Install N8n in Claude Code, Cursor or VS Code

Runs npx -y mcp-n8n on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the N8n repository's README, as published. We do not edit it. Read it on GitHub

MCP n8n Server

Operate and build n8n from Cursor or Claude — administration of your instance (users, projects, executions, audit) and a full builder loop: a catalog of 560 nodes with real parameter schemas extracted from the official n8n packages, validation before saving, automatic repair, snapshots with rollback and diff, per-node execution debugging, health reports, and full-instance backup.

Two env vars. Runs on your machine (stdio) or as a remote HTTP server. No hosted account.

🎯 Token Optimization

This server is optimized to minimize token consumption, addressing one of the biggest issues with MCP servers - excessive API token usage.

What We've Optimized:

  • 90% reduction in tokens for workflow listing with new n8nlistworkflows_summary endpoint
  • Field filtering - request only the data you need
  • Smart defaults - reduced from 100 to 10-20 results per query
  • Intelligent warnings - alerts when operations will consume significant tokens

See TOKENOPTIMIZATION.md for detailed usage guide.**
