Rate-API MCP Server

The official Model Context Protocol server for Rate-API.com. It gives Claude and other MCP clients exchange rates for 160+ currencies (updated hourly), currency conversion, historical rates, daily time series and fluctuation, crypto, precious-metal and end-of-day stock prices, usage and quota checks, and rate alerts.

Once connected, you can just ask: "What's 250 EUR in Japanese yen?" or "How has USD/TRY moved over the last 30 days?" and the assistant calls the API for you.
