# n8n Community Nodes MCP Server

[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](./LICENSE)

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:

| Signal      | Weight |
|-------------|--------|
| Name match  | 40%    |
| Tag match   | 30%    |
| Description | 20%    |
| Popularity  | 10%    |

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)](https://github.com/toon-format/toon) — 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.

## Recommended (Hosted MCP)

Use the hosted endpoint by default:

- `https://n8n-community-mcp.masmoudi.dev/mcp`
