A Model Context Protocol server that provides access to CoinMarketCap's cryptocurrency data. This server enables AI-powered applications to retrieve cryptocurrency listings, quotes, and detailed information about various coins. That is what the coin api mcp mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
The server publishes 3 tools. What each one is for:
listing-coins — Fetches a paginated list of all active cryptocurrencies with the latest market dataget-coin-info — Retrieves detailed information about a specific cryptocurrencyget-coin-quotes — Fetches the latest market quotes for one or more cryptocurrenciesInstallation goes through your MCP client rather than a global install: point it at @smithery/cli on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Configuration is passed through the environment: COINMARKETCAP_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.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Coin Api MCP's toolset — listing-coins, get-coin-info, get-coin-quotes — is a fair guide to whether it matches your workflow. It is maintained by longmans; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
