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.
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.
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.
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.
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 stdioLOG_LEVEL to errorDISABLE_CONSOLE_OUTPUT to true
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.
