MCP Inspector

n8n

1. Start the server in HTTP mode:

npx @cryptoapis-io/mcp-market-data --transport http --port 3000 --api-key YOUR_API_KEY

1. In your n8n workflow, add an AI Agent node
2. Under Tools, add an MCP Client Tool and set the URL to http://localhost:3000/mcp

n8n in Docker: localhost inside the container is not your machine. Start the server with --host 0.0.0.0 and MCPAUTHTOKEN set (see Exposing the server beyond localhost), use http://host.docker.internal:3000/mcp as the URL, and add an Authorization: Bearer header to the MCP Client Tool credential.

All servers default to port 3000. Use --port to assign different ports when running multiple servers.
