Doppler MCP Server

A Model Context Protocol (MCP) server that wraps the Doppler CLI for seamless secrets management integration with Claude and other MCP clients.

Overview

This MCP server provides a bridge between MCP-compatible applications (like Claude Desktop) and the Doppler CLI, allowing you to manage secrets, projects, configs, and environments through natural language interactions.

Related MCP server: Doppler MCP Server

Prerequisites

  • Node.js 18 or higher

  • Doppler CLI installed and authenticated

  • An active Doppler account with appropriate permissions

Installation

From Source

# Clone or navigate to the repository
cd doppler-mcp-server

# Install dependencies
npm install

# Build the project
npm run build

Configuration

Claude Desktop

Add this server to your Claude Desktop configuration file:

MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Windows: %APPDATA%\Claude\claude_desktop_config.json

      "command": "node",
      "args": ["/absolute/path/to/doppler-mcp-server/build/index.js"]
    }
  }
}

Other MCP Clients

For other MCP clients, configure them to run:

node /path/to/doppler-mcp-server/build/index.js

Available Tools

The server exposes the following Doppler CLI operations as MCP tools:

Usage Examples

Once configured, you can interact with Doppler through your MCP client:

"List all my Doppler projects"
"Get the API_KEY secret from my production config"
"Set DATABASE_URL to postgres://... in the dev config"
"Create a new project called my-app"
"Show me all secrets in the staging config"

Authentication

This server uses the Doppler CLI's authentication. Make sure you've authenticated the Doppler CLI before using this server:

doppler login

You can verify your authentication status:

doppler me

Development

Build

npm run build

Watch Mode

npm run watch

How It Works

This server:

  1. Listens for MCP tool requests via stdio

  2. Translates tool calls into Doppler CLI commands

  3. Executes the commands using your local Doppler CLI installation

  4. Returns the results in JSON format back to the MCP client

Troubleshooting

"Command not found: doppler"

Make sure the Doppler CLI is installed and available in your PATH:

which doppler
doppler --version

"Authentication required"

Authenticate with Doppler:

doppler login

Server not appearing in Claude Desktop

  1. Check that the path in claude_desktop_config.json is correct and absolute

  2. Restart Claude Desktop completely

  3. Check the Claude Desktop logs for errors

Security Considerations

  • This server executes Doppler CLI commands with the permissions of the authenticated user

  • Secrets are transmitted through the MCP protocol - ensure your MCP client is trusted

  • The server does not store any secrets, it only proxies requests to the Doppler CLI

C2.9/5.0
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 creation operation but doesn't mention any behavioral traits such as permissions required, whether it's idempotent, error conditions (e.g., duplicate names), or what happens upon success (e.g., returns a config object). This leaves significant gaps for a mutation tool.

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 directly states the tool's purpose without any fluff or redundant information. It's appropriately sized and front-loaded, making it easy to parse quickly.

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

Completeness2/5

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

Given this is a mutation tool (create operation) with no annotations and no output schema, the description is incomplete. It doesn't cover behavioral aspects like authentication needs, error handling, or return values, which are critical for an AI agent to use it correctly. The high schema coverage helps with parameters, but overall context is lacking.

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

Parameters3/5

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

Schema description coverage is 100%, so the schema already documents all three parameters (name, project, environment) with clear descriptions. The description adds no additional parameter semantics beyond implying the tool creates a config, which aligns with the schema but doesn't provide extra context like format examples or constraints.

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 action ('Create') and resource ('new config in a Doppler project'), making the purpose immediately understandable. It distinguishes from siblings like 'doppler_configs_list' (list vs create) but doesn't explicitly differentiate from 'doppler_projects_create' (creates projects vs configs) or 'doppler_secrets_set' (sets secrets vs creates configs).

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 prerequisites (e.g., needing an existing project), exclusions, or comparisons to sibling tools like 'doppler_secrets_set' for adding secrets to a config or 'doppler_configs_list' for viewing existing configs.

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

doppler_configs_listB

List all configs in a Doppler project

ParametersJSON Schema
NameRequiredDescriptionDefault
projectNoThe Doppler project name (optional if set via doppler setup)

TDQS

B3.1/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states this is a list operation, implying it's read-only and non-destructive, but doesn't explicitly confirm safety, describe pagination, rate limits, authentication needs, or return format. For a tool with zero annotation coverage, this leaves significant gaps in behavioral understanding.

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 with zero wasted words. It's appropriately sized for a simple list tool and front-loads the core purpose immediately.

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 low complexity (single optional parameter, list operation) and high schema coverage, the description is minimally adequate. However, with no annotations and no output schema, it should ideally provide more context about what 'configs' are and the return format to be fully complete for agent use.

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

Parameters3/5

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

Schema description coverage is 100%, so the input schema already fully documents the single parameter. The description adds no additional meaning beyond what the schema provides (e.g., it doesn't explain what 'configs' are or provide context on the project parameter). Baseline 3 is appropriate when the schema does all the work.

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 action ('List all configs') and resource ('in a Doppler project'), providing a specific verb+resource combination. However, it doesn't distinguish this tool from its sibling 'doppler_configs_create', which would be needed for a perfect score.

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 like 'doppler_configs_create' or 'doppler_secrets_list'. It mentions the project parameter is optional if set via doppler setup, but this is already covered in the input schema description, so it doesn't add usage guidance beyond what's structured.

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

doppler_environments_listC

List all environments in a Doppler project

ParametersJSON Schema
NameRequiredDescriptionDefault
projectNoThe Doppler project name (optional if set via doppler setup)

TDQS

C2.9/5.0
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 mentions listing environments but fails to describe key traits such as pagination, rate limits, authentication requirements, or the format of returned data. This leaves significant gaps for an agent to understand how the tool behaves beyond its basic function.

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 directly states the tool's purpose without unnecessary words. It is front-loaded and appropriately sized, making it easy to parse quickly.

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

Completeness2/5

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

Given the lack of annotations and output schema, the description is incomplete for a tool that likely returns a list of environments. It does not cover behavioral aspects like response format, error handling, or usage constraints, which are essential for an agent to invoke it correctly in context.

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

Parameters3/5

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

The input schema has 100% description coverage, with the 'project' parameter documented as optional if set via Doppler setup. The description does not add any additional meaning beyond what the schema provides, such as examples or constraints, so it meets the baseline of 3 for high schema coverage without extra value.

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 verb ('List') and resource ('all environments in a Doppler project'), making the purpose immediately understandable. It doesn't explicitly differentiate from sibling tools like 'doppler_configs_list' or 'doppler_projects_list', which would require a 5, but the specificity of 'environments' provides adequate clarity.

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 like 'doppler_configs_list' or 'doppler_projects_list', nor does it mention prerequisites or exclusions. It simply states what the tool does without context for selection among siblings.

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

ParametersJSON Schema
NameRequiredDescriptionDefault

No parameters

TDQS

B3.4/5.0
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 mentions authentication ('authenticated Doppler user'), which hints at security context, but fails to describe key traits like whether this is a read-only operation, potential rate limits, error conditions, or the format of returned information. This leaves significant gaps for an agent to understand how to handle the tool effectively.

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, clear sentence that directly states the tool's purpose without any fluff or redundancy. It is front-loaded with the essential information, making it highly efficient and easy to parse for an AI agent.

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 minimally adequate. It covers the basic purpose but lacks details on behavioral aspects like response format, error handling, or authentication requirements. For a tool that likely returns user data, more context on what information is provided would enhance completeness, though the absence of an output schema partially excuses this gap.

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%, so there are no parameters to document. The description appropriately doesn't add unnecessary param details, earning a high baseline score. However, it doesn't explicitly state the lack of parameters, which could slightly improve clarity, preventing a perfect 5.

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 ('Get') and resource ('information about the current authenticated Doppler user'), making it easy to understand what it does. However, it doesn't explicitly differentiate itself from potential sibling tools like 'doppler_projects_list' or 'doppler_secrets_list' that might also return user-related information, preventing a perfect score.

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 by specifying 'current authenticated Doppler user,' suggesting it should be used when user identity or details are needed. However, it provides no explicit guidance on when to use this tool versus alternatives (e.g., for authentication checks vs. other user-related operations) or any prerequisites, leaving some ambiguity.

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

doppler_projects_createC

Create a new Doppler project

ParametersJSON Schema
NameRequiredDescriptionDefault
nameYesThe name of the project to create
descriptionNoOptional description for the project

TDQS

C2.9/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. While 'Create' implies a mutation operation, the description doesn't specify permissions required, whether the operation is idempotent, rate limits, or what happens on failure (e.g., duplicate project names). For a creation tool with zero annotation coverage, this leaves significant gaps in understanding its behavior.

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 directly states the tool's purpose without unnecessary words. It is front-loaded and wastes no space, making it easy for an agent to parse quickly. Every word earns its place by conveying essential information.

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

Completeness2/5

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

Given the complexity of a creation tool with no annotations and no output schema, the description is insufficiently complete. It doesn't address behavioral aspects like error handling, authentication requirements, or return values. While the schema covers parameters well, the overall context for safe and effective use is lacking, especially for a mutation operation.

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

Parameters3/5

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

The description adds no parameter semantics beyond what the input schema provides. With 100% schema description coverage, the schema already documents both parameters ('name' and 'description') clearly. The baseline score of 3 reflects adequate coverage by the schema, but the description doesn't enhance understanding with examples, constraints, or contextual usage.

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 verb ('Create') and resource ('new Doppler project'), making the purpose immediately understandable. It distinguishes from sibling tools like 'doppler_projects_list' by specifying creation rather than listing. However, it doesn't explicitly differentiate from other creation tools like 'doppler_configs_create', which would require mentioning project-specific context.

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 prerequisites (e.g., authentication needs), when not to use it, or how it relates to sibling tools like 'doppler_projects_list' for checking existing projects before creation. The agent must infer usage from the tool name alone.

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 the action ('List') but doesn't describe how the listing works (e.g., pagination, ordering, rate limits, or authentication needs). For a list operation with zero annotation coverage, this is a significant gap in transparency.

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 directly states the tool's purpose without any wasted words. It's appropriately sized and front-loaded, making it easy for an agent to parse quickly.

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), the description is adequate as a basic list operation. However, with no annotations and no output schema, it lacks details on behavioral aspects like response format or limitations, which could be helpful for an agent. It meets minimum viability but has clear gaps.

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 input schema has 0 parameters with 100% coverage, so the schema fully documents the absence of parameters. The description doesn't need to add parameter information, and it correctly implies no inputs are required for listing all projects. A baseline of 4 is appropriate for zero-parameter tools.

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 verb ('List') and resource ('all Doppler projects'), making the purpose immediately understandable. However, it doesn't differentiate from sibling tools like 'doppler_configs_list' or 'doppler_environments_list' beyond specifying the resource type, which prevents a perfect score.

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 like 'doppler_configs_list' or 'doppler_environments_list'. It doesn't mention prerequisites, context, or exclusions, leaving the agent to infer usage based on the resource name alone.

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

doppler_runB

Run a command with Doppler secrets injected as environment variables

ParametersJSON Schema
NameRequiredDescriptionDefault
commandYesThe command to run with Doppler secrets
projectNoThe Doppler project name (optional if set via doppler setup)
configNoThe Doppler config name (optional if set via doppler setup)

TDQS

B3.2/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden. It states the tool runs a command with secret injection but lacks details on permissions, security implications, error handling, or output behavior. For a tool that executes commands with sensitive data, this is a significant gap in behavioral disclosure.

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 front-loads the core functionality without unnecessary words. Every part of the sentence directly contributes to understanding the tool's purpose.

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

Completeness2/5

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

Given the complexity of running commands with secret injection, no annotations, and no output schema, the description is incomplete. It fails to address critical aspects like security risks, execution environment, or what happens after the command runs, leaving significant gaps for an AI agent.

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

Parameters3/5

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

Schema description coverage is 100%, so the schema already documents all three parameters. The description adds no additional meaning beyond implying secret injection occurs, which is covered by the tool's purpose. Baseline 3 is appropriate as the schema does the heavy lifting.

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 ('Run a command') and resource ('with Doppler secrets injected as environment variables'), distinguishing it from sibling tools that manage configs, projects, or secrets rather than executing commands with secret injection.

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?

No guidance is provided on when to use this tool versus alternatives like direct command execution or other Doppler tools. The description mentions optional parameters if set via 'doppler setup', but this is a technical note rather than usage context or exclusions.

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

doppler_secrets_deleteC

Delete a secret from Doppler

ParametersJSON Schema
NameRequiredDescriptionDefault
nameYesThe name of the secret to delete
projectNoThe Doppler project name (optional if set via doppler setup)
configNoThe Doppler config name (optional if set via doppler setup)

TDQS

C2.9/5.0
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 the destructive action ('Delete') but doesn't cover critical aspects like whether deletion is permanent, requires specific permissions, has rate limits, or what happens on success/failure. For a mutation tool with zero annotation coverage, this leaves significant gaps in understanding its behavior.

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 with zero waste. It's front-loaded with the core action and resource, making it easy to parse quickly. Every word earns its place without redundancy or unnecessary elaboration.

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

Completeness2/5

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

Given this is a destructive mutation tool with no annotations and no output schema, the description is incomplete. It doesn't address the tool's impact, error handling, or return values, leaving the agent with insufficient context for safe and effective use. More detail is needed for such a high-stakes operation.

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

Parameters3/5

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

Schema description coverage is 100%, with all parameters documented in the schema. The description doesn't add any meaning beyond what the schema provides—it doesn't explain parameter interactions, default behaviors, or provide examples. Baseline 3 is appropriate since the schema does the heavy lifting, but no extra value is added.

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 action ('Delete') and resource ('a secret from Doppler'), providing a specific verb+resource combination. However, it doesn't differentiate from sibling tools like 'doppler_secrets_set' or 'doppler_secrets_get' beyond the obvious action difference, missing explicit scope or capability distinctions.

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?

No guidance is provided on when to use this tool versus alternatives. It doesn't mention prerequisites, when-not-to-use scenarios, or compare with siblings like 'doppler_secrets_set' for updates or 'doppler_secrets_list' for checking before deletion. The description lacks any contextual usage instructions.

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

doppler_secrets_getC

Get a secret value from Doppler

ParametersJSON Schema
NameRequiredDescriptionDefault
nameYesThe name of the secret to retrieve
projectNoThe Doppler project name (optional if set via doppler setup)
configNoThe Doppler config name (optional if set via doppler setup)

TDQS

C2.9/5.0
Behavior2/5

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

With no annotations provided, the description carries full burden for behavioral disclosure but offers minimal information. It states the tool retrieves a secret value but doesn't cover critical aspects like authentication requirements, rate limits, error handling, or what happens if the secret doesn't exist. For a secrets management tool with zero annotation coverage, this leaves significant gaps in understanding its behavior.

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 extremely concise at just 6 words, front-loading the core purpose without any wasted language. Every word earns its place by directly communicating the tool's function, making it easy to parse quickly.

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

Completeness2/5

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

Given the complexity of secrets management (sensitive operations) and the absence of both annotations and an output schema, the description is insufficiently complete. It doesn't address security implications, return format, error conditions, or how it differs from sibling tools. For a tool with 3 parameters and no structured behavioral hints, more context is needed.

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

Parameters3/5

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

The schema description coverage is 100%, with all parameters clearly documented in the schema itself. The description adds no additional parameter semantics beyond what's already in the schema (e.g., it doesn't explain format requirements for 'name' or clarify the relationship between 'project' and 'config'). This meets the baseline for high schema coverage but doesn't provide extra value.

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 action ('Get') and resource ('a secret value from Doppler'), making the purpose immediately understandable. However, it doesn't differentiate from sibling tools like doppler_secrets_list (which lists secrets) or doppler_secrets_set (which sets secrets), missing the opportunity to clarify this is specifically for retrieving a single secret's value.

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 doppler_secrets_list for browsing secrets or doppler_secrets_set for modifying them, nor does it explain prerequisites like authentication or setup requirements beyond what's implied in the schema.

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the action but doesn't cover critical aspects like whether this is a read-only operation, if it requires authentication, what the output format looks like (e.g., list of secrets with metadata), or any rate limits. This leaves significant gaps for an agent to understand the tool's behavior.

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 directly states the tool's purpose without any wasted words. It's front-loaded and appropriately sized for a simple list operation, making it easy to parse quickly.

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

Completeness2/5

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

Given the lack of annotations and output schema, the description is incomplete for a tool that lists secrets. It doesn't explain what the output contains (e.g., secret names, values, metadata), how results are structured, or any behavioral constraints. For a tool with no structured support, this leaves too much unspecified for reliable agent use.

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

Parameters3/5

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

The input schema has 100% description coverage, clearly documenting both optional parameters ('project' and 'config') as optional if set via 'doppler setup'. The description doesn't add any additional meaning beyond what the schema provides, such as explaining default behaviors or dependencies, so it meets the baseline for high schema coverage.

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 verb ('List') and resource ('all secrets in a Doppler config'), making the purpose immediately understandable. However, it doesn't explicitly differentiate from sibling tools like 'doppler_secrets_get' (which presumably retrieves a single secret) or 'doppler_configs_list' (which lists configs rather than secrets).

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?

No guidance is provided on when to use this tool versus alternatives. The description doesn't mention sibling tools like 'doppler_secrets_get' for retrieving individual secrets or 'doppler_configs_list' for listing configs, nor does it specify prerequisites or context for usage beyond the basic action.

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

C2.9/5.0
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 but offers minimal information. It states the tool sets a secret value, implying a write/mutation operation, but doesn't cover critical aspects like authentication requirements, rate limits, idempotency (e.g., whether it creates or updates), error handling, or side effects. This leaves significant gaps for a tool that modifies data.

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 extremely concise—a single sentence that directly states the tool's purpose without any fluff. It's front-loaded and wastes no words, making it easy for an agent to parse quickly. Every part of the sentence earns its place by conveying the core functionality.

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

Completeness2/5

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

Given the complexity of a write operation (setting secrets) with no annotations and no output schema, the description is incomplete. It lacks details on behavioral traits (e.g., permissions, idempotency), output format, error cases, and usage context. While the schema covers parameters well, the overall context for safe and effective tool invocation is insufficient.

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

Parameters3/5

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

The input schema has 100% description coverage, so the schema already documents all parameters (name, value, project, config) thoroughly. The description adds no additional parameter semantics beyond what's in the schema, such as format examples or constraints. With high schema coverage, a baseline score of 3 is appropriate, as the description doesn't compensate but also doesn't need to given the schema's completeness.

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 action ('Set') and resource ('a secret value in Doppler'), making the purpose immediately understandable. It distinguishes from siblings like doppler_secrets_get (retrieve) and doppler_secrets_delete (remove), though it doesn't explicitly name these alternatives. The description is specific but could be slightly more precise about what 'set' entails (e.g., create or update).

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 doppler_secrets_get for retrieval, doppler_secrets_delete for removal, or other secret management tools. There's no context about prerequisites, error conditions, or typical use cases, leaving the agent with minimal usage direction.

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

A3.5/5.0
Disambiguation5/5

Each tool has a clearly distinct purpose targeting specific resources and actions, with no ambiguity between them. For example, doppler_secrets_get retrieves a single secret value, while doppler_secrets_list enumerates all secrets, and doppler_run is uniquely for executing commands with injected secrets.

Naming Consistency5/5

All tools follow a consistent doppler_<resource>_<action> naming pattern using snake_case throughout. This predictable structure makes it easy to understand each tool's function at a glance, such as doppler_configs_create and doppler_secrets_delete.

Tool Count5/5

With 11 tools, the server is well-scoped for managing Doppler projects, configs, environments, and secrets. Each tool earns its place by covering essential CRUD operations and specific workflows like doppler_run, avoiding both bloat and gaps.

Completeness4/5

The toolset provides strong coverage for core Doppler operations, including project, config, environment, and secret management with create/list/get/set/delete actions. A minor gap exists in missing update operations for configs or projects, but agents can work around this by recreating resources as needed.
