Coinmarketcap is a Model Context Protocol (MCP) server that wraps the CoinMarketCap API. It provides a standardized interface for accessing cryptocurrency market data, exchange information, and other blockchain-related metrics. This tool is designed for developers and analysts who want to integrate live crypto data into AI assistants or automated workflows using the MCP protocol.
Install by running npx @shinzolabs/coinmarketcap-mcp (recommended), cloning the repository manually, or using Smithery. Configure the server in your claude_desktop_config.json with a CoinMarketCap API key and a subscription level (COINMARKETCAP_API_KEY and SUBSCRIPTION_LEVEL). The subscription level you choose determines which endpoints are available.

The README lists available endpoints grouped by subscription level: Basic, Hobbyist, Startup, Standard, and Enterprise. For example, `cryptoOhlcvLatest` requires Startup or above, while `blockchainStatisticsLatest` requires Enterprise. Set the `SUBSCRIPTION_LEVEL` environment variable to match your plan.
Node.js and a package manager (npm or pnpm) are needed. The server is distributed as an npm package and relies on Zod for validation. No additional database or external service is required beyond the CoinMarketCap API.
The README does not mention streaming; all endpoints are request‑response. Data freshness depends on the CoinMarketCap API’s update cycle.
Set two environment variables in your MCP client configuration: `COINMARKETCAP_API_KEY` (your API key) and `SUBSCRIPTION_LEVEL` (e.g., "Basic"). The server uses these to authenticate and to determine which endpoints to expose.
