  1. Hosted: sign up at dashboard.n8n-mcp.com for an API key (free tier 100 calls/day)
  2. Or self-host via npx, Docker, Railway or local per docs/SELF_HOSTING.md

Permissions and security

What it can access

  • With API key, can create, update and run workflows on your n8n instance

Security notes from the maintainers

  • README: never edit production workflows directly with AI; back up first
  • N8N_MCP_ACCESS_TOKEN is a separate secret from N8N_API_KEY

Review the source before granting an agent access to credentials or production systems. We document what the maintainers state; we do not audit code.

Limitations

  • Management tools require n8n API configuration
  • Hosted free tier limited to 100 tool calls/day
