Browser Hands lets Codex and Cursor drive Chrome through MCP

On November 13, 2026, at 22:40, a developer posted an open-source tool called Browser Hands on V2EX. The author described being a heavy user of agents such as Claude Code, Codex, Hermes, and OpenClaw for tasks that required filling in web forms, working through admin panels, and looking up information, and said that browser control had been a frustrating area, so he spent several weekends building the tool and released it for community testing.

Browser Hands consists of a Chrome extension paired with a local MCP Server that runs on the user's machine. Packaged as a single JS file of roughly 450 KB, it does not require a cloud VM or a headless browser. Instead, it lets any agent that supports MCP take over the Chrome instance the user is already running, performing actions such as clicking, typing, reading pages, taking screenshots, executing JS, and recording GIFs. The author demonstrated an agent automatically filling out a Product Hunt submission form inside an already signed-in Chrome session, and noted that the tool can work alongside Codex, Cursor, and similar agents.

The author also explained why he did not adopt existing options, saying the solutions he tried each had drawbacks. Citing the official Claude / Codex Chrome extensions as an example, he said their experience is strong but tied to a single vendor and subscription, so other agents he uses regularly cannot benefit from the same level of support. As of the available material, the project has only been released for trial use, with no further developments reported.
