"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.

Safe MCP server and CLI tool for testing, scoring, and inspecting n8n workflows. Features 19 tools for workflow testing, execution traces, tiered scoring, and a built-in node catalog with 800+ node types. Designed with safety-first approach: no credential management, no secrets lifecycle, no auto-fix loops.

A Model Context Protocol (MCP) server for programmatically creating and managing n8n workflows.

Enables users to create, manage, and monitor n8n workflows through natural language using AI interfaces like Claude and Cursor. It supports multi-instance environments and provides tools for workflow lifecycle management, execution monitoring, and tag organization.

A server for programmatically creating and managing n8n workflows with a REST API interface, supporting workflow creation, validation, and export.

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.

MCP server for integrating with n8n, enabling workflow automation and management through natural language.

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

A production-oriented MCP server for PostgreSQL that exposes database operations like query execution, schema introspection, and table metadata to MCP clients such as Claude Desktop and VS Code.

Autonomous AI agent for n8n workflow automation with credential factories, execution helpers, and 4343+ workflow templates. Provides 38 MCP tools for full n8n API coverage.

Enables AI agents to create, retrieve, update, and manage n8n workflows through the n8n API. Supports full workflow lifecycle management including activation, deactivation, and deletion operations.
