Coinmarket MCP Server

The Coinmarket MCP Server bridges the gap between AI assistants and real‑time cryptocurrency market data by exposing a lightweight, protocol‑compliant interface to the CoinMarketCap API. For developers building AI‑powered financial tools, this server eliminates the need to manage authentication, rate limits, and data parsing themselves. Instead, a Claude (or any MCP‑compatible) assistant can invoke simple tools or query resources to retrieve up‑to‑date currency listings and token quotes with a single, well‑structured request.

At its core, the server implements two primary tool endpoints. returns the latest snapshot of all supported cryptocurrencies, including market cap, volume, and circulating supply. fetches real‑time price data for a specific token, identified by either its slug (e.g., bitcoin) or symbol (e.g., BTC). These tools are designed to be stateless and idempotent, making them ideal for repeated use in conversational AI workflows where a user might ask for the price of Bitcoin multiple times or compare several assets side by side.

The server also exposes a resource layer using a custom URI scheme. Each resource represents an individual market note or data point, identified by a unique name and accompanied by a plain‑text description. This resource model aligns with the MCP specification, allowing assistants to reference market data in a semantically meaningful way—much like linking to a Wikipedia article or a local file. Developers can therefore embed direct references to specific tokens within dialogue, enabling richer context and more precise queries.

Integration with AI workflows is straightforward: a developer configures the server in their Claude desktop configuration file, providing only an API key. Once registered, the assistant automatically lists available tools and resources when queried about market data. In practice, this means a user can ask, “Show me the latest list of top 10 cryptocurrencies,” and the assistant will invoke , parse the response, and present a concise table. Similarly, “What’s the current price of Ethereum?” triggers , returning a single value that can be incorporated into financial analysis or portfolio tracking.

Unique advantages of this MCP server include its adherence to the CoinMarketCap API’s latest version, ensuring compatibility with new endpoints as they are released. The custom URI scheme provides a clean abstraction over raw JSON, allowing developers to treat market data as first‑class resources that can be cached, logged, or indexed. Because the server is self‑contained and requires only a single environment variable for configuration, it scales effortlessly from local prototypes to production deployments without code changes.

In summary, the Coinmarket MCP Server equips AI assistants with instant access to reliable cryptocurrency market data. By abstracting API complexity into intuitive tools and resources, it empowers developers to build conversational finance applications—portfolio trackers, trading assistants, or market research bots—with minimal overhead and maximum reliability.
