CoinGecko's official MCP server provides cryptocurrency prices, market charts, exchange data and token metadata. A free keyless remote server is available with shared rate limits, and a separate Pro endpoint uses your CoinGecko API key for higher limits and the full toolset. It can also run locally via npx with a Demo or Pro key.
