Convert Units with Unit & FX Calculator MCP Server

The `convert_unit` tool gives you deterministic physical conversions, perfect for automated testing. You pipe a value and units into the command line, and it spits out the exact conversion factor. This guarantees that any service check or unit test in your CI/CD pipeline uses verified math.

Get Live Exchange Rates with MCP Server

Need to validate cross-currency pricing in a shell script? Use `get_rate` to pull the exact foreign exchange rate. Since it caches for an hour, your cron job won't hammer the API unnecessarily. This makes running international financial checks reliable and efficient within any container environment.

Batch Convert Multiple Units with MCP Server

The `batch_convert` tool executes multiple unit conversions in one deterministic pass. This is ideal for pipeline scripts that process arrays of data, like weights or dimensions from a manifest file. You just run the command once and get all the required converted values back to pipe into your next script step.
