  • get_exchange_rate

    Use this when the user asks 'what is X in Y?', 'convert X to Y', 'current rate of EUR/USD', or any single fiat-to-fiat live exchange rate question. Returns the latest mid-market rate as a JSON object like { rate: 0.9234, source } meaning 1 source = 0.9234 target. Does NOT support cryptocurrencies, commodities, or arithmetic on amounts. For multiple targets in one call use get_rates_authenticated;

  • get_historical_rates

    Use this for fixed-window time-series questions like 'how has EUR/USD moved this week', 'show me the last month of GBP/JPY', or 'chart 1-year history of AUD/USD'. Returns { source, target, period, data: [{ date, rate, timestamp }, ...] } — sampling is fixed per period (1d=hourly, 7d/30d=daily, 1y=weekly) and the window always ends NOW. For a specific past datetime use get_rates_authenticated with

  • get_rates_authenticated

    Use this for (a) one source against multiple targets in a single call ('USD vs EUR, GBP, JPY'), or (b) the rate at a specific past datetime ('EUR/USD at 2025-03-14T12:00Z'), optionally bucketed by hour/day/week/month. Returns { rates: [{ rate, source, target, time }, ...] } — one row per target × time bucket. For a single live pair use get_exchange_rate. For fixed lookback windows (1d/7d/30d/1y en

  • list_currencies

    Call this BEFORE other tools when you are unsure whether a currency code is supported, or when the user asks 'what currencies do you support?', 'is X a valid currency?', or 'what is the symbol for X?'. Returns { currencies: [{ code: 'USD', name: 'US Dollar', symbol: '$' }, ...], count } covering 150+ ISO 4217 fiat currencies. Does NOT include cryptocurrencies. Cheap to call (cached 24h upstream) —

AllRatesToday MCP Server — @allratestoday/mcp-server

English | 简体中文

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 — 150+ ISO 4217 currencies, refreshed every ~60 seconds from institutional interbank data
  • 📈 Historical series built in — 1d / 7d / 30d / 1y windows with sensible granularity per period
  • 🧰 Four focused tools — getexchangerate, gethistoricalrates, getratesauthenticated, list_currencies; 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 the open ECB reference table; 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

⚖️ Mid-market vs official central-bank rates

Everything this server returns is a mid-market rate: the live interbank midpoint, refreshed every ~60 seconds — the right number for price display, conversion, and anything that should track the market. It is not the official rate a tax authority or auditor may require. For those, AllRatesToday also serves published central-bank and tax-authority rates (100+ sources — ECB, Fed, HMRC, US Treasury, …) that are fixed once published and carry the institution's own publication date — via the central bank REST API and per-bank npm SDKs. The two can diverge by several percent, so pick by use case, not convenience.

🔓 Keyless mode — what works with no setup

Install it with no configuration at all and it starts, connects, and answers:

The keyless path reads the open, edge-cached /api/open/central-bank/ecb endpoint — no upstream cost, no rate limit to trip over, nothing to sign up for.
