MCP Radar

n8n MCP Server

The n8n MCP Server exposes n8n's 500+ nodes and workflow API to your AI. You can say "build a workflow that summarises yesterday's new Stripe orders into Slack every morning" and the AI looks up the node parameters, assembles the JSON, and creates the workflow.

What it really saves is documentation time — every n8n node has a different parameter shape, so building anything complex by hand means constant doc lookups. This server ships the node definitions, so the AI gets an accurate parameter schema instead of guessing.

Why use it

Good for: people already running n8n who find canvas-dragging slow, and for having the AI debug workflows that failed.

Before connecting: it can create and modify workflows, which means giving the AI write access to your automation. Point it at a test instance first rather than production.

Frequently Asked Questions

Does it need n8n Cloud, or does self-hosted work?

Either. It talks to n8n's API, so both cloud and self-hosted instances work — you supply the instance URL and an API key.

Can the AI actually run workflows?

Yes, it can trigger executions and read execution history to diagnose failures. That's exactly why permissions should stay conservative.
