Overview

This MCP server bridges the gap between AI assistants and the n8n automation platform. It grants models structured access to over 2,100 core and community nodes, alongside detailed schema data for node properties and operations. By utilizing this server, AI models can interpret n8n node capabilities and configuration options more effectively within their reasoning context. The tool surfaces critical development data, including AI-capable tool variants and ranked workflow configurations extracted from templates. It supports deep integration with n8n documentation and community-verified nodes, making it a resource for developers looking to incorporate n8n's extensive ecosystem into AI-assisted workflow design.

Our verdict

With a security score of 50/100, this project is classified as high-risk. The score is impacted significantly by the fact that the server is community-maintained rather than official, and both OAuth support and authentication methods have not yet undergone independent review. Potential users should treat this as an experimental integration and strictly follow the developer's warning to avoid direct AI edits to production workflows, opting instead for tested development environments.

Provides access to 2,175 individual n8n automation nodes
Contains 87% coverage of official n8n documentation
Maintained by 30 contributors, reducing bus-factor risk
Lightweight build with only 17 direct dependencies

Security architecture is unverified for authentication and OAuth
Read-only capabilities remain currently unreviewed
Not developed or managed by the official n8n vendor

Setup

Claude Desktop

{
  "mcpServers": {
    "n8n-mcp": {
      "args": [
        "-y",
        "n8n-mcp"
      ],
      "command": "npx"
    }
  }
}

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows), then restart Claude Desktop. Some servers require API keys or tokens as environment variables — check the project's README and add an "env" object if needed.

No read-only mode — running this grants full read/write access.
No built-in authentication — anyone with access to this config can invoke every tool it exposes.
