Yes, although MicroPython is focused on running on microcontrollers it can be useful if you want to reduce memory consumption, flash space and even startup time on servers.

The challenge is that MicroPython has many fewer standard libraries:

And so many Python libraries targeting CPython won't work out-of-the box and you'll need to modify them or use alternatives that do work on the MicroPython subset.
