If the repo was structured as a package e.g. with project.toml and such there would be an even faster one-liner with pipx (https://pipx.pypa.io/latest/):

> pipx install git+https://github.com/Maciek-roboblog/Claude-Code-Usage-Monitor

> ccusage_monitor

I think there is a similar command for uv; uvx? Although, I am not sure if uvx has the same functionality / purpose as pipx.
