Dev Browser

About

Dev Browser serves as a crucial bridge for AI agents, like those powered by OpenCode, to interact with local Chrome/Chromium browser tabs in real-time. It achieves this by acting as a Model Context Protocol (MCP) server that translates commands into Chrome DevTools Protocol (CDP) messages, facilitated by a lightweight browser extension and a local relay. This innovative architecture eliminates the need for Chrome's `--remote-debugging-port`, allowing agents to click, type, navigate, and capture screenshots within existing local browser sessions, providing AI-friendly DOM snapshots for smarter interactions.
