n8n Community Nodes MCP Server

n8n Community Nodes MCP Server

A focused MCP server for:

• Community n8n packages from npm
• Official n8n docs and built-in nodes from n8n-io/n8n-docs

Why use this

• Discover and search community n8n nodes directly from your AI assistant
• Access official n8n documentation without leaving your editor
• Context-optimized responses using TOON format to save tokens

Smart search

Searches run in parallel across multiple npm tags, results are deduplicated and ranked:

Filler phrases are stripped from queries — "how to send slack messages" and "slack messages" return the same results.

Token-efficient responses (TOON)

All responses are encoded in TOON (Token-Oriented Object Notation) — a compact format designed for LLMs. Instead of repeating JSON keys in every object, TOON declares them once and streams rows:

[10]{package,name,description,version,downloadsLastWeek}:
 n8n-nodes-slack-bolt,Slack Bolt,Advanced Slack integration,1.2.0,340
 n8n-nodes-discord,Discord,Discord bot nodes for n8n,0.9.1,210
 ...

30–60% fewer tokens per response — more room in context, lower cost per call.
