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.

LangChain's ecosystem of 500+ components combines seamlessly with Unit & FX Calculator through native MCP adapters. Connect 3 tools via Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures. with LangSmith tracing giving full visibility into every tool call, latency, and token cost.

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 LangChain in under two minutes — credentials fully managed, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

All 3 Unit & FX Calculator tools available for LangChain
