Description
If you use n8n to automate tasks and also use an AI assistant like Claude to help you build things, you've probably run into the gap between them: your AI assistant doesn't actually know what n8n can do node by node. n8n-MCP closes that gap — it teaches AI assistants the full catalog of n8n's automation building blocks, so they can help you build a working workflow instead of guessing.
n8n-MCP is a Model Context Protocol (MCP) server that exposes n8n's full node catalog — over 2,500 nodes, with 99% documentation coverage — to AI assistants like Claude, Cursor, and Windsurf. Rather than an AI assistant hallucinating node names or configuration options, n8n-MCP gives it grounded, accurate knowledge of what's actually available in n8n, plus access to thousands of workflow templates. It's usable via a hosted dashboard (100 free tool calls/day) or self-hosted against your own n8n instance. With 22.8k GitHub stars and enterprise adoption, it's become close to a standard bridge between AI coding assistants and n8n's automation ecosystem.
💬 Our review
The short version: n8n-MCP is the missing manual that lets AI assistants like Claude actually understand n8n's 2,500+ automation nodes instead of guessing at workflow configuration — a genuinely useful fix for a specific, common frustration.
Its real strength is documentation coverage: 99% of n8n's nodes are documented for the AI to reference, which is what actually determines whether an AI-built workflow works on the first try or needs five rounds of debugging. The free tier (100 calls/day) is enough to evaluate it before committing to self-hosting.
The catch is that it's infrastructure for an existing n8n setup — it doesn't replace n8n or give you automation on its own, and you'll want your own n8n instance for any real production use. If you're already building n8n workflows with an AI assistant's help, this is close to essential. If you don't use n8n, it's not relevant to you.
