What is the Unit & FX Calculator MCP Server?
LLMs notoriously struggle with complex compound conversions (e.g. converting km/h to mph with specific decimal rounding). Worse, they hallucinate foreign exchange (FX) rates based on their historical training data rather than current markets. This MCP bridges that gap.
The Superpowers
- Physical Determinism: Converts length, mass, volume, temperature, and speed using the exact mathematical engine of
mathjs. Completely eliminates metric/imperial hallucination. - Live FX Rates: Uses the Frankfurter API to fetch the latest European Central Bank reference rates for absolutely precise currency conversion.
- In-Memory Edge Cache: FX rates are cached in a native V8
Mapfor 1 hour, meaning massive batch conversions run instantly without getting rate-limited.
Built-in capabilities (3)
). Pass the value, source unit, and target unit for exact mathematical conversion. Converts multiple physical units in a single deterministic pass
Deterministically converts physical units (e.g. km/h to mph, celsius to fahrenheit)using mathjs
Gets the exact foreign exchange rate between two currencies using Frankfurter API (1h cache)
