n8n

A Model Context Protocol (MCP) server that allows AI assistants to interact with n8n workflows through natural language. This project provides a Model Context Protocol (MCP) server that empowers AI assistants to seamlessly interact with n8n, a popular workflow automation tool. It acts as a bridge, enabling AI assistants to programmatically manage and control n8n workflows and executions using natural language commands. - Node.js 20 or later - n8n instance with API access enabled ``` `npm install -g @leonardsellem/n8n-mcp-server` ``` ``` `# Clone the repository git clone https://github.com/leonardsellem/n8n-mcp-server.git cd n8n-mcp-server # Install dependencies npm install # Build the project npm run build # Optional: Install globally npm install -g .` ``` You can also run the server using Docker: ``` `# Pull the image docker pull leonardsellem/n8n-mcp-server # Run the container with your n8n API configuration docker run -e N8N_API_URL=http://your-n8n:5678/api/v1 \ -e N8N_API_KEY=your_n8n_api_key \ -e N8N_WEBHOOK_USERNAME=username \ -e N8N_WEBHOOK_PASSWORD=password \ leonardsellem/n8n-mcp-server` ``` How you update the server depends on how you initially installed it. If you installed the server using`npm install -g @leonardsellem/n8n-mcp-server`: - Open your terminal or command prompt. - Run the following command to get the latest version: ``` `npm install -g @leonardsellem/n8n-mcp-server@latest` ``` If you cloned the repository and installed from source: - Open your terminal or command prompt. - Navigate to the directory where you cloned the project: ``` `cd path/to/n8n-mcp-server` ``` - If you run the server directly using a command like`node build/index.js`in your AI assistant's MCP configuration, ensure the path is still correct. Using`npm install -g .`and then`n8n-mcp-server`as the command should keep this consistent. If you are running the server using Docker: - Pull the latest image from Docker Hub: ``` `docker pull leonardsellem/n8n-mcp-server:latest` ``` ``` `docker stop <your_container_name_or_id> docker rm <your_container_name_or_id>` ``` ``` `docker run -e N8N_API_URL=http://your-n8n:5678/api/v1 \ -e N8N_API_KEY=your_n8n_api_key \ -e N8N_WEBHOOK_USERNAME=username \ -e N8N_WEBHOOK_PASSWORD=password \ leonardsellem/n8n-mcp-server:latest` ``` Create a`.env`file in the directory where you'll run the server, using`.env.example`as a template: Configure the following environment variables: - Open your n8n instance in a browser - Go to Settings > API > API Keys - Create a new API key with appropriate permissions - Copy the key to your`.env`file After building the server (`npm run build`), you need to configure your AI assistant (like VS Code with the Claude extension or the Claude Desktop app) to run it. This typically involves editing a JSON configuration file. **Example Configuration (e.g., in VS Code`settings.json`or Claude Desktop`claude_desktop_config.json`):** ``` `{ "mcpServers": { // Give your server a unique name "n8n-local": { // Use 'node' to execute the built JavaScript file "command": "node", // Provide the *absolute path* to the built index.js file "args": [ "/path/to/your/cloned/n8n-mcp-server/build/index.js" // On Windows, use double backslashes: // "C:\\path\\to\\your\\cloned\\n8n-mcp-server\\build\\index.js" ], // Environment variables needed by the server "env": { "N8N_API_URL": "http://your-n8n-instance:5678/api/v1", // Replace with your n8n URL "N8N_API_KEY": "YOUR_N8N_API_KEY", // Replace with your key // Add webhook credentials only if you plan to use webhook tools // "N8N_WEBHOOK_USERNAME": "your_webhook_user", // "N8N_WEBHOOK_PASSWORD": "your_webhook_password" }, // Ensure the server is enabled "disabled": false, // Default autoApprove settings "autoApprove": [] } // ... other servers might be configured here } }` ``` - Replace`/path/to/your/cloned/n8n-mcp-server/`with the actual absolute path where you cloned and built the repository. - Use the correct path separator for your operating system (forward slashes`/`for macOS/Linux, double backslashes`\\`for Windows). - Ensure you provide the correct`N8N_API_URL`(including`/api/v1`) and`N8N_API_KEY`. - The server needs to be built (`npm run build`) before the assistant can run the`build/index.js`file. The server provides the following tools: This MCP server supports executing workflows through n8n webhooks. To use this functionality: - Create a webhook-triggered workflow in n8n. - Set up Basic Authentication on your webhook node. - Use the`run_webhook`tool to trigger the workflow, passing just the workflow name. ``` `const result = await useRunWebhook({ workflowName: "hello-world", // Will call <n8n-url>/webhook/hello-world data: { prompt: "Hello from AI assistant!" } });` ``` The webhook authentication is handled automatically using the`N8N_WEBHOOK_USERNAME`and`N8N_WEBHOOK_PASSWORD`environment variables. - `workflow_list`: List all workflows - `workflow_get`: Get details of a specific workflow - `workflow_create`: Create a new workflow - `workflow_update`: Update an existing workflow - `workflow_delete`: Delete a workflow - `workflow_activate`: Activate a workflow - `workflow_deactivate`: Deactivate a workflow - `execution_run`: Execute a workflow via the API - `run_webhook`: Execute a workflow via a webhook - `execution_get`: Get details of a specific execution - `execution_list`: List executions for a workflow - `execution_stop`: Stop a running execution The server provides the following resources: - `n8n://workflows/list`: List of all workflows - `n8n://workflow/{id}`: Details of a specific workflow - `n8n://executions/{workflowId}`: List of executions for a workflow - `n8n://execution/{id}`: Details of a specific execution The n8n MCP Server is a community-driven project, and its future direction will be shaped by your feedback and contributions!
