Let Claude Code, Codex or Cursor use your real Chrome, logged in as you. One prompt to set up. Open source, MIT.
Browser Harness connects a language model to a real browser through an editable CDP WebSocket, allowing the agent to perform browser tasks and create reusable helpers when needed. Developers and browser agents use it for browser automation, with an MCP server available for compatible clients. The catalogue entries provide setup instructions and teach coding agents its browser workflow.
This repository also configures its own agents. See what browser-harness tells them →
