CoinGecko Server is a Model Context Protocol (MCP) server. It provides an interface to the CoinGecko Pro API for accessing cryptocurrency market data.
To use it, install the package via npm. You must set up your environment with a required CoinGecko API key. The server can then be configured for use with Claude Desktop or OpenAI function calling.
Key features include a paginated list of supported cryptocurrencies and coin ID lookup by name or symbol. It also provides historical price, market cap, and volume data, as well as OHLC (Open, High, Low, Close) candlestick charts. A local coin cache with refresh capability is included for performance.
Use cases range from retrieving real-time cryptocurrency prices to analyzing historical price trends. It is also designed for integrating live crypto data into applications using OpenAI's ecosystem.
A CoinGecko Pro API key is required to run the server. It is fully compatible with OpenAI function calling. For API rate limits and usage guidelines, please refer to the official CoinGecko Pro API documentation.
