exchange-rates-mcp-server
If you need FX data inside an agent or MCP client without wrangling an API key, this server wraps the Frankfurter v1 API, which serves ECB daily reference rates. It exposes eight tools: list currencies, get a full rate snapshot for a base currency, get a single pair rate, convert an amount, pull a historical time series over a date range, and run read-only SQL against staged series through an embedded DuckDB layer. Point-in-time lookups go back to 1999-01-04, and retired currencies are available on dates where they had observations. Results come with the actual rate date, so weekend and holiday requests show when they snapped to the prior business day. It runs over stdio or streamable HTTP, and there's a hosted instance if you'd rather not run it yourself. Reach for it when you want an assistant to reason about currency conversions or historical rate movements with verifiable dates attached.
