Coin MCP Server

The Coin MCP Server bridges AI assistants with real‑time cryptocurrency data from CoinMarketCap. By exposing a set of declarative tools, it allows developers to query market listings, obtain detailed coin profiles, and retrieve up‑to‑date quotes without handling API keys or request plumbing themselves. This abstraction is especially valuable for conversational agents that need to answer questions about coin prices, market caps, or historical performance on the fly.

At its core, the server offers three intuitive tools. returns a paginated catalogue of active cryptocurrencies, supporting rich filtering (price ranges, market‑cap thresholds) and multi‑currency conversions. fetches static metadata—such as description, website, and developer information—for one or more coins identified by ID, slug, or symbol. delivers the latest market quotes, again keyed by ID, slug or symbol. Each tool is designed to be lightweight and stateless, making it easy for AI assistants to chain calls or embed results directly into responses.

Real‑world use cases include financial advisory bots that can provide instant price checks, portfolio trackers that update holdings in real time, and educational assistants that explain market dynamics with up‑to‑date figures. Because the server handles authentication internally, developers can focus on natural language understanding and dialogue flow rather than API management. The MCP’s prompt‑based invocation model also means that a single user query can trigger multiple tool calls, enabling complex workflows such as “compare the top 5 coins by market cap in USD and EUR” with minimal code.

Integration into AI workflows is seamless: a Claude or other MCP‑compatible assistant simply declares the desired tool and passes parameters; the server responds with structured JSON, which the assistant can embed or format as needed. The ability to specify sorting directions and conversion currencies adds flexibility, allowing agents to tailor outputs for different audiences or regulatory contexts. Overall, the Coin MCP Server provides a robust, low‑maintenance gateway to cryptocurrency data, empowering developers to build richer, more interactive AI experiences without deep domain expertise.
