SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Tests in real browsers via Chrome DevTools MCP to give your agent eyes into the browser, enabling live inspection of the DOM, console logs, network activity, and performance data to debug UI issues.

Core Features & Use Cases

  • DOM Inspection and live state checks
  • Console Logs capture (info, warnings, errors)
  • Network Monitor for requests/responses
  • Performance Profiling and timing analysis
  • Visual verification with real runtime data

Quick Start

Run the MCP Chrome DevTools server and connect your agent to a running browser to begin live debugging.

Frequently Asked Questions about browser-testing-with-devtools

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I debug UI rendering issues using live browser data?▼

Debug UI rendering issues by inspecting the live DOM, capturing console logs, and monitoring network activity. This connects your automated agent to a real browser session to surface runtime data for layout bugs and rendering discrepancies.

Can I capture network requests and console errors during automated browser testing?▼

Yes, you can capture network requests and console errors during automated browser testing. The tool monitors network traffic for requests and responses while logging console info, warnings, and errors directly from the active browser session.

How does DOM inspection work with an automated agent?▼

DOM inspection with an automated agent works by establishing a live connection to a running browser via Chrome DevTools MCP. This allows the agent to observe and interact with real browser rendering to check live DOM state and verify UI elements.

Do I need a Chrome DevTools MCP server to inspect real browsers?▼

Yes, you need a Chrome DevTools MCP server configured in your project and an active browser session. This setup is required to establish the live connection needed to surface browser-origin data to your agent.

What's the best way to profile web application performance during UI debugging?▼

Profile web application performance during UI debugging by running the Chrome DevTools MCP server and connecting your agent. This enables performance profiling and timing analysis using real runtime data from the active browser session.

Why does my automated agent fail to observe real browser rendering?▼

Your automated agent fails to observe real browser rendering if the Chrome DevTools MCP server is not configured or an active browser session is missing. Both prerequisites must be met to establish a live connection and surface browser-origin data.
