What is the Coin Api MCP MCP server?

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 tools it exposes

The server publishes 3 tools. What each one is for:

  • listing-coins — Fetches a paginated list of all active cryptocurrencies with the latest market data
  • get-coin-info — Retrieves detailed information about a specific cryptocurrency
  • get-coin-quotes — Fetches the latest market quotes for one or more cryptocurrencies

Getting it running

Installation 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.

What it needs from you

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.

How it compares

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.

Things to watch

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Coin Api MCP to MCP-compatible AI assistants such as Claude and Cursor, exposing 3 tools (listing-coins, get-coin-info, get-coin-quotes) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Coin Api MCP directly.
