Watch out for

• It has the same power as your n8n API key

  It can create, change, delete and run workflows, including Code nodes, and manage credentials. Use a key with the least access you need, or none for docs-only mode. github.com

• Telemetry is on by default

  It sends tool usage, sanitized workflow structures and your edit intent text to the maintainer's EU-hosted service. Set N8N_MCP_TELEMETRY_DISABLED=true to turn it off. github.com

• Update often and keep HTTP mode private

  Most published advisories hit shared HTTP deployments. Update to the latest version, and do not expose HTTP mode to a shared network. github.com

• Workflow text reaches your assistant

  Workflow names, descriptions and run results go to the model. On a shared n8n, someone who can edit workflows could plant instructions, so review changes before you approve them. github.com

• It keeps local workflow backups

  Full workflow JSON, including node settings, is saved before each update and kept 30 days by default. github.com
