n8n MCP Server

n8n MCP Server is an MCP server that connects AI assistants to an n8n automation instance using natural language. It is designed for developers, DevOps engineers, and workflow automation teams who want to orchestrate tasks without leaving their AI chat interface. By communicating with the n8n REST API and webhook endpoints, the server enables language models to inspect existing workflows, retrieve execution logs, create or edit automated sequences, and activate or deactivate triggers on demand. Users can trigger executions programmatically through standard API calls or basic-auth webhooks and pass structured payload data directly into automated steps. In addition to active tooling, the server exposes read-only resource endpoints for listing workflows and monitoring execution states. This setup allows AI agents running in MCP-compatible clients to diagnose pipeline failures, inspect run histories, stop ongoing workflow executions, and manage entire integration graphs remotely without manual dashboard navigation.

Generate an API key in your n8n web interface under Settings > API > API Keys. 4. Add the server configuration to your Claude Desktop configuration file (claude_desktop_config.json) or VS Code settings.json: json { "mcpServers": { "n8n-local": { "command": "n8n-mcp-server", "env": { "N8N_API_URL": "http://localhost:5678/api/v1", "N8N_API_KEY": "your_n8n_api_key", "N8N_WEBHOOK_USERNAME": "username", "N8N_WEBHOOK_PASSWORD": "password" } } } } 5. Restart your MCP client to initialize the server tools.

What you can do with n8n MCP Server

• Triggering n8n webhooks with dynamic JSON payloads directly from conversational prompts in Claude Desktop or Cursor. * Inspecting past execution failures and error logs to debug broken automated business processes in real time. * Activating or deactivating existing n8n workflows based on automated deployment checks or team schedules. * Creating and updating n8n workflow nodes and parameters through natural language instructions without visiting the browser interface. * Stopping stuck or long-running workflow executions remotely using execution management tools during operational incidents.
