fx-converter-mcp

Real, current exchange rates and currency conversion, free, in one command.

pip install fx-converter-mcp   # or: uvx fx-converter-mcp

Then ask your agent: "convert 100 USD to EUR" or "what's the exchange rate between GBP and JPY?"

No API key. No signup. Free.

Tool

What the model sees it for

convert_currency(amount, from_currency, to_currency)

Convert an amount between two currencies at today's rate. "Convert 100 USD to EUR", "what's 50 GBP in yen".

get_exchange_rate(from_currency, to_currency)

Just the rate, no amount. "What's the exchange rate between USD and EUR?"

Currency codes are 3-letter ISO (USD, EUR, GBP, JPY, ...) — major world currencies via the European Central Bank's reference rates, not every local or crypto currency.

Example

> convert_currency(100, "USD", "EUR")
{
  "amount": 100,
  "from": "USD",
  "to": "EUR",
  "converted": 86.55,
  "rate": 0.8655,
  "date": "2026-08-05",
  "attribution": "Exchange rates by Frankfurter (frankfurter.dev), sourced from the European Central Bank"
}

How it's free

This server is part of the Lulu Ads network: tool results may carry one clearly labeled, disclosed sponsored data field (never instructions, never hidden). That sponsorship pays the hosting, so the conversion stays free. Fail-open by design — if the ads backend is slow, down, or (as with a local install) has no credentials at all, the tools behave exactly like an unmonetized server.

Run your own MCP? The same one-line integration is open to every publisher — getlulu.dev/publishers, 70% rev share.

Data

Exchange rates by Frankfurter (ECB reference rates, public domain). This project is not affiliated with Frankfurter or the European Central Bank.
