概要

What is CoinGecko API Server MCP?

CoinGecko API Server MCP is a Node.js Express server that provides a comprehensive interface to the CoinGecko cryptocurrency data API. It supports both the free public API and the Pro API with automatic fallback, and is designed for AI systems like Claude via the MCP (Marketplace Component Program) protocol.

How to use CoinGecko API Server MCP?

Install and run it with npx coingecko-api-server or clone the repository, install dependencies, run npm run setup, then start with npm start. Configure via a .env file (PORT, COINGECKO_API_KEY). In Claude Desktop, provide the server URL (e.g., http://localhost:3000) to access cryptocurrency data through the MCP interface.

Key features of CoinGecko API Server MCP

  • Supports both CoinGecko Free and Pro APIs
  • Automatically falls back to free API if no key provided
  • Provides RESTful endpoints for cryptocurrency data
  • Handles errors with detailed messages and status codes
  • Offers interactive setup via npx
  • Implements JSON-RPC 2.0 endpoint for AI integration

Use cases of CoinGecko API Server MCP

  • Fetch real-time prices and market data for cryptocurrencies
  • Integrate cryptocurrency data into AI assistants like Claude
  • Build applications that need CoinGecko data with simplified setup
  • Use the free API for development and switch to Pro for production

よくある質問

1

What is the difference between the free and Pro API?

The Pro API offers higher rate limits, no throttling, and additional endpoints, but requires an API key. The free API is limited to ~30 calls/minute with potential rate limiting.

2

What are the runtime requirements?

The server runs on Node.js and requires npm to be installed. It can be started via npx without manual cloning.

3

How does the server know which API to use?

If a COINGECKO_API_KEY is provided in the .env file, the server uses the Pro API. Otherwise, it automatically falls back to the free API.

4

Where does the API data come from?

All data is fetched directly from the CoinGecko API via `fetch` calls. No data is stored locally by the server.

5

What transports or authentication does the MCP server use?

The server provides an `/rpc` endpoint using JSON-RPC 2.0 for MCP communication, and an `/mcp/schema` endpoint. No authentication is required for the MCP integration beyond starting the server locally.
