A developer utility CLI written in Rust. 28 subcommands covering text processing, encoding, hashing, date math, file ops, networking, database connectivity, and more — with automatic module discovery and clipboard integration.
AI coding agents and developers repeatedly perform the same small operations — encoding, hashing, formatting, converting. ms puts them all behind one binary with zero startup cost.
