Integrates with n8n workflow automation platform to provide conversational access to 525+ nodes including AI-capable nodes and triggers, enabling natural language workflow creation, validation, and management without requiring direct platform knowledge.
  1. Access Your n8n Instance Admin Panel

    • Go to the web address of your n8n instance (e.g., https://your-n8n-instance.com) in your browser.
    • Log in as an admin.
  2. Create an n8n API Key

    • Navigate to Settings > API within the n8n admin interface, or look for a section labeled "Personal API Keys" or "API Credentials".
    • If you're running a self-hosted n8n, you may need to enable API access or generate the API key via your user profile or the API section.
    • Click "Create New API Key" or similar.
    • Copy the generated API key—this will be your N8N_API_KEY.
  3. Find Your n8n API URL

    • The API URL is usually the main URL of your n8n instance, e.g., https://your-n8n-instance.com.
    • If using Docker and connecting locally, you may need to use http://host.docker.internal:5678.
  4. Add ENV Variables in FastMCP Connection Interface

    • In the FastMCP interface, click the "Install Now" button or the section to add ENV variables.
    • Fill in the following:
      • N8N_API_URL: Paste your n8n instance URL (e.g., https://your-n8n-instance.com)
      • N8N_API_KEY: Paste the API key you generated above.
    • Optionally, set:
      • MCP_MODE to stdio
      • LOG_LEVEL to error
      • DISABLE_CONSOLE_OUTPUT to true
  5. Save and Restart

    • Save your changes in the FastMCP connection interface.
    • If you're using Claude Desktop, restart it to apply the new configuration.

Note: If you only want documentation and validation tools (not workflow management), you can skip the API URL and key—just leave those ENV values empty. For workflow creation/management features, both N8N_API_URL and N8N_API_KEY are required.
