

  • For local development, connects to http://127.0.0.1:54321

  • For remote projects, connects to https://[project_ref].supabase.co

Configuration Methods

The server looks for configuration in this order (highest to lowest priority):

  1. Environment Variables: Values set directly in your environment

  2. Local .env File: A .env file in your current working directory (only works when running from source)

  3. Global Config File:

    • Windows: %APPDATA%\supabase-mcp\.env

    • macOS/Linux: ~/.config/supabase-mcp/.env

  4. Default Settings: Local development defaults (if no other config is found)

⚠️ Important: When using the package installed via pipx or uv, local .env files in your project directory are not detected. You must use either environment variables or the global config file.

Setting Up Configuration

Set environment variables directly in your MCP client configuration (see client-specific setup instructions in Step 3). Most MCP clients support this approach, which keeps your configuration with your client settings.

Option 2: Global Configuration

Create a global .env configuration file that will be used for all MCP server instances:

# Create config directory
# On macOS/Linux
mkdir -p ~/.config/supabase-mcp
# On Windows (PowerShell)
mkdir -Force "$env:APPDATA\supabase-mcp"

# Create and edit .env file
# On macOS/Linux
nano ~/.config/supabase-mcp/.env
# On Windows (PowerShell)
notepad "$env:APPDATA\supabase-mcp\.env"

Add your configuration values to the file:

QUERY_API_KEY=your-api-key
SUPABASE_PROJECT_REF=your-project-ref
SUPABASE_DB_PASSWORD=your-db-password
SUPABASE_REGION=us-east-1
SUPABASE_ACCESS_TOKEN=your-access-token
SUPABASE_SERVICE_ROLE_KEY=your-service-role-key
Option 3: Project-Specific Configuration (Source Installation Only)

If you're running the server from source (not via package), you can create a .env file in your project directory with the same format as above.

Finding Your Supabase Project Information

  • Project Reference: Found in your Supabase project URL: https://supabase.com/dashboard/project/<project-ref>

  • Database Password: Set during project creation or found in Project Settings → Database

  • Access Token: Generate at https://supabase.com/dashboard/account/tokens

  • Service Role Key: Found in Project Settings → API → Project API keys

Supported Regions

The server supports all Supabase regions:

  • us-west-1 - West US (North California)

  • us-east-1 - East US (North Virginia) - default

  • us-east-2 - East US (Ohio)

  • ca-central-1 - Canada (Central)

  • eu-west-1 - West EU (Ireland)

  • eu-west-2 - West Europe (London)

  • eu-west-3 - West EU (Paris)

  • eu-central-1 - Central EU (Frankfurt)

  • eu-central-2 - Central Europe (Zurich)

  • eu-north-1 - North EU (Stockholm)

  • ap-south-1 - South Asia (Mumbai)

  • ap-southeast-1 - Southeast Asia (Singapore)

  • ap-northeast-1 - Northeast Asia (Tokyo)

  • ap-northeast-2 - Northeast Asia (Seoul)

  • ap-southeast-2 - Oceania (Sydney)

  • sa-east-1 - South America (São Paulo)

Limitations

  • No Self-Hosted Support: The server only supports official Supabase.com hosted projects and local development

  • No Connection String Support: Custom connection strings are not supported

  • No Session Pooling: Only transaction pooling is supported for database connections

  • API and SDK Features: Management API and Auth Admin SDK features only work with remote Supabase projects, not local development

Step 3. Usage

In general, any MCP client that supports stdio protocol should work with this MCP server. This server was explicitly tested to work with:

  • Cursor

  • Windsurf

  • Cline

  • Claude Desktop

Additionally, you can also use smithery.ai to install this server a number of clients, including the ones above.

Follow the guides below to install this MCP server in your client.

Cursor

Go to Settings -> Features -> MCP Servers and add a new server with this configuration:

# can be set to any name
name: supabase
type: command
# if you installed with pipx
command: supabase-mcp-server
# if you installed with uv
command: uv run supabase-mcp-server
# if the above doesn't work, use the full path (recommended)
command: /full/path/to/supabase-mcp-server  # Find with 'which supabase-mcp-server' (macOS/Linux) or 'where supabase-mcp-server' (Windows)

If configuration is correct, you should see a green dot indicator and the number of tools exposed by the server. How successful Cursor config looks like

Windsurf

Go to Cascade -> Click on the hammer icon -> Configure -> Fill in the configuration:

{
    "mcpServers": {
      "supabase": {
        "command": "/Users/username/.local/bin/supabase-mcp-server",  // update path
        "env": {
          "QUERY_API_KEY": "your-api-key",  // Required - get your API key at thequery.dev
          "SUPABASE_PROJECT_REF": "your-project-ref",
          "SUPABASE_DB_PASSWORD": "your-db-password",
          "SUPABASE_REGION": "us-east-1",  // optional, defaults to us-east-1
          "SUPABASE_ACCESS_TOKEN": "your-access-token",  // optional, for management API
          "SUPABASE_SERVICE_ROLE_KEY": "your-service-role-key"  // optional, for Auth Admin SDK
        }
      }
    }
}

If configuration is correct, you should see green dot indicator and clickable supabase server in the list of available servers.

How successful Windsurf config looks like

Claude Desktop

Claude Desktop also supports MCP servers through a JSON configuration. Follow these steps to set up the Supabase MCP server:

  1. Find the full path to the executable (this step is critical):

    # On macOS/Linux
    which supabase-mcp-server
    
    # On Windows
    where supabase-mcp-server

    Copy the full path that is returned (e.g., /Users/username/.local/bin/supabase-mcp-server).

  2. Configure the MCP server in Claude Desktop:

    • Open Claude Desktop

    • Go to Settings → Developer -> Edit Config MCP Servers

    • Add a new configuration with the following JSON:

    {
      "mcpServers": {
        "supabase": {
          "command": "/full/path/to/supabase-mcp-server",  // Replace with the actual path from step 1
          "env": {
            "QUERY_API_KEY": "your-api-key",  // Required - get your API key at thequery.dev
            "SUPABASE_PROJECT_REF": "your-project-ref",
            "SUPABASE_DB_PASSWORD": "your-db-password",
            "SUPABASE_REGION": "us-east-1",  // optional, defaults to us-east-1
            "SUPABASE_ACCESS_TOKEN": "your-access-token",  // optional, for management API
            "SUPABASE_SERVICE_ROLE_KEY": "your-service-role-key"  // optional, for Auth Admin SDK
          }
        }
      }
    }

⚠️ Important: Unlike Windsurf and Cursor, Claude Desktop requires the full absolute path to the executable. Using just the command name (supabase-mcp-server) will result in a "spawn ENOENT" error.

If configuration is correct, you should see the Supabase MCP server listed as available in Claude Desktop.

How successful Windsurf config looks like

Cline

Cline also supports MCP servers through a similar JSON configuration. Follow these steps to set up the Supabase MCP server:

  1. Find the full path to the executable (this step is critical):

    # On macOS/Linux
    which supabase-mcp-server
    
    # On Windows
    where supabase-mcp-server

    Copy the full path that is returned (e.g., /Users/username/.local/bin/supabase-mcp-server).

  2. Configure the MCP server in Cline:

    • Open Cline in VS Code

    • Click on the "MCP Servers" tab in the Cline sidebar

    • Click "Configure MCP Servers"

    • This will open the cline_mcp_settings.json file

    • Add the following configuration:

    {
      "mcpServers": {
        "supabase": {
          "command": "/full/path/to/supabase-mcp-server",  // Replace with the actual path from step 1
          "env": {
            "QUERY_API_KEY": "your-api-key",  // Required - get your API key at thequery.dev
            "SUPABASE_PROJECT_REF": "your-project-ref",
            "SUPABASE_DB_PASSWORD": "your-db-password",
            "SUPABASE_REGION": "us-east-1",  // optional, defaults to us-east-1
            "SUPABASE_ACCESS_TOKEN": "your-access-token",  // optional, for management API
            "SUPABASE_SERVICE_ROLE_KEY": "your-service-role-key"  // optional, for Auth Admin SDK
          }
        }
      }
    }

If configuration is correct, you should see a green indicator next to the Supabase MCP server in the Cline MCP Servers list, and a message confirming "supabase MCP server connected" at the bottom of the panel.

Troubleshooting

Here are some tips & tricks that might help you:

  • Debug installation - run supabase-mcp-server directly from the terminal to see if it works. If it doesn't, there might be an issue with the installation.

  • MCP Server configuration - if the above step works, it means the server is installed and configured correctly. As long as you provided the right command, IDE should be able to connect. Make sure to provide the right path to the server executable.

  • "No tools found" error - If you see "Client closed - no tools available" in Cursor despite the package being installed:

    • Find the full path to the executable by running which supabase-mcp-server (macOS/Linux) or where supabase-mcp-server (Windows)

    • Use the full path in your MCP server configuration instead of just supabase-mcp-server

    • For example: /Users/username/.local/bin/supabase-mcp-server or C:\Users\username\.local\bin\supabase-mcp-server.exe

  • Environment variables - to connect to the right database, make sure you either set env variables in mcp_config.json or in .env file placed in a global config directory (~/.config/supabase-mcp/.env on macOS/Linux or %APPDATA%\supabase-mcp\.env on Windows).

  • Accessing logs - The MCP server writes detailed logs to a file:

    • Log file location:

      • macOS/Linux: ~/.local/share/supabase-mcp/mcp_server.log

      • Windows: %USERPROFILE%\.local\share\supabase-mcp\mcp_server.log

    • Logs include connection status, configuration details, and operation results

    • View logs using any text editor or terminal commands:

      # On macOS/Linux
      cat ~/.local/share/supabase-mcp/mcp_server.log
      
      # On Windows (PowerShell)
      Get-Content "$env:USERPROFILE\.local\share\supabase-mcp\mcp_server.log"

If you are stuck or any of the instructions above are incorrect, please raise an issue.

MCP Inspector

A super useful tool to help debug MCP server issues is MCP Inspector. If you installed from source, you can run supabase-mcp-inspector from the project repo and it will run the inspector instance. Coupled with logs this will give you complete overview over what's happening in the server.

📝 Running supabase-mcp-inspector, if installed from package, doesn't work properly - I will validate and fix in the coming release.

Feature Overview

Database query tools

Since v0.3+ server provides comprehensive database management capabilities with built-in safety controls:

  • SQL Query Execution: Execute PostgreSQL queries with risk assessment

    • Three-tier safety system:

      • safe: Read-only operations (SELECT) - always allowed

      • write: Data modifications (INSERT, UPDATE, DELETE) - require unsafe mode

      • destructive: Schema changes (DROP, CREATE) - require unsafe mode + confirmation

  • SQL Parsing and Validation:

    • Uses PostgreSQL's parser (pglast) for accurate analysis and provides clear feedback on safety requirements

  • Automatic Migration Versioning:

    • Database-altering operations operations are automatically versioned

    • Generates descriptive names based on operation type and target

  • Safety Controls:

    • Default SAFE mode allows only read-only operations

    • All statements run in transaction mode via asyncpg

    • 2-step confirmation for high-risk operations

  • Available Tools:

    • get_schemas: Lists schemas with sizes and table counts

    • get_tables: Lists tables, foreign tables, and views with metadata

    • get_table_schema: Gets detailed table structure (columns, keys, relationships)

    • execute_postgresql: Executes SQL statements against your database

    • confirm_destructive_operation: Executes high-risk operations after confirmation

    • retrieve_migrations: Gets migrations with filtering and pagination options

    • live_dangerously: Toggles between safe and unsafe modes

Management API tools

Since v0.3.0 server provides secure access to the Supabase Management API with built-in safety controls:

  • Available Tools:

    • send_management_api_request: Sends arbitrary requests to Supabase Management API with auto-injection of project ref

    • get_management_api_spec: Gets the enriched API specification with safety information

      • Supports multiple query modes: by domain, by specific path/method, or all paths

      • Includes risk assessment information for each endpoint

      • Provides detailed parameter requirements and response formats

      • Helps LLMs understand the full capabilities of the Supabase Management API

    • get_management_api_safety_rules: Gets all safety rules with human-readable explanations

    • live_dangerously: Toggles between safe and unsafe operation modes

  • Safety Controls:

    • Uses the same safety manager as database operations for consistent risk management

    • Operations categorized by risk level:

      • safe: Read-only operations (GET) - always allowed

      • unsafe: State-changing operations (POST, PUT, PATCH, DELETE) - require unsafe mode

      • blocked: Destructive operations (delete project, etc.) - never allowed

    • Default safe mode prevents accidental state changes

    • Path-based pattern matching for precise safety rules

Note: Management API tools only work with remote Supabase instances and are not compatible with local Supabase development setups.

Auth Admin tools

I was planning to add support for Python SDK methods to the MCP server. Upon consideration I decided to only add support for Auth admin methods as I often found myself manually creating test users which was prone to errors and time consuming. Now I can just ask Cursor to create a test user and it will be done seamlessly. Check out the full Auth Admin SDK method docs to know what it can do.

Since v0.3.6 server supports direct access to Supabase Auth Admin methods via Python SDK:

  • Includes the following tools:

    • get_auth_admin_methods_spec to retrieve documentation for all available Auth Admin methods

    • call_auth_admin_method to directly invoke Auth Admin methods with proper parameter handling

  • Supported methods:

    • get_user_by_id: Retrieve a user by their ID

    • list_users: List all users with pagination

    • create_user: Create a new user

    • delete_user: Delete a user by their ID

    • invite_user_by_email: Send an invite link to a user's email

    • generate_link: Generate an email link for various authentication purposes

    • update_user_by_id: Update user attributes by ID

    • delete_factor: Delete a factor on a user (currently not implemented in SDK)

Why use Auth Admin SDK instead of raw SQL queries?

The Auth Admin SDK provides several key advantages over direct SQL manipulation:

  • Functionality: Enables operations not possible with SQL alone (invites, magic links, MFA)

  • Accuracy: More reliable then creating and executing raw SQL queries on auth schemas

  • Simplicity: Offers clear methods with proper validation and error handling

    • Response format:

      • All methods return structured Python objects instead of raw dictionaries

      • Object attributes can be accessed using dot notation (e.g., user.id instead of user["id"])

    • Edge cases and limitations:

      • UUID validation: Many methods require valid UUID format for user IDs and will return specific validation errors

      • Email configuration: Methods like invite_user_by_email and generate_link require email sending to be configured in your Supabase project

      • Link types: When generating links, different link types have different requirements:

        • signup links don't require the user to exist

        • magiclink and recovery links require the user to already exist in the system

      • Error handling: The server provides detailed error messages from the Supabase API, which may differ from the dashboard interface

      • Method availability: Some methods like delete_factor are exposed in the API but not fully implemented in the SDK

Logs & Analytics

The server provides access to Supabase logs and analytics data, making it easier to monitor and troubleshoot your applications:

  • Available Tool: retrieve_logs - Access logs from any Supabase service

  • Log Collections:

    • postgres: Database server logs

    • api_gateway: API gateway requests

    • auth: Authentication events

    • postgrest: RESTful API service logs

    • pooler: Connection pooling logs

    • storage: Object storage operations

    • realtime: WebSocket subscription logs

    • edge_functions: Serverless function executions

    • cron: Scheduled job logs

    • pgbouncer: Connection pooler logs

  • Features: Filter by time, search text, apply field filters, or use custom SQL queries

Simplifies debugging across your Supabase stack without switching between interfaces or writing complex queries.

Automatic Versioning of Database Changes

"With great power comes great responsibility." While execute_postgresql tool coupled with aptly named live_dangerously tool provide a powerful and simple way to manage your Supabase database, it also means that dropping a table or modifying one is one chat message away. In order to reduce the risk of irreversible changes, since v0.3.8 the server supports:

  • automatic creation of migration scripts for all write & destructive sql operations executed on the database

  • improved safety mode of query execution, in which all queries are categorized in:

    • safe type: always allowed. Includes all read-only ops.

    • writetype: requires write mode to be enabled by the user.

    • destructive type: requires write mode to be enabled by the user AND a 2-step confirmation of query execution for clients that do not execute tools automatically.

Universal Safety Mode

Since v0.3.8 Safety Mode has been standardized across all services (database, API, SDK) using a universal safety manager. This provides consistent risk management and a unified interface for controlling safety settings across the entire MCP server.

All operations (SQL queries, API requests, SDK methods) are categorized into risk levels:

  • Low risk: Read-only operations that don't modify data or structure (SELECT queries, GET API requests)

  • Medium risk: Write operations that modify data but not structure (INSERT/UPDATE/DELETE, most POST/PUT API requests)

  • High risk: Destructive operations that modify database structure or could cause data loss (DROP/TRUNCATE, DELETE API endpoints)

  • Extreme risk: Operations with severe consequences that are blocked entirely (deleting projects)

Safety controls are applied based on risk level:

  • Low risk operations are always allowed

  • Medium risk operations require unsafe mode to be enabled

  • High risk operations require unsafe mode AND explicit confirmation

  • Extreme risk operations are never allowed

How confirmation flow works

Any high-risk operations (be it a postgresql or api request) will be blocked even in unsafe mode. Every high-risk operation is blocked You will have to confirm and approve every high-risk operation explicitly in order for it to be executed. Explicit approval is always required

TDQS

A4.5/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes key traits: it's a 'safe, validated interface' that validates parameters against Pydantic models and rejects extra fields. It mentions that 'some methods may have nested parameter structures' and provides examples of destructive operations (delete_user, delete_factor). However, it doesn't cover rate limits, authentication requirements, or error handling.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is appropriately front-loaded with the core purpose and key capabilities, but it includes extensive lists and examples that could be streamlined. The 'AVAILABLE METHODS' section and multiple examples add value but make the description lengthy. Every sentence earns its place, but the structure could be more concise by integrating examples more tightly or referencing external documentation earlier.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity (2 parameters with nested objects, no output schema, no annotations), the description is largely complete. It covers purpose, usage, behavioral traits, and parameter semantics thoroughly. However, it lacks details on return values (since no output schema exists) and doesn't mention authentication or error scenarios. The reference to 'get_auth_admin_methods_spec' for full documentation helps mitigate gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 0% description coverage and only defines 'method' (string) and 'params' (object) without semantic details. The description compensates fully by listing all available methods with brief explanations (e.g., 'get_user_by_id: Retrieve a user by their ID'), providing detailed examples with parameter structures, and explaining that parameters must adhere to Python SDK specifications. This adds substantial meaning beyond the minimal schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Call an Auth Admin method from Supabase Python SDK' with a specific verb ('call') and resource ('Auth Admin method'). It distinguishes from siblings like 'get_auth_admin_methods_spec' (which retrieves documentation) and 'send_management_api_request' (which handles different API types). The bullet points further clarify capabilities like user management and authentication tasks.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit guidance on when to use this tool vs alternatives. It states to 'use the get_auth_admin_methods_spec tool' for complete documentation of methods and parameters, distinguishing it from that sibling. The 'IMPORTANT NOTES' section also outlines prerequisites like adhering to Python SDK specifications and validation rules, though it doesn't explicitly mention when not to use it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

confirm_destructive_operationA

Execute a destructive database or API operation after confirmation. Use this only after reviewing the risks with the user.

HOW IT WORKS:

  • This tool executes a previously rejected high-risk operation using its confirmation ID

  • The operation will be exactly the same as the one that generated the ID

  • No need to retype the query or api request params - the system remembers it

STEPS:

  1. Explain the risks to the user and get their approval

  2. Use this tool with the confirmation ID from the error message

  3. The original query will be executed as-is

PARAMETERS:

  • operation_type: Type of operation ("api" or "database")

  • confirmation_id: The ID provided in the error message (required)

  • user_confirmation: Set to true to confirm execution (default: false)

NOTE: Confirmation IDs expire after 5 minutes for security

ParametersJSON Schema

confirmation_idYes
operation_typeYes
user_confirmationNo

A4.5/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes key traits: it's for executing high-risk operations, requires user confirmation, uses a confirmation ID from a previous error, executes the original query as-is, and includes a security note about 5-minute expiration. However, it doesn't detail potential side effects (e.g., data loss specifics) or error handling, leaving some gaps in full transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (HOW IT WORKS, STEPS, PARAMETERS, NOTE), making it easy to scan. Each sentence adds value, such as explaining the confirmation process and security constraints. It could be slightly more concise by integrating some details (e.g., merging the STEPS and PARAMETERS sections), but overall, it's efficient and front-loaded with the core purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (destructive operations, confirmation flow) and lack of annotations or output schema, the description does a good job of covering essential context: purpose, usage steps, parameters, and security notes. It addresses the high-risk nature and user interaction requirements. However, it doesn't specify what happens after execution (e.g., success/failure responses or side effects), which is a minor gap for such a critical tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. It adds meaningful context for all three parameters: 'operation_type' is explained as 'Type of operation ("api" or "database")', 'confirmation_id' as 'The ID provided in the error message (required)', and 'user_confirmation' as 'Set to true to confirm execution (default: false)'. This goes beyond the schema's basic titles and enums, clarifying usage and requirements. A point is deducted because it doesn't elaborate on the implications of each operation_type choice.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Execute a destructive database or API operation after confirmation.' It specifies the verb ('execute'), resource ('destructive database or API operation'), and the key condition ('after confirmation'). The title 'confirm_destructive_operation' reinforces this, and it distinguishes itself from siblings like 'live_dangerously' or 'execute_postgresql' by focusing on confirmation of previously rejected high-risk operations.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit guidance on when to use this tool: 'Use this only after reviewing the risks with the user.' It outlines a clear process (explain risks, get approval, use confirmation ID) and specifies prerequisites (confirmation ID from an error message). It also distinguishes usage from alternatives by noting that no retyping of queries is needed, which sets it apart from tools like 'execute_postgresql' or 'send_management_api_request' that might require full parameter input.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

execute_postgresqlA

Execute PostgreSQL statements against your Supabase database.

IMPORTANT: All SQL statements must end with a semicolon (;).

OPERATION TYPES AND REQUIREMENTS:

  1. READ Operations (SELECT, EXPLAIN, etc.):

    • Can be executed directly without special requirements

    • Example: SELECT * FROM public.users LIMIT 10;

  2. WRITE Operations (INSERT, UPDATE, DELETE):

    • Require UNSAFE mode (use live_dangerously('database', True) first)

    • Example: INSERT INTO public.users (email) VALUES ('user@example.com');

  3. SCHEMA Operations (CREATE, ALTER, DROP):

    • Require UNSAFE mode (use live_dangerously('database', True) first)

    • Destructive operations (DROP, TRUNCATE) require additional confirmation

    • Example: CREATE TABLE public.test_table (id SERIAL PRIMARY KEY, name TEXT);

MIGRATION HANDLING: All queries that modify the database will be automatically version controlled by the server. You can provide optional migration name, if you want to name the migration.

  • Respect the following format: verb_noun_detail. Be descriptive and concise.

  • Examples:

    • create_users_table

    • add_email_to_profiles

    • enable_rls_on_users

  • If you don't provide a migration name, the server will generate one based on the SQL statement

  • The system will sanitize your provided name to ensure compatibility with database systems

  • Migration names are prefixed with a timestamp in the format YYYYMMDDHHMMSS

SAFETY SYSTEM: Operations are categorized by risk level:

  • LOW RISK: Read operations (SELECT, EXPLAIN) - allowed in SAFE mode

  • MEDIUM RISK: Write operations (INSERT, UPDATE, DELETE) - require UNSAFE mode

  • HIGH RISK: Schema operations (CREATE, ALTER) - require UNSAFE mode

  • EXTREME RISK: Destructive operations (DROP, TRUNCATE) - require UNSAFE mode and confirmation

TRANSACTION HANDLING:

  • DO NOT use transaction control statements (BEGIN, COMMIT, ROLLBACK)

  • The database client automatically wraps queries in transactions

  • The SQL validator will reject queries containing transaction control statements

  • This ensures atomicity and provides rollback capability for data modifications

MULTIPLE STATEMENTS:

  • You can send multiple SQL statements in a single query

  • Each statement will be executed in order within the same transaction

  • Example: CREATE TABLE public.test_table (id SERIAL PRIMARY KEY, name TEXT); INSERT INTO public.test_table (name) VALUES ('test');

CONFIRMATION FLOW FOR HIGH-RISK OPERATIONS:

  • High-risk operations (DROP TABLE, TRUNCATE, etc.) will be rejected with a confirmation ID

  • The error message will explain what happened and provide a confirmation ID

  • Review the risks with the user before proceeding

  • Use the confirm_destructive_operation tool with the provided ID to execute the operation

IMPORTANT GUIDELINES:

  • The database client starts in SAFE mode by default for safety

  • Only enable UNSAFE mode when you need to modify data or schema

  • Never mix READ and WRITE operations in the same transaction

  • For destructive operations, be prepared to confirm with the confirm_destructive_operation tool

WHEN TO USE OTHER TOOLS INSTEAD:

  • For Auth operations (users, authentication, etc.): Use call_auth_admin_method instead of direct SQL The Auth Admin SDK provides safer, validated methods for user management

  • For project configuration, functions, storage, etc.: Use send_management_api_request The Management API handles Supabase platform features that aren't directly in the database

Note: This tool operates on the PostgreSQL database only. API operations use separate safety controls.

A4.7/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure and does so comprehensively. It details safety modes (SAFE/UNSAFE), risk categorization (LOW/MEDIUM/HIGH/EXTREME), transaction handling restrictions, migration version control, confirmation flows for destructive operations, and important operational guidelines. This provides rich behavioral context beyond basic functionality.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (OPERATION TYPES, MIGRATION HANDLING, SAFETY SYSTEM, etc.) but is quite lengthy. While most content is valuable, some redundancy exists (e.g., multiple mentions of UNSAFE mode requirements). The front-loading is good with purpose and immediate requirements, but the length may challenge quick comprehension.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity of a database execution tool with 2 parameters, no annotations, and no output schema, the description provides exceptional completeness. It covers purpose, usage guidelines, behavioral traits, parameter semantics, safety systems, transaction handling, migration control, confirmation flows, and sibling tool relationships. This fully compensates for the lack of structured metadata.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage for the 2 parameters, the description compensates well by explaining both parameters' semantics. It describes 'migration_name' in detail (format requirements, examples, what happens if not provided, sanitization, timestamp prefixing) and 'query' through extensive examples and requirements (semicolon termination, operation types). While comprehensive, it doesn't explicitly map all schema properties like the default value for migration_name.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Execute PostgreSQL statements against your Supabase database.' It specifies the exact action (execute) and resource (PostgreSQL statements/Supabase database), distinguishing it from sibling tools like call_auth_admin_method or send_management_api_request that handle different aspects of the system.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit guidance on when to use this tool versus alternatives. It includes a dedicated section 'WHEN TO USE OTHER TOOLS INSTEAD' that names specific sibling tools (call_auth_admin_method, send_management_api_request) and explains what operations they handle instead. It also provides detailed context about different operation types and their requirements.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_auth_admin_methods_specA

Get Python SDK methods specification for Auth Admin.

Returns a comprehensive dictionary of all Auth Admin methods available in the Supabase Python SDK, including:

  • Method names and descriptions

  • Required and optional parameters for each method

  • Parameter types and constraints

  • Return value information

This tool is useful for exploring the capabilities of the Auth Admin SDK and understanding how to properly format parameters for the call_auth_admin_method tool.

No parameters required.

TDQS

A4.4/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden. It describes what the tool returns ('comprehensive dictionary' with method details) and clarifies it requires no parameters, which is helpful. However, it doesn't mention behavioral aspects like whether this is a read-only operation, if it makes external API calls, potential rate limits, or error conditions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured and front-loaded with the core purpose. Every sentence adds value: the first states what it does, the second details the return content, the third explains usage context, and the fourth clarifies no parameters needed. There is no wasted text.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 0 parameters, no annotations, and no output schema, the description does a good job explaining the purpose, return format, and usage context. However, it could be more complete by specifying the exact structure of the returned dictionary or any prerequisites, though the lack of output schema lowers the bar.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has 0 parameters with 100% schema description coverage, so the baseline is 4. The description explicitly states 'No parameters required,' which reinforces this clearly and adds value by preventing parameter confusion.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the specific action ('Get Python SDK methods specification for Auth Admin') and resource ('Auth Admin methods available in the Supabase Python SDK'). It distinguishes from sibling tools by focusing exclusively on Auth Admin SDK methods, unlike broader tools like get_management_api_spec or get_schemas.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly states when to use this tool ('useful for exploring the capabilities of the Auth Admin SDK and understanding how to properly format parameters for the call_auth_admin_method tool'), providing clear context and naming the specific alternative tool (call_auth_admin_method) it prepares for.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_management_api_specA

Get the complete Supabase Management API specification.

Returns the full OpenAPI specification for the Supabase Management API, including:

  • All available endpoints and operations

  • Required and optional parameters for each operation

  • Request and response schemas

  • Authentication requirements

  • Safety information for each operation

This tool can be used in four different ways:

  1. Without parameters: Returns all domains (default)

  2. With path and method: Returns the full specification for a specific API endpoint

  3. With domain only: Returns all paths and methods within that domain

  4. With all_paths=True: Returns all paths and methods

Parameters:

  • params: Dictionary containing optional parameters:

    • path: Optional API path (e.g., "/v1/projects/{ref}/functions")

    • method: Optional HTTP method (e.g., "GET", "POST")

    • domain: Optional domain/tag name (e.g., "Auth", "Storage")

    • all_paths: Optional boolean, if True returns all paths and methods

Available domains:

  • Analytics: Analytics-related endpoints

  • Auth: Authentication and authorization endpoints

  • Database: Database management endpoints

  • Domains: Custom domain configuration endpoints

  • Environments: Environment configuration endpoints

  • OAuth: OAuth integration endpoints

  • Organizations: Organization management endpoints

  • Projects: Project management endpoints

  • Rest: RESTful API endpoints

  • Secrets: Secret management endpoints

  • Storage: Storage management endpoints

This specification is useful for understanding:

  • What operations are available through the Management API

  • How to properly format requests for each endpoint

  • Which operations require unsafe mode

  • What data structures to expect in responses

SAFETY: This is a low-risk read operation that can be executed in SAFE mode.

A4.7/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden and does an excellent job disclosing behavioral traits. It explicitly states this is a 'low-risk read operation that can be executed in SAFE mode,' describes what information is returned (endpoints, parameters, schemas, auth requirements, safety info), and explains the four different usage patterns. The only minor gap is lack of information about rate limits or pagination, but overall it provides comprehensive behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured and appropriately sized, with clear sections for purpose, usage patterns, parameters, domains, and utility. While comprehensive, every sentence earns its place by adding value. The only minor issue is some redundancy in the safety statement at the end, but overall it's front-loaded with the core purpose and efficiently organized.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity of a tool that returns API specifications with multiple usage patterns, and with no annotations and no output schema, the description provides complete context. It explains what the tool does, how to use it in different scenarios, what parameters mean, what domains are available, what information the specification contains, and safety considerations. This fully compensates for the lack of structured metadata.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage (the schema only shows 'params' as an object with no properties documented), the description fully compensates by providing detailed parameter semantics. It explains all four optional parameters (path, method, domain, all_paths) with examples and clear descriptions of what each does. It also lists available domain values with explanations, effectively documenting what would normally be in the schema's enum or property descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Get the complete Supabase Management API specification' with specific details about what it returns (OpenAPI spec including endpoints, parameters, schemas, auth requirements, safety info). It distinguishes from sibling tools like 'get_auth_admin_methods_spec' by covering the entire Management API rather than just auth methods, and from 'send_management_api_request' by providing documentation rather than executing requests.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit usage guidelines with four distinct scenarios: 1) without parameters returns all domains, 2) with path and method returns specific endpoint spec, 3) with domain only returns all paths/methods in that domain, 4) with all_paths=True returns all paths/methods. It also explains when this tool is useful (understanding available operations, request formatting, unsafe mode requirements, response structures), giving clear context for when to use it versus alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS

B3.2/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It states this is a read operation ('List'), implying it's non-destructive, but doesn't cover other important aspects like authentication requirements, rate limits, error handling, or what the output format looks like. For a tool with zero annotation coverage, this is insufficient.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence that states exactly what the tool does with zero wasted words. It's front-loaded with the core purpose and includes key details (sizes and table counts) without unnecessary elaboration.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (0 parameters, no output schema, no annotations), the description is adequate but has clear gaps. It explains what the tool returns (schemas with sizes and table counts), but without annotations or output schema, it doesn't specify the return format, data types, or any behavioral constraints. This is a minimal viable description.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has 0 parameters, and the schema description coverage is 100% (though empty). The description doesn't need to add parameter semantics, so it meets the baseline of 4 for tools with no parameters. It appropriately doesn't mention any parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose with a specific verb ('List') and resource ('database schemas'), along with what information is included ('sizes and table counts'). It distinguishes from siblings like 'get_tables' and 'get_table_schema' by focusing on schemas rather than tables. However, it doesn't explicitly differentiate from all siblings, so it's not a perfect 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention when to choose this over 'get_tables' or 'get_table_schema', nor does it specify any prerequisites or exclusions. The agent must infer usage from the purpose alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_tablesA

List all tables, foreign tables, and views in a schema with their sizes, row counts, and metadata.

Provides detailed information about all database objects in the specified schema:

  • Table/view names

  • Object types (table, view, foreign table)

  • Row counts

  • Size on disk

  • Column counts

  • Index information

  • Last vacuum/analyze times

Parameters:

  • schema_name: Name of the schema to inspect (e.g., 'public', 'auth', etc.)

A4.2/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden. It discloses that this is a 'low-risk read operation' and can be executed in 'SAFE mode', which clarifies safety and behavioral traits. However, it lacks details on rate limits, permissions needed, or potential performance impacts.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with a clear summary, bulleted details, and a dedicated safety note. It is appropriately sized, but could be slightly more concise by integrating the safety note into the main text.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no annotations and no output schema, the description does a good job explaining the tool's purpose, parameters, and safety. It lists the information returned (e.g., row counts, sizes), but could benefit from clarifying the output format or any limitations.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema description coverage is 0%, so the description must compensate. It explicitly defines the single parameter 'schema_name' with meaning ('Name of the schema to inspect') and examples ('public', 'auth'), adding significant value beyond the bare schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb ('List') and resource ('all tables, foreign tables, and views in a schema') with specific attributes ('sizes, row counts, and metadata'). It distinguishes from siblings like get_schemas (which lists schemas) and get_table_schema (which provides schema details for a single table).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for inspecting database objects in a schema, but does not explicitly state when to use this tool versus alternatives like get_schemas or get_table_schema. No exclusions or prerequisites are mentioned, leaving some ambiguity in context.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_table_schemaA

Get detailed table structure including columns, keys, and relationships.

Returns comprehensive information about a specific table's structure:

  • Column definitions (names, types, constraints)

  • Primary key information

  • Foreign key relationships

  • Indexes

  • Constraints

  • Triggers

Parameters:

  • schema_name: Name of the schema (e.g., 'public', 'auth')

  • table: Name of the table to inspect

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden and does well by explicitly stating 'This is a low-risk read operation that can be executed in SAFE mode.' It discloses safety profile and operational mode, though it could add more about rate limits, permissions needed, or response format.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Perfectly structured with purpose statement, bulleted return details, parameter section, and safety note. Every sentence earns its place, and information is front-loaded with the core purpose first.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read operation with 2 parameters and no output schema, the description provides good coverage of purpose, parameters, and safety. It could benefit from more detail about the return format or example output, but given the context signals, it's mostly complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. It provides clear semantic meaning for both parameters with examples (schema_name: 'public', 'auth') and clarifies that 'table' is the specific table to inspect. This adds significant value beyond the bare schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Get' and resource 'detailed table structure', specifying what information is returned (columns, keys, relationships). It distinguishes from sibling tools like get_schemas and get_tables by focusing on detailed structural metadata rather than lists of objects.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage context through the parameter descriptions and safety note, but doesn't explicitly state when to use this tool versus alternatives like get_tables or execute_postgresql. It provides clear context for inspecting table structure but lacks explicit exclusions or named alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

live_dangerouslyA

Toggle unsafe mode for either Management API or Database operations.

WHAT THIS TOOL DOES: This tool switches between safe (default) and unsafe operation modes for either the Management API or Database operations.

SAFETY MODES EXPLAINED:

  1. Database Safety Modes:

    • SAFE mode (default): Only low-risk operations like SELECT queries are allowed

    • UNSAFE mode: Higher-risk operations including INSERT, UPDATE, DELETE, and schema changes are permitted

  2. API Safety Modes:

    • SAFE mode (default): Only low-risk operations that don't modify state are allowed

    • UNSAFE mode: Higher-risk state-changing operations are permitted (except those explicitly blocked for safety)

OPERATION RISK LEVELS: The system categorizes operations by risk level:

  • LOW: Safe read operations with minimal impact

  • MEDIUM: Write operations that modify data but don't change structure

  • HIGH: Operations that modify database structure or important system settings

  • EXTREME: Destructive operations that could cause data loss or service disruption

WHEN TO USE THIS TOOL:

  • Use this tool BEFORE attempting write operations or schema changes

  • Enable unsafe mode only when you need to perform data modifications

  • Always return to safe mode after completing write operations

USAGE GUIDELINES:

  • Start in safe mode by default for exploration and analysis

  • Switch to unsafe mode only when you need to make changes

  • Be specific about which service you're enabling unsafe mode for

  • Consider the risks before enabling unsafe mode, especially for database operations

  • For database operations requiring schema changes, you'll need to enable unsafe mode first

Parameters:

  • service: Which service to toggle ("api" or "database")

  • enable_unsafe_mode: True to enable unsafe mode, False for safe mode (default: False)

Examples:

  1. Enable database unsafe mode: live_dangerously(service="database", enable_unsafe_mode=True)

  2. Return to safe mode after operations: live_dangerously(service="database", enable_unsafe_mode=False)

  3. Enable API unsafe mode: live_dangerously(service="api", enable_unsafe_mode=True)

Note: This tool affects ALL subsequent operations for the specified service until changed again.

A4.9/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure and does so comprehensively. It explains the safety modes in detail (SAFE vs. UNSAFE for both Database and API), describes risk levels (LOW, MEDIUM, HIGH, EXTREME), and explicitly states that the tool 'affects ALL subsequent operations for the specified service until changed again,' which is crucial behavioral context not evident from the schema alone.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (WHAT THIS TOOL DOES, SAFETY MODES EXPLAINED, etc.) and front-loads the core purpose. While comprehensive, some sections like OPERATION RISK LEVELS could be slightly more concise, but every sentence adds valuable context for a safety-critical tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 2 parameters, 0% schema description coverage, no annotations, and no output schema, the description provides complete context. It explains what the tool does, when to use it, detailed behavioral implications, parameter meanings, examples, and important notes about persistence of the mode change. No additional information is needed for an agent to use this tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description fully compensates by explaining both parameters in detail. It defines 'service' as 'api' or 'database' with clear explanations of what each service controls, and explains 'enable_unsafe_mode' as a boolean with default False, including specific examples of how to use both parameters together in different scenarios.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool 'switches between safe (default) and unsafe operation modes for either the Management API or Database operations,' providing a specific verb ('toggle'/'switch') and resources (API/Database). It distinguishes from siblings by focusing on safety mode configuration rather than direct operations like execute_postgresql or send_management_api_request.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly states when to use this tool ('BEFORE attempting write operations or schema changes'), when not to use it ('Start in safe mode by default for exploration and analysis'), and provides clear alternatives (safe vs. unsafe modes). It also gives specific guidance on risk considerations and returning to safe mode after operations.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

retrieve_logsA

Retrieve logs from your Supabase project's services for debugging and monitoring.

Returns log entries from various Supabase services with timestamps, messages, and metadata. This tool provides access to the same logs available in the Supabase dashboard's Logs & Analytics section.

AVAILABLE LOG COLLECTIONS:

  • postgres: Database server logs including queries, errors, warnings, and system messages

  • api_gateway: API requests, responses, and errors processed by the Kong API gateway

  • auth: Authentication and authorization logs for sign-ups, logins, and token operations

  • postgrest: Logs from the RESTful API service that exposes your PostgreSQL database

  • pooler: Connection pooling logs from pgbouncer and supavisor services

  • storage: Object storage service logs for file uploads, downloads, and permissions

  • realtime: Logs from the real-time subscription service for WebSocket connections

  • edge_functions: Serverless function execution logs including invocations and errors

  • cron: Scheduled job logs (can be queried through postgres logs with specific filters)

  • pgbouncer: Connection pooler logs

PARAMETERS:

  • collection: The log collection to query (required, one of the values listed above)

  • limit: Maximum number of log entries to return (default: 20)

  • hours_ago: Retrieve logs from the last N hours (default: 1)

  • filters: List of filter objects with field, operator, and value (default: []) Format: [{"field": "field_name", "operator": "=", "value": "value"}]

  • search: Text to search for in event messages (default: "")

  • custom_query: Complete custom SQL query to execute instead of the pre-built queries (default: "")

HOW IT WORKS: This tool makes a request to the Supabase Management API endpoint for logs, sending either a pre-built optimized query for the selected collection or your custom query. Each log collection has a specific table structure and metadata format that requires appropriate CROSS JOIN UNNEST operations to access nested fields.

EXAMPLES:

  1. Using pre-built parameters: collection: "postgres" limit: 20 hours_ago: 24 filters: [{"field": "parsed.error_severity", "operator": "=", "value": "ERROR"}] search: "connection"

  2. Using a custom query: collection: "edge_functions" custom_query: "SELECT id, timestamp, event_message, m.function_id, m.execution_time_ms FROM function_edge_logs CROSS JOIN unnest(metadata) AS m WHERE m.execution_time_ms > 1000 ORDER BY timestamp DESC LIMIT 10"

METADATA STRUCTURE: The metadata structure is important because it determines how to access nested fields in filters:

  • postgres_logs: Use "parsed.field_name" for fields like error_severity, query, application_name

  • edge_logs: Use "request.field_name" or "response.field_name" for HTTP details

  • function_edge_logs: Use "function_id", "execution_time_ms" for function metrics

NOTE FOR LLM CLIENTS: When encountering errors with field access, examine the error message to see what fields are actually available in the structure. Start with basic fields before accessing nested metadata.

SAFETY CONSIDERATIONS:

  • This is a low-risk read operation that can be executed in SAFE mode

  • Requires a valid Supabase Personal Access Token to be configured

  • Not available for local Supabase instances (requires cloud deployment)

A4.7/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure and does so comprehensively. It explains the tool's operation ('makes a request to the Supabase Management API endpoint'), includes safety considerations (low-risk read operation, requires Personal Access Token, not available for local instances), and provides metadata structure details crucial for effective use. The 'HOW IT WORKS' and 'SAFETY CONSIDERATIONS' sections add significant value beyond basic functionality.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (PARAMETERS, HOW IT WORKS, EXAMPLES, METADATA STRUCTURE, SAFETY CONSIDERATIONS) that make information easy to find. While comprehensive, some sections like the detailed log collection list (10 items) could be more concise, though each serves a purpose in helping users select the right collection. The front-loaded purpose statement is clear and effective.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with 6 parameters, 0% schema coverage, no annotations, and no output schema, the description provides complete contextual information. It covers purpose, parameters with semantics, usage examples, operational mechanics, metadata structure, safety considerations, and even troubleshooting guidance ('NOTE FOR LLM CLIENTS'). This fully compensates for the lack of structured documentation elsewhere.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Given 0% schema description coverage for 6 parameters, the description compensates exceptionally well. It provides detailed explanations for each parameter including required status, default values, format specifications (especially for the complex 'filters' array), and practical examples showing how to use them. The 'AVAILABLE LOG COLLECTIONS' section effectively documents the valid values for the 'collection' parameter despite no enum in the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose as 'Retrieve logs from your Supabase project's services for debugging and monitoring' with specific verb ('retrieve') and resource ('logs'), and distinguishes it from siblings like 'execute_postgresql' or 'retrieve_migrations' by focusing on log retrieval across multiple services rather than database queries or migration history.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context for when to use this tool (debugging and monitoring Supabase services) and mentions it provides 'access to the same logs available in the Supabase dashboard's Logs & Analytics section,' giving users a familiar reference point. However, it doesn't explicitly state when not to use it or name specific alternatives among the sibling tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

retrieve_migrationsA

Retrieve a list of all migrations a user has from Supabase.

Returns a list of migrations with the following information:

  • Version (timestamp)

  • Name

  • SQL statements (if requested)

  • Statement count

  • Version type (named or numbered)

Parameters:

  • limit: Maximum number of migrations to return (default: 50, max: 100)

  • offset: Number of migrations to skip for pagination (default: 0)

  • name_pattern: Optional pattern to filter migrations by name. Uses SQL ILIKE pattern matching (case-insensitive). The pattern is automatically wrapped with '%' wildcards, so "users" will match "create_users_table", "add_email_to_users", etc. To search for an exact match, use the complete name.

  • include_full_queries: Whether to include the full SQL statements in the result (default: false)

SAFETY: This is a low-risk read operation that can be executed in SAFE mode.

ParametersJSON Schema
NameRequiredDescriptionDefault
include_full_queriesNo
limitNo
name_patternNo

TDQS

A4.3/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden and does well by disclosing the SAFE mode operation, pagination behavior (limit/offset defaults), and pattern matching behavior for name_pattern. It doesn't mention rate limits, authentication needs, or error conditions, but provides solid behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Well-structured with purpose statement, return format details, parameter explanations, and safety note. Every sentence earns its place with no redundancy. The information is front-loaded with the core purpose first.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read operation with no annotations and no output schema, the description provides good completeness: clear purpose, detailed parameter semantics, safety context, and return format details. It could mention authentication requirements or error scenarios, but covers the essential context well.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description fully compensates by explaining all 4 parameters in detail: default values, constraints (max: 100), and behavioral semantics (especially the ILIKE pattern matching with automatic wildcards for name_pattern). This adds significant value beyond the bare schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb ('Retrieve') and resource ('list of all migrations a user has from Supabase'), with specific details about what information is returned. It distinguishes itself from sibling tools like 'retrieve_logs' or 'get_tables' by focusing specifically on migrations.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage through the SAFE mode note and parameter explanations, but doesn't explicitly state when to use this tool versus alternatives like 'retrieve_logs' or 'get_schemas'. No explicit when-not-to-use guidance or named alternatives are provided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

send_management_api_requestA

Execute a Supabase Management API request.

This tool allows you to make direct calls to the Supabase Management API, which provides programmatic access to manage your Supabase project settings, resources, and configurations.

REQUEST FORMATTING:

  • Use paths exactly as defined in the API specification

  • The {ref} parameter will be automatically injected from settings

  • Format request bodies according to the API specification

PARAMETERS:

  • method: HTTP method (GET, POST, PUT, PATCH, DELETE)

  • path: API path (e.g. /v1/projects/{ref}/functions)

  • path_params: Path parameters as dict (e.g. {"function_slug": "my-function"}) - use empty dict {} if not needed

  • request_params: Query parameters as dict (e.g. {"key": "value"}) - use empty dict {} if not needed

  • request_body: Request body as dict (e.g. {"name": "test"}) - use empty dict {} if not needed

PATH PARAMETERS HANDLING:

  • The {ref} placeholder (project reference) is automatically injected - you don't need to provide it

  • All other path placeholders must be provided in the path_params dictionary

  • Common placeholders include:

    • {function_slug}: For Edge Functions operations

    • {id}: For operations on specific resources (API keys, auth providers, etc.)

    • {slug}: For organization operations

    • {branch_id}: For database branch operations

    • {provider_id}: For SSO provider operations

    • {tpa_id}: For third-party auth operations

EXAMPLES:

  1. GET request with path and query parameters: method: "GET" path: "/v1/projects/{ref}/functions/{function_slug}" path_params: {"function_slug": "my-function"} request_params: {"version": "1"} request_body: {}

  2. POST request with body: method: "POST" path: "/v1/projects/{ref}/functions" path_params: {} request_params: {} request_body: {"name": "test-function", "slug": "test-function"}

SAFETY SYSTEM: API operations are categorized by risk level:

  • LOW RISK: Read operations (GET) - allowed in SAFE mode

  • MEDIUM/HIGH RISK: Write operations (POST, PUT, PATCH, DELETE) - require UNSAFE mode

  • EXTREME RISK: Destructive operations - require UNSAFE mode and confirmation

  • BLOCKED: Some operations are completely blocked for safety reasons

SAFETY CONSIDERATIONS:

  • By default, the API client starts in SAFE mode, allowing only read operations

  • To perform write operations, first use live_dangerously(service="api", enable=True)

  • High-risk operations will be rejected with a confirmation ID

  • Use confirm_destructive_operation with the provided ID after reviewing risks

  • Some operations may be completely blocked for safety reasons

For a complete list of available API endpoints and their parameters, use the get_management_api_spec tool. For details on safety rules, use the get_management_api_safety_rules tool.

TDQS

A4.9/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure and does so comprehensively. It details the safety system with risk categories (LOW, MEDIUM/HIGH, EXTREME, BLOCKED), explains the default SAFE mode, specifies that write operations require UNSAFE mode, describes confirmation requirements for destructive operations, and mentions automatic injection of the {ref} parameter.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured with clear sections (REQUEST FORMATTING, PARAMETERS, PATH PARAMETERS HANDLING, EXAMPLES, SAFETY SYSTEM, SAFETY CONSIDERATIONS) but is quite lengthy. While every section adds value, it could be more concise by integrating some safety information more tightly with usage guidance.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity of a 5-parameter API request tool with no annotations and no output schema, the description provides complete context. It covers purpose, usage, parameters, safety considerations, examples, and references to related tools, leaving no significant gaps for an agent to understand and use this tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage for 5 parameters, the description fully compensates by providing detailed parameter explanations. It defines each parameter's purpose, provides examples of valid values, explains how path parameters work with placeholders, and gives concrete usage examples showing all parameters in action.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose as 'Execute a Supabase Management API request' and specifies it provides 'programmatic access to manage your Supabase project settings, resources, and configurations.' This is a specific verb+resource combination that distinguishes it from sibling tools like execute_postgresql or get_management_api_spec.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit guidance on when to use this tool versus alternatives, directing users to 'use the get_management_api_spec tool' for endpoint details and 'use the get_management_api_safety_rules tool' for safety specifics. It also clearly explains when write operations require enabling UNSAFE mode via live_dangerously.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS

A4/5.0
Disambiguation4/5

Most tools have distinct purposes, such as call_auth_admin_method for auth operations, execute_postgresql for SQL queries, and send_management_api_request for API calls. However, get_auth_admin_methods_spec and get_management_api_spec are both specification-fetching tools that could be confused, and confirm_destructive_operation overlaps with safety mechanisms in other tools like execute_postgresql and send_management_api_request, causing minor ambiguity.

Naming Consistency3/5

The naming is mixed with some consistent patterns (e.g., get_* for read operations like get_schemas, get_tables) but deviations like call_auth_admin_method (verb_noun_noun), live_dangerously (phrase), and confirm_destructive_operation (verb_adjective_noun). While readable, the lack of a uniform verb_noun convention across all tools reduces consistency.

Tool Count5/5

With 12 tools, the count is well-scoped for a Supabase server covering database operations, auth management, API requests, logs, migrations, and safety controls. Each tool serves a clear purpose, such as execute_postgresql for SQL and retrieve_logs for monitoring, making the set comprehensive without being overwhelming.

Completeness4/5

The tool set provides broad coverage for Supabase domains, including CRUD for auth (via call_auth_admin_method), database queries, API management, and monitoring. Minor gaps exist, such as no direct tool for managing storage or edge functions beyond API requests, but agents can work around this using send_management_api_request with specifications from get_management_api_spec.
