Overview

What is UniRate MCP?

UniRate MCP is a Model Context Protocol server that connects the UniRate API to any MCP-compatible AI assistant (Claude, Cursor, Continue, etc.). It gives assistants first-class access to real-time currency conversion and exchange rates for over 170 fiat and major crypto currencies, plus historical rates back to 1999 (Pro plan). A free tier is available without a credit card.

How to use UniRate MCP?

Install globally with npm install -g @unirate/mcp or run on demand with npx @unirate/mcp. Get a free API key at unirateapi.com. Configure the server in your MCP client’s JSON config (e.g., Claude Desktop or Cursor) by setting the UNIRATE_API_KEY environment variable. To run as a remote endpoint, use the --http flag (e.g., unirate-mcp --http 3001). The package also exports buildServer(client) for programmatic use in edge runtimes.
