Yes. n8n instance-level MCP passed every step of our test in Cursor on Oct 16, 2026: it installed, connected, its tools were visible, and an agent used it to finish a real task.

Steps

  1. install OK
  2. connect OK
  3. tools visible OK
  4. agent task: node lookup OKread-only node catalog search (n8n node library), no account or workflow run
  5. agent task: run fixture OKdiscover + run an automation on a local, self-hosted instance: the fixture echoes its input, so the fresh {TOKEN} can only come back if the server actually ran it
