Could you build this?
Partial While an MCP server wrapper and Chrome extension UI are vibe-codeable, building a reliable, production-grade Chrome DevTools Protocol (CDP) orchestrator with live network manipulation, debugger integration, and multi-session synchronization requires complex systems engineering.
What it would actually take: The stack comprises a Chrome Extension (Manifest V3) communicating via Native Messaging or WebSockets to a local TypeScript daemon/MCP server, interfacing with Chrome's debugging port via CDP. The hardest elements are robust DOM accessibility tree snapshots, resilient locator diffing across dynamic SPAs, and handling CDP session lifecycle and frame attachments without crashing the browser. This requires deep familiarity with the Chrome DevTools Protocol specifications and browser automation internals.
