N8N MCP Server

MCP server implementation for n8n workflow automation

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "illuminaresolutions-n8n-mcp-server": {
      "command": "n8n-mcp-server",
      "args": [],
      "env": {
        "N8N_HOST": "https://your-n8n-instance.com",
        "N8N_API_KEY": "your-api-key-here"
      }
    }
  }
}

This MCP server provides secure, standardized access to your n8n workflows, executions, credentials, and related data so you can control and automate n8n from language models and other MCP clients.

How to use

To use the n8n MCP server, connect your MCP client to the local server and perform actions such as listing workflows, retrieving details, executing workflows, and managing credentials. Start by configuring the server in your MCP client so it runs as a local or remote endpoint, then issue high-level actions like listing workflows, running a workflow, or inspecting credentials. Ensure your n8n instance is reachable and that your API key has the required permissions.

How to install

Prerequisites: You need Node.js and npm installed on your system.

Option 1: Install from npm (recommended)

npm install -g @illuminaresolutions/n8n-mcp-server

Option 2: Install from source

Clone the repository, install dependencies, build, and start the server in the background.

git clone https://github.com/illuminaresolutions/n8n-mcp-server.git
cd n8n-mcp-server
npm install
npm run build
nohup npm start > n8n-mcp.log 2>&1 &
```

To stop the server, run:
```
pkill -f "node build/index.js"
