CoinMarketCap MCP Server

The CoinMarketCap MCP Server is a ready‑to‑use bridge that exposes the full breadth of the CoinMarketCap API to AI assistants following the Model Context Protocol. It solves a common pain point for developers: integrating live cryptocurrency market data into conversational agents without wrestling with authentication, rate limits, or schema inconsistencies. By presenting a single, type‑safe interface, the server lets agents query market caps, price charts, exchange listings, and on‑chain metrics with confidence that the responses will match the API’s expectations.

At its core, the server translates MCP calls into authenticated CoinMarketCap requests. It supports every endpoint available in the public API, from simple ticker lookups to detailed OHLCV (Open‑High‑Low-Close‑Volume) series that require a Standard subscription or higher. The implementation uses Zod for parameter validation, ensuring that every request the assistant sends is syntactically correct before it reaches CoinMarketCap. This reduces runtime errors and speeds up development cycles, as developers can rely on compile‑time guarantees rather than guessing about payload shapes.

Key capabilities include:

• Real‑time market data – Fetch the latest price, volume, and market‑cap statistics for any cryptocurrency.
• Historical trends – Retrieve OHLCV data over arbitrary time ranges, useful for charting or back‑testing strategies.
• Exchange and liquidity insights – List exchanges, trading pairs, and liquidity metrics to inform arbitrage or portfolio decisions.
• Global market metrics – Access aggregate indices, circulating supply figures, and other macro‑level indicators that help contextualize individual assets.

These features make the server ideal for a range of real‑world scenarios. A financial chatbot can answer “What’s the current price of Bitcoin?” or “Show me the 30‑day trend for Ethereum.” A portfolio manager’s assistant can pull exchange rankings to suggest diversification strategies. Even a data‑driven news bot can embed live market stats into headlines, ensuring readers see the most up‑to‑date figures.

Integration with AI workflows is straightforward. Once added to an MCP client, the server becomes a first‑class tool in the agent’s repertoire. Agents can invoke methods such as or , receive structured JSON responses, and feed those directly into downstream prompts or visualizations. Because the server handles authentication via environment variables, developers can keep API keys out of source code and rely on secure deployment practices.

What sets this MCP server apart is its complete coverage of the CoinMarketCap API combined with a developer‑friendly, type‑safe interface. It eliminates boilerplate, reduces the risk of malformed requests, and provides a single point of truth for all market data needs. For any team building AI applications that depend on accurate, real‑time cryptocurrency information, the CoinMarketCap MCP Server delivers a robust, plug‑and‑play solution that scales from small prototypes to production deployments.
