Cursor n8n MCP Server

Cursor n8n Workflow Builder MCP

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "alicankiraz1-cursor-n8n-builder": {
      "command": "node",
      "args": [
        "/path/to/cursor-n8n-mcp/dist/index.js"
      ],
      "env": {
        "MCP_MODE": "stdio",
        "LOG_LEVEL": "error",
        "N8N_API_KEY": "your-api-key",
        "N8N_API_URL": "https://your-n8n-instance.com"
      }
    }
  }
}

This MCP server lets you control Cursor’s AI-powered assistant capabilities to manage n8n workflows through the n8n REST API. It provides workflow lifecycle operations, activation controls, execution history access, webhook triggering, and built‑in help so your assistant can work with n8n smoothly and reliably.

How to use

You interact with the MCP server through an MCP client to manage n8n workflows via the n8n REST API. Use it to list, create, update, delete, and activate or deactivate workflows. Retrieve execution histories and details to understand workflow behavior. Trigger workflows on demand through webhook URLs and consult built‑in documentation and node information to compose valid workflows.

When your AI assistant requests actions, convert those intents into MCP commands that call the n8n API. The server handles errors gracefully by retrying failed requests with exponential backoff and surfaces helpful error messages to guide resolution. Ensure your n8n instance URL and an API key are correctly configured, and set an appropriate log level to help with debugging.

How to install

Prerequisites you need on your machine: Node.js and npm (Node 12+ is typical for modern MCP servers). You also need access to your n8n instance with a valid API key.

# Install locally from source
git clone https://github.com/alicankiraz1/cursor-n8n-mcp.git
cd cursor-n8n-mcp

npm install
npm run build

node dist/index.js setup

Optionally, you can use the provided install script to set up the MCP server quickly.

./install.sh

Configuration and startup

Create or edit a global MCP configuration file at ~/.cursor/mcp.json to register the MCP server with your client. Provide the command to run the server, the arguments, and environment variables required for n8n access.

{
  "mcpServers": {
    "cursor-n8n-mcp": {
      "command": "node",
      "args": ["/path/to/cursor-n8n-mcp/dist/index.js"],
      "env": {
        "MCP_MODE": "stdio",
        "LOG_LEVEL": "error",
        "N8N_API_URL": "https://your-n8n-instance.com",
        "N8N_API_KEY": "your-api-key"
      }
    }
  }
}

Security and reliability notes

The MCP server uses a 30‑second timeout for API requests and automatic retries with exponential backoff to improve reliability when the n8n API temporarily fails or is slow to respond. Keep API keys and endpoint URLs secure, and prefer a least-privilege API key for production environments.
