MTool Review

Review

MTool is a lightweight terminal-based tool manager that sits between you and your command-line tools. Think of it as a smart wrapper that remembers your most-used commands, suggests alternatives, and keeps your terminal clean from clutter.

What Is MTool?

MTool is a command-line interface that indexes your system's tools and provides an interactive menu to run them. Instead of memorizing commands or searching for them, you just:

Launch MTool
Type the first few letters of what you need
Select from fuzzy-matched results
The tool runs with the right arguments

It's not a replacement for your shell — it's an accelerator for common tasks.
