What it does

An MCP server that connects Claude Desktop, ChatGPT and others to an n8n instance, so "build me a workflow that does X" turns into an actual workflow you can inspect, run and manage. That also means an assistant with the ability to execute production automations — ones that send mail and write to other systems — so point it at a test instance first and hand it a scoped credential rather than a full-access one. Quiet since March 2026. MIT.

Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.
