"Using PostgreSQL with n8n Workflow Automation" matching MCP servers:

Enables AI-powered building, optimization, debugging, and management of n8n workflows directly from Claude. Features workflow analysis, execution monitoring, security audits, drift detection, and intelligent error debugging with best practices guidance.

A Model Context Protocol (MCP) server that generates production-ready n8n workflows from natural language prompts. Transform simple descriptions into fully validated, deployable automation workflows using AI-powered code generation.

Statically analyzes exported n8n automation workflows for security issues and returns structured findings.

Enables AI assistants to review workflow status in n8n instances, including active/inactive counts and workflows with recent errors.

Used to create an assistant integrated with n8n that can search n8n documentation, example workflows, and community forums.

A comprehensive MCP server that provides full control over n8n automation workflows through natural language. It offers 43 tools for managing workflows, executions, credentials, and data tables, with safety features like write-mode protection and double-validated workflow creation.

Wraps n8n with an MCP server and vector storage to enable semantic search, management, and execution of automated workflows. It integrates with other tools to make workflows searchable and orchestratable within a larger automation ecosystem.

A Model Context Protocol server that exposes AI workflow templates as callable tools, enabling MCP clients to list templates, inspect their input/output schemas, and execute them synchronously or asynchronously to get structured results.

MCP server for n8n workflow automation, enabling management of workflows, executions, credentials, tags, users, and webhooks via an MCP-compatible client.

Enables AI harnesses to maintain a persistent memory layer backed by a local SQLite file, providing MCP tools to add, search, deprecate, and synchronize facts without deleting history.

A secure MCP server that lets AI assistants directly interact with PostgreSQL databases via tools like create_table, list_tables, and execute_sql, plus a web configurator for managing connections.

Enables multi-agent code review and iterative improvement loop using different LLM backends, with deterministic scoring and audit trail.

Enables fetching weather forecasts for the USA via NWS API and for Israel via browser automation using Playwright.

A lightweight, powerful, and flexible workflow engine that executes tasks defined in YAML configuration files.

MCP server providing access to n8n documentation and workflow templates, enabling LLM agents to search, read, and retrieve workflow examples for automated workflow creation.

Manages workflows, executions, and folders on a self-hosted n8n instance through its public REST API, enabling MCP clients to create, update, activate, list, and trigger workflows via natural language.

Enables management of n8n workflows, executions, credentials, tags, and variables via MCP tools. Supports stdio, Claude Code, and Claude Web with optional Authentik OAuth.

Architecture diagram with concurrency capacity and bottleneck estimates from any codebase.

An MCP server for auditing automation health, finding failures, stale logs, and non-functional endpoints that report success while quietly failing.

Enables comprehensive PostgreSQL database monitoring, analysis, and management through natural language queries. Provides performance insights, bloat analysis, vacuum monitoring, and intelligent maintenance recommendations across PostgreSQL versions 12-17.
