What is the Coinmarketcap MCP MCP server?

Coinmarketcap MCP MCP server exists for a simple reason — assistants are far more useful when they can act on Coinmarketcap MCP directly instead of describing what you should do. A complete MCP for the CoinMarketCap API.

What you get

If you don't have an API key, first sign up to receive a free Basic key here.

  • Complete coverage of the CoinMarketCap API
  • Fetch data on the latest crypto trends, market movements, and global market metrics
  • Access to detailed OHLCV data with Standard subscription or higher
  • Type-safe parameter validation with Zod

What the assistant can call

Once Coinmarketcap MCP is connected, these are the calls the assistant has available:

  • priceConversion — Convert an amount of one cryptocurrency or fiat currency into another
  • getPostmanCollection — Get Postman collection for the API
  • Cryptocurrency — The Cryptocurrency tool exposed by this server
  • Exchange — The Exchange tool exposed by this server
  • Index — The Index tool exposed by this server
  • Tools — The Tools tool exposed by this server
  • Other — The Other tool exposed by this server
  • Content — The Content tool exposed by this server
  • Community — The Community tool exposed by this server
  • Blockchain — The Blockchain tool exposed by this server

Configuration and credentials

You will need 2 environment variables: COINMARKETCAP_API_KEY, SUBSCRIPTION_LEVEL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Setting it up

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

Choosing this one

Plenty of payments and commerce 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. Coinmarketcap MCP's toolset — priceConversion, getPostmanCollection, Cryptocurrency and 7 more — is a fair guide to whether it matches your workflow. It is maintained by shinzo-labs; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Before you rely on it

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • With 10 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Coinmarketcap MCP.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the coinmarketcap mcp mcp server does with a few real requests.
