Perplexity

Convert Units with Unit & FX Calculator MCP Server

The `convert_unit` tool deterministically converts physical measurements. You feed it a value, source unit, and target unit; it gives you the correct result—no guesswork needed. Cascade uses this to solve things like converting miles per hour to kilometers per second when building complex data models.

Get Live Exchange Rates with MCP Server

Need to know how much money one currency is worth against another? The `get_rate` tool pulls the exact foreign exchange rate from the Frankfurter API. It caches results for an hour, so it doesn't hit the same endpoint repeatedly. This means your autonomous agent can calculate cross-border costs accurately without needing manual inputs.

Batch Convert Multiple Units with MCP Server

The `batch_convert` tool handles multiple physical unit conversions in a single, deterministic pass. You pass it an array of values along with their source and target units. It's perfect for when your goal requires converting dozens of different measurements at once. Cascade executes this whole sequence automatically.

Common questions about Unit & FX Calculator MCP in Windsurf

It eliminates hallucinated rates and mixed units, which is a huge headache. When you set a goal in Windsurf, Cascade knows it needs to use `convert_unit` or `get_rate` for accurate results.

Yeah, you can. The `batch_convert` tool lets you pass several different unit conversions at once. Cascade handles the multi-step execution without you having to prompt for every single change.

Absolutely. The `get_rate` tool pulls real, live exchange rates when your agent needs them. This keeps your calculations accurate whether you're working on a global dashboard or local data.

Yes. All conversions are deterministic, meaning given the same inputs and source units, it always returns the exact mathematical result. You never get a fuzzy estimate here.

It primarily works with physical unit values (like km/h or Celsius) and currency exchange rates, which are both numerical strings. It never touches user credentials.
