No Extensions Allowed: The Chrome DevTools MCP Dilemma

Chrome DevTools MCP is a game-changer for AI coding assistants like GitHub Copilot and Cursor—it lets them see what your code actually does in the browser, debug console errors, and validate UI in real-time.Problem: The spawned Chrome instance doesn't support extensions, so there's no way to attach auth cookies/headers when connecting to staging APIs. This blocks you from using Chrome DevTools MCP with authenticated apps.I built a simple Express proxy that solves this. Route your API calls through it, and it automatically attaches your auth credentials (cookies, bearer tokens, custom headers) to requests going to your staging environment.Setup takes 5 minutes. Now your AI assistant can debug your actual authenticated app with full Chrome DevTools capabilities.GitHub: https://github.com/vsanse/proxy-node
