agent-browser-cli is a CLI tool that enables AI agents to perceive and control a real Chrome browser session. It consists of a Rust CLI that communicates with a local daemon via HTTP API, which in turn communicates with a Chrome extension via WebSocket. The system preserves the user's login state and cookies while providing capabilities like tab management, page inspection, JavaScript execution, screenshots, and CDP access. The architecture cleanly separates concerns: the CLI handles user input, the daemon manages persistent connections, and the extension executes commands in the browser context.
