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)

Frequently asked questions
How often are currency rates updated?
Rates are fetched live and cached for exactly 1 hour.
What physical units are supported?
Length, mass, volume, temperature, and speed are fully supported via mathjs.
Can it batch convert an array of data?
Yes, the batch processor can handle large JSON arrays instantly.
How does Windsurf discover MCP tools?
Windsurf reads the mcp_config.json file on startup and connects to each configured server via Streamable HTTP. Tools are listed in the MCP panel and available to Cascade automatically.
Can Cascade chain multiple MCP tool calls?
Yes. Cascade is an agentic system. it can plan and execute multi-step workflows, calling several tools in sequence to accomplish complex tasks without manual prompting between steps.
Does Windsurf support multiple MCP servers?
Yes. Add as many servers as needed in mcp_config.json. Each server's tools appear in the MCP panel and Cascade can use tools from different servers in a single flow.
