n8n
- Start the server in HTTP mode:
npx @cryptoapis-io/mcp-aml --transport http --port 3000 --api-key YOUR_API_KEY
- In your n8n workflow, add an AI Agent node
- 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.

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.
npx @cryptoapis-io/mcp-aml --transport http --port 3000
Stdio transport always requires an API key at startup.
Important: API Key Required
Warning: Making requests without a valid API key — or with an incorrect one — may result in your IP being banned from the Crypto APIs ecosystem. Always ensure a valid API key is configured before starting any server.
Remote MCP Server
Crypto APIs provides an official remote MCP server with all tools available via HTTP Streamable transport at https://ai.cryptoapis.io/mcp. Pass your API key via the x-api-key header — no installation required.
