This server turns your AI coding assistant into a full-stack development companion by bridging the gap between terminal and browser. It spins up proxy servers that inject debugging tools into your web apps, letting your agent capture screenshots, inspect DOM elements, analyze network traffic, and receive JavaScript errors in real time. The floating browser overlay lets you sketch wireframes directly on running UIs or send messages to your agent without context switching. It wraps development processes and manages server lifecycles through MCP tools, handles both stdio transport for Claude Desktop and experimental channel mode for push events, and includes process management for coordinating multiple dev servers. Built for vibe coding sessions where your agent needs to see what you see and respond to visual feedback, not just edit files.
