N8n MCP

An MCP server for n8n that gives Claude, Cursor, and other AI agents tools for generating workflows, linting, diagnosing failed executions, and driving live n8n instances. Its 12 documented tools cover workflow, execution. It runs locally over stdio via the published package.

People connecting automation tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install N8n MCP

before you install - you'll need

Set N8N_API_URL, N8N_API_KEY before connecting.

Claude Code

claude mcp add ratamaha-git-n8n-mcp -- npx -y @automatelab/n8n-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "ratamaha-git-n8n-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@automatelab/n8n-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package @automatelab/n8n-mcp - the @automatelab scope differs from the repo owner (ratamaha-git); confirm it's the project's official package

registry namespace io.github.ratamaha-git is GitHub-verified and matches the repo owner
