Cursor browser | Browser Harness
Let Cursoruse your browser.
Cursor's agent clicks, types and reads pages in your own Chrome, logged in as you.
When a tool is missing,
the agent writes it.
- agent: wants to pick a date
- agent_helpers.py → helper missing
- agent writes itagent_helpers.py + pick_date()
- date picked
Questions
How is it different from Cursor's built-in browser?
It is your real Chrome, with your tabs, cookies and logins, so Cursor can work on sites you are signed in to.
How do I set it up?
Pick Cursor in the menu. It opens Cursor with the setup prompt typed in. Send it, and Chrome asks once for permission.
What does it cost?
Nothing. Browser Harness is open source under MIT, and using your own Chrome is free. Cloud browsers are $0.02 per browser-hour if you want them.
You will never use
the browser again.
