Summary
Exchange rates an assistant looks up rather than guesses.
Currency questions are exactly where a language model's training data goes stale silently. This connects the answer to Frankfurter's published rates — including rates on a chosen past date — with no key and no install.
What it is
A hosted MCP server for currency conversion and exchange rates, backed by the Frankfurter API. There is nothing to run: point a client at https://currency-mcp.wesbos.com.
What you get
- A direct conversion — amount, source currency, target currency, answer
- Today's rates against any base currency, optionally narrowed to the currencies you care about
- Historical rates for a specific date, so a past invoice or transaction can be valued as it stood then
- The full list of supported currency codes with their full names
- Two endpoints: `/mcp` for streamable HTTP and `/sse` for clients that still speak HTTP+SSE
Requirements
No account and no key — a single URL in your client config. Clients without streamable HTTP support can bridge to the `/sse` endpoint with npx mcp-remote.
Setup effort
One command — npx mcp-remote https://currency-mcp.wesbos.com/sse
