New tool lets AI agents drive your already-logged-in Chrome browser
Most tools spin up a fresh , which is a hassle when an agent needs to work with a SaaS dashboard, internal tool, or any page you're already signed into. Browser Relay connects AI agents such as Codex, Claude, Cursor, or a custom-built agent directly to the Chrome session you're already using, instead of launching a separate automation browser. Cookies, login state, localStorage, and installed extensions all stay intact.
It's offered three ways: a CLI, an MCP server, and a small HTTP API. It can run locally, or be reached remotely through an connection that doesn't require exposing a local port. The project is MIT licensed, written in plain JavaScript, and has only one runtime dependency.
It's on GitHub at reliefeai/browser-relay, and the creator is specifically looking for feedback on the , how it feels to use as an agent, and which real browser workflows still feel fragile.
