From the repository

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.

Claude Desktop / Cursor

Paste into your MCP client config file to install this server.
