mini-browser (mb) — Browser CLI for Agents

mb is a browser CLI where each command is a small Unix tool. It talks to Chrome over CDP (port 9222) via puppeteer-core.

Setup (only if not already available)

Setup is only needed when mb is not installed or Chrome is not reachable.
Run these checks first — if both pass, skip straight to the Command Reference.

Check if ready

# 1. Is mb installed?
which mb && echo "mb: ok" || echo "mb: MISSING"

# 2. Is Chrome listening on CDP?
curl -sf http://127.0.0.1:9222/json/version > /dev/null && echo "chrome: ok" || echo "chrome: NOT RUNNING"
