A Model Context Protocol (MCP) server and OpenAI function calling service for interacting with the CoinGecko Pro API
A Model Context Protocol (MCP) server and OpenAI function calling service for interacting with the CoinGecko Pro API. That is what the mcp coingecko server mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
Update: CoinGecko now has an official MCP server: https://docs.coingecko.com/reference/mcp-server
The server publishes 8 tools. What each one is for:
get-coins — Get a paginated list of supported coinsfind-coin-ids — Look up CoinGecko IDs for coin names/symbolsget-historical-data — Get historical price, market cap, and volume dataget-ohlc-data — Get OHLC candlestick datarefresh-cache — Refresh the local coin list cacheOHLCData — The OHLCData tool exposed by this serverHistoricalData — The HistoricalData tool exposed by this serverCoinInfo — The CoinInfo tool exposed by this serverThe server ships on npm as coingecko-server, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Configuration is passed through the environment: COINGECKO_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Among the AI and media services options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. MCP Coingecko Server's toolset — get-coins, find-coin-ids, get-historical-data and 5 more — is a fair guide to whether it matches your workflow. It is maintained by crazyrabbitLTC; worth a glance at recent repository activity before you build anything load-bearing on it.
