Blended exchange rates from 50+ institutions via Frankfurter. Tools: get_rates, convert.
Connect Frankfurter to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Blended exchange rates from 50+ institutions via Frankfurter. Tools: get_rates, convert. The frankfurter mcp server is what makes that connection.
For time series, historical ranges, provider-specific rates, or bulk queries, use the REST API at https://api.frankfurter.dev/v2 directly.
Configuration is passed through the environment: FRANKFURTER_API_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. It is maintained by lineofflight; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Frankfurter's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
