Automate the browser. Step in when needed.
Browser Core connects a browser to ChatGPT through a user-authorized MCP service. Run a browser on your own computer or on an isolated personal worker, inspect pages, fill forms, and pause to complete a login or CAPTCHA yourself.
What the beta can do
- Connect only Chrome tabs you explicitly approve, or start a separate Chromium profile.
- Read page text and accessible controls, navigate and interact with ordinary web forms.
- Allow you to take over a live session for a password, 2FA, or other manual step; then resume.
- Store a browser profile encrypted on the selected personal worker.
Manual control: for login and verification only
The remote handoff screen is intended for short manual steps: entering passwords, completing CAPTCHA, confirming 2FA/OAuth, or correcting an occasional field. It is not meant for comfortable extended browsing or working on complex websites.
For normal browser work, use Browser Core Local on your own computer. The agent can work with explicitly approved Chrome tabs, and you can use the real desktop browser directly without streaming a remote screen. If the agent runs on a BYO server, use manual handoff only when intervention is required and press “Done” to let the agent continue.
Download the free Mac beta
Version 0.7.8-beta — limited-access preview for local Mac users. Python 3.10–3.13 is required. This package is unsigned and not Apple-notarized; review the security requirements before installing.

Where Browser Core fits
Local Chrome: explicitly grant the browser tab you want an agent to use, without sending your entire Chrome profile to a hosted browser.
Personal VPS: run a separate Chromium worker on your own Linux server and connect it to ChatGPT through MCP.
Human takeover: let the agent pause while you complete a password, CAPTCHA or 2FA challenge in the same browser context, then resume automation.
Browserbase and other services also support human takeover. TinyFish provides managed hosting and proxies; Browser Core's current distinction is the choice of existing local Chrome or your own Linux worker. We do not claim comparable managed-cloud scale.

Current availability
Private technical testing only. Mac Local and a single-tenant BYO worker are being validated. Multi-user Cloud hosting, public signup, paid services and service-level guarantees are not available yet.
Existing users: connect your own approved device through the private Browser Core MCP. No access to other tabs or browser credentials is granted automatically.
