Available tools 1

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

utility
utility_convert_units
Use this when you need to convert between measurement units. Returns the conversion result with formula in JSON. Returns: 1. result (converted value) 2. from and to units 3. inputValue 4. formula (human-readable conversion formula) 5. category (length/weight/temperature/volume/speed/data). Supports: length (m, km, mi, ft, in, cm, mm, yd), weight (kg, g, lb, oz, mg, ton), temperature (celsius, fahrenheit, kelvin), volume (l, ml, gal, qt, pt, cup, fl_oz), speed (m/s, km/h, mph, knots), data (B, KB, MB, GB, TB, PB). Example output: {"inputValue":100,"from":"km","to":"mi","result":62.1371,"formula":"100 km * 0.621371 = 62.1371 mi","category":"length"} Use this FOR unit conversions in calculations, data analysis, scientific computing, recipe scaling, and engineering applications. Do NOT use for currency conversion -- use finance_convert_currency instead. Do NOT use for timezone conversion -- use utility_convert_timezone instead. Do NOT use for stock prices -- use finance_get_stock_price instead.

Unit Converter API — questions

Answers built from our own checks of this server.

What can Unit Converter API do?
It exposes 1 tools, read directly from the server on our last check. Among them: utility_convert_units. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Unit Converter API working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 32 ms. The bar chart above shows every period we have measured.
How do I connect Unit Converter API?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Unit Converter API need an API key?
No. Unit Converter API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Unit Converter API?
It answers our handshake in 32 ms on average, which is faster than 99% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Unit Converter API open source?
Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
