SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Provides real-browser visibility into UI behavior, enabling debugging and verification of UI components by inspecting the live DOM, console, and network activity.

Core Features & Use Cases

  • Live browser observation: inspect DOM, read console logs, analyze network requests, and profile performance using Chrome DevTools MCP.
  • UI debugging and verification: diagnose layout, interaction, and rendering issues against real runtime data across pages and components.
  • Use Case: When you need to reproduce a flaky UI bug, load the page in a real browser, capture console errors, network timing, and a DOM snapshot, then verify the fix.

Quick Start

Launch the MCP-enabled browser testing session by loading the target page and enabling DevTools MCP.
