1. Start the server in HTTP mode:

npx @cryptoapis-io/mcp-aml --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

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

CLI Arguments

HTTP API Key Modes

When using HTTP transport, the server supports two API key modes:

• With --api-key: The key is used for all requests. x-api-key request headers are ignored.
• Without --api-key: Each request must include an x-api-key header with a valid Crypto APIs key. This enables hosting a public server where each user provides their own key.
