Automate a real Google Chrome instance via the Chrome DevTools Protocol (CDP) and control it with `agent-browser --cdp PORT` for headed web workflows (login + navigation + screenshots + extraction) while keeping your normal Chrome profiles safe using `--user-data-dir` isolation. Use when agent-browser says “Browser not launched”, when you need a stable headed browser session, or when you want repeatable, low-frequency website automation without any risk-control bypass (captcha/fingerprinting evasion).
