You run a real-time cryptocurrency data MCP server that integrates with the CoinCap API to provide exchange details and current rates. You can deploy it alongside your MCP client to fetch up-to-date crypto information in a structured, typed way, with built-in retry and rate-limiting to keep requests reliable.

How to use

You connect to this MCP server from your MCP client to retrieve two core capabilities: detailed cryptocurrency exchange information and current USD rates for cryptocurrencies. Use the server to fetch data like exchange volumes, rankings, trading pairs, and live price data. The server is designed to work with the MCP server SDK and handles API call reliability, so your client can rely on consistent responses.

How to install

Prerequisites are Node.js 18+ and npx. Follow these steps to set up the MCP server locally and run it with your MCP client.

# 1) Install dependencies for the project
npm install

# 2) Build the server
npm run build

# 3) Start the server via MCP entry point (local stdio configuration)
npx realtime-crypto-mcp-server

Configuration and usage details

The MCP server is configured as a local (stdio) server that you run with npx. The configuration is provided to your MCP client to start the server on demand. The following example shows how to register the server in your MCP client configuration.

{
  "mcpServers": {
    "realtime-crypto": {
      "command": "npx",
      "args": ["realtime-crypto-mcp-server"]
    }
  }
}

Notes on usage and capabilities

This server provides two tools through its MCP interface: one for exchange details and one for current cryptocurrency rates. It includes built-in rate limiting and retry logic to gracefully handle CoinCap API limits. Use these tools to keep your application synchronized with the latest market data.
