Connects Claude Code, Codex or Cursor to the Chrome you already have open, logged in as you, so it can click, type, read and download on real sites, and writes its own helper for any step it can't do yet.

Short excerpt from the README of browser-use/browser-harness. Read the full README on GitHub.
Written by us so you can reuse it. Replace each [bracket] with your details.
The agent sees and can act in your whole logged-in browser: email, banking, social accounts. Use a separate Chrome profile with only the logins it needs, and watch the first runs. It sends anonymous usage data by default; set BH_TELEMETRY=0 to turn it off. Some site guides in the repo pipe an install script into a shell; read before running.
