n8n-MCP

n8n-MCP is an MCP server that connects AI tools to n8n to build, validate, test, and deploy automation workflows.

n8n-MCP connects AI tools like Claude, ChatGPT, and Cursor to n8n via the Model Context Protocol. It allows users to build, validate, test, debug, and deploy workflows directly within their n8n instance using natural language. The platform offers two ways to run: a zero-setup hosted service with one-click OAuth or an open-source MIT-licensed server running locally via Node.js or Docker. It includes live workflow access, real schema resolution, and validation tools to catch errors. The service is designed for users who want to automate workflow creation and maintenance using their preferred AI assistants without manual copy-pasting.
