Official Model Context Protocol server for the Frankfurter exchange-rate API. A thin, stateless proxy over Frankfurter's v2 blended multi-source reference rates.
convert — the primary tool. Convert an amount between two currencies;
returns a money object { amount, currency } rounded to the target's minor
units. Pass date for a historical rate.get_rates — blended reference rates for the latest day or a single
date. Optional base and quotes. The raw-rate companion to convert.list_currencies — supported ISO 4217 codes and names as { code: name }.For time series, historical ranges, provider-specific rates, or bulk queries,
use the REST API at https://api.frankfurter.dev/v2 directly.
Rates are daily reference rates, not real-time trading rates. Not financial advice.
Docker:
The prebuilt ghcr.io/lineofflight/frankfurter-mcp:latest image is published
on each release; building from source also works.
Point any MCP client at http://<host>:3000/ (Streamable HTTP). The hosted
server is at https://mcp.frankfurter.dev/.
PORT — HTTP port (default 3000).FRANKFURTER_API_URL — upstream API base (default https://api.frankfurter.dev).
Set this to a self-hosted Frankfurter instance if desired. The value must be a
host root: any path prefix in it is discarded (e.g. https://example.com/api
resolves to https://example.com/v2/rates), so a self-hosted instance must be
reachable at the host root.MIT
