Realtime Exchange Rate MCP is a Model Context Protocol server that fetches real-time currency rates, historical data, and multi-currency lookups. It integrates with the AllRatesToday API and works with MCP-compatible clients like Claude Code, Cursor, Claude Desktop, and Windsurf.
Install via npx -y @allratestoday/mcp-server and configure the ALLRATES_API_KEY environment variable with a free key from allratestoday.com/register. Then users add the server to their client's MCP config (for Cursor, Claude Desktop, Windsurf) or use claude mcp add allratestoday (for Claude Code). The server exposes four tools: get_exchange_rate, get_historical_rates, get_rates_authenticated, and list_currencies.
