Mattermost CLI for humans and agents. TypeScript port of rhnvrm/mattermost-cli.

Install

Published on npm as @hieptuanle/mm-cli. Pick whichever fits your environment:

# Run without installing (no PATH changes)
npx @hieptuanle/mm-cli --help

# Global install — adds `mm` to your PATH
npm i -g @hieptuanle/mm-cli
pnpm add -g @hieptuanle/mm-cli

# Or install per-project
pnpm add @hieptuanle/mm-cli
npx mm --help

Once installed, the binary is mm:

mm --help

# Optionally expose `mm` globally:
pnpm link --global
