n8n-MCP: an MCP server giving Claude and Cursor knowledge of 3135 n8n nodes

n8n-MCP plugs into Claude Desktop, Claude Code, Windsurf, Cursor, VS Code and other clients as an MCP server. It catalogs 3135 n8n nodes (840 core + 2295 community, 1878 of them verified), with 99% node property coverage, 66.5% operation coverage, 86% official docs coverage, plus 2352 workflow templates with AI metadata and 156 real configuration examples pulled from popular templates. It also identifies 267 AI-capable tool variants. For developers building n8n workflows in Cursor or Claude Code, this means querying any node's property schema, operation types and ready-made templates inside the editor, with no browser tab-switching to the official docs. The project offers a hosted cloud version (free tier of 100 tool calls per day) and self-hosting options (npx, Docker, Railway); self-hosting supports connecting to an n8n instance's API and instance-level MCP endpoint via N8N_API_KEY and N8N_MCP_ACCESS_TOKEN. Teams using n8n for production automation should heed the author's explicit warning: don't let AI edit production workflows directly. Validate on copies and in dev environments first, since AI-generated parameter configs can be unpredictable. The server also supports Cloudflare Access service-token auth, but tokens are only sent to the N8N_API_URL origin to avoid leaking into webhook calls to other hosts.
