Agent Browser Gateway is a Chrome extension designed to enhance browser-assisted development by allowing users to share specific tabs with local AI coding agents. This tool prioritizes user control by enabling per-tab consent, ensuring that no broad access is granted to the entire browser. Users can explicitly share a single tab, which then allows the local AI agent to perform various operations such as reading, screenshotting, and inspecting the console or network context, all while maintaining the user's existing session context.

The extension is built with privacy and efficiency in mind, featuring no host permissions and a local gateway over loopback transport. It supports various AI agents through an agent-agnostic CLI, optimizing Markdown reads to minimize unnecessary HTML noise. Additionally, Agent Browser Gateway maintains a local audit log for transparency in operations, ensuring no analytics or advertising identifiers are utilized, making it a secure option for developers looking to integrate AI into their workflows.
