Browser Harness

Browser Harness connects an AI agent directly to Chrome or a Browser Use cloud browser through a thin CDP harness. It is useful when an agent needs real browser state, authenticated sessions, file uploads, debugging, scraping, QA, or site-specific workflows that can improve over repeated runs.

What you can do

  • Use a real browser: Connect to an existing Chrome profile with cookies and logged-in state.
  • Automate messy workflows: Let the agent inspect pages, click, type, upload files, handle tabs, and recover from missing helpers.
  • Build reusable helpers: Keep task-specific logic in agent-workspace/agent_helpers.py and optional domain skills.
  • Run local or cloud browsers: Use local Chrome for watched tasks, or Browser Use cloud when you need isolated/headless sessions.

Windows Setup

The RAPR skill installs immediately. The installer can clone Browser Harness and install the browser-harness command when Git and uv are available. Connecting to your real Chrome browser still requires user consent.

$dest = Join-Path $env:USERPROFILE "Developer\browser-harness"
git clone https://github.com/browser-use/browser-harness $dest
cd $dest
uv tool install -e .
browser-harness --doctor

Then open chrome://inspect/#remote-debugging in Chrome and allow remote debugging for the profile you want the agent to use.

Example Requests

  • "Use Browser Harness to log into my dashboard and export the latest report."
  • "Run a browser QA pass against localhost and fix any obvious UI breakage."
  • "Automate this multi-step website workflow using my existing Chrome session."

Only connect to accounts and sites the user authorizes. Prefer a separate browser profile for sensitive tasks, and do not silently operate on logged-in accounts.
