Give your AI assistant a live window into the foreign-exchange market. A Model Context Protocol server that lets Claude Code, Cursor, Claude Desktop, Windsurf, and any MCP-compatible client fetch real-time currency rates, historical series, and multi-currency lookups from the AllRatesToday API.
After installation, your assistant can answer questions like:
- "What's the current USD to EUR rate?"
- "Show me how GBP/JPY moved over the last 30 days."
- "Convert 250 USD into CAD at a real rate."
- "Compare USD against EUR, GBP, and JPY simultaneously."
🚀 Why this server?
- 📡 Live mid-market rates — 160+ ISO 4217 currencies, refreshed every ~60 seconds
- 📈 Historical series built in —
1d/7d/30d/1ywindows with sensible granularity per period - 🧰 Eight focused tools —
get_exchange_rate,get_historical_rates,get_rates_authenticated,list_currencies,list_central_banks,get_official_rates,get_reference_rate,request_trial_key; small surface, easy for the model to use correctly - 🔌 Works everywhere MCP does — stdio transport, MCP 1.x; Claude Code, Cursor, Claude Desktop, Windsurf, or any generic host
- 🔓 Works with no API key — installs and answers out of the box from open official central-bank tables (ECB first, else the bank that issues one of the two currencies); a free key unlocks real-time rates for 160+ currencies
- 🛡️ Honest about what it returned — every keyless answer says which rate it is and when it was published; API errors map to clear, actionable messages
- 🔒 Nothing leaks — only the request parameters and your API key ever reach allratestoday.com; never conversation context
