About 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.

LlamaIndex agents combine Unit & FX Calculator tool responses with indexed documents for comprehensive, grounded answers. Connect 3 tools through Vinkius and query live data alongside vector stores and SQL databases in a single turn. ideal for hybrid search, data enrichment, and analytical workflows.

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 Map for 1 hour, meaning massive batch conversions run instantly without getting rate-limited.

The Unit & FX Calculator MCP Server exposes 3 tools through the Vinkius. Connect it to LlamaIndex in under two minutes — credentials fully managed, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
