Recipe: Get live currency exchange rates via exchange-rate-mcp
Server: [email protected] (npm) Transport: stdio Launch: npx -y [email protected] Auth: none — fully credential-free (uses Frankfurter API backed by ECB, no key needed) Tools: 1 (get_exchange_rate)
Tool: get_exchange_rate
Returns the current exchange rate between any two supported currencies. Data sourced from the European Central Bank via the Frankfurter API.
Input schema:
{
"from": "string (required) — source currency code, e.g. 'USD'",
"to": "string (required) — target currency code, e.g. 'EUR'"
}Output: A text string like "The current rate from USD to EUR is 0.86663 (Source: Frankfurter/ECB)"
When to use
- Agent comparing prices across markets (e.g. "is this cheaper in the US or UK store?")
- Travel budget estimation ("how much is €500 in TRY?")
- Financial reporting where current FX rates matter
- Any agent workflow that needs to normalize costs to a single currency
Gotchas
- ECB data updates once per business day — not suitable for intraday FX trading precision, but fine for general agent tasks.
- Returns a single rate per call. For batch conversions (USD to 10 currencies), you'll need 10 calls. No batch endpoint.
- Currency codes must be ISO 4217 (uppercase 3-letter). Passing "dollar" or "euro" won't work — use "USD", "EUR".
- Response is extremely compact (one sentence) — no historical data, no rate metadata, no spread/bid/ask.
