Installation

Direct invocation

You can run the MCP Server directly via npx:

export COINGECKO_PRO_API_KEY="My Pro API Key"
export COINGECKO_DEMO_API_KEY="My Demo API Key"
export COINGECKO_ENVIRONMENT="pro"
npx -y @coingecko/coingecko-mcp@latest

Via MCP Client

There is a partial list of existing clients at modelcontextprotocol.io. If you already
have a client, consult their documentation to install the MCP server.

For clients with a configuration JSON, it might look something like this:

{
  "mcpServers": {
    "coingecko_api": {
      "command": "npx",
      "args": ["-y", "@coingecko/coingecko-mcp"],
      "env": {
        "COINGECKO_PRO_API_KEY": "My Pro API Key",
        "COINGECKO_DEMO_API_KEY": "My Demo API Key",
        "COINGECKO_ENVIRONMENT": "pro"
      }
    }
  }
}

Claude Code

If you use Claude Code, you can install the MCP server by running the command below in your terminal. You will need to set your
environment variables in Claude Code's .claude.json, which can be found in your home directory.

claude mcp add coingecko_coingecko_mcp_api --env COINGECKO_PRO_API_KEY="My Pro API Key" COINGECKO_DEMO_API_KEY="My Demo API Key" -- npx -y @coingecko/coingecko-mcp

Code Mode

This MCP server is built on the "Code Mode" tool scheme. In this MCP Server,
your agent will write code against the TypeScript SDK, which will then be executed in an
isolated sandbox. To accomplish this, the server will expose two tools to your agent:

• The first tool is a docs search tool, which can be used to generically query for
  documentation about your API/SDK.

• The second tool is a code tool, where the agent can write code against the TypeScript SDK.
  The code will be executed in a sandbox environment without web or filesystem access. Then,
  anything the code returns or prints will be returned to the agent as the result of the
  tool call.

Using this scheme, agents are capable of performing very complex tasks deterministically
and repeatably.

Running remotely

Launching the client with --transport=http launches the server as a remote server using Streamable HTTP transport. The --port setting can choose the port it will run on, and the --socket setting allows it to run on a Unix socket.

Authorization can be provided via the following headers:

A configuration JSON for this server might look like this, assuming the server is hosted at http://localhost:3000:

{
  "mcpServers": {
    "coingecko_coingecko_typescript_api": {
      "url": "http://localhost:3000",
      "headers": {
        "x-cg-pro-api-key": "My Pro API Key"
      }
    }
  }
}
