FAQ from CoinGecko API Server MCP

What is the difference between the free and Pro API?

The Pro API offers higher rate limits, no throttling, and additional endpoints, but requires an API key. The free API is limited to ~30 calls/minute with potential rate limiting.

What are the runtime requirements?

The server runs on Node.js and requires npm to be installed. It can be started via npx without manual cloning.

How does the server know which API to use?

If a COINGECKO_API_KEY is provided in the .env file, the server uses the Pro API. Otherwise, it automatically falls back to the free API.

Where does the API data come from?

All data is fetched directly from the CoinGecko API via fetch calls. No data is stored locally by the server.

What transports or authentication does the MCP server use?

The server provides an /rpc endpoint using JSON-RPC 2.0 for MCP communication, and an /mcp/schema endpoint. No authentication is required for the MCP integration beyond starting the server locally.
