Tests in real browsers. Use when building or debugging anything that runs in a browser. Use when you need to inspect the DOM, capture console errors, analyze network requests, profile performance, or verify visual output with real runtime data via Chrome DevTools MCP.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Browser Testing with DevTools

## Overview

Use Chrome DevTools MCP to give your agent eyes into the browser. This bridges the gap between static code analysis and live browser execution — the agent can see what the user sees, inspect the DOM, read console logs, analyze network requests, and capture performance data. Instead of guessing what's happening at runtime, verify it.

## When to Use

- Building or modifying anything that renders in a browser
- Debugging UI issues (layout, styling, interaction)
- Diagnosing console errors or warnings
- Analyzing network requests and API responses
- Profiling performance (Core Web Vitals, paint timing, layout shifts)
- Verifying that a fix actually works in the browser
- Automated UI testing through the agent

**When NOT to use:** Backend-only changes, CLI tools, or code that doesn't run in a browser.

## Setting Up Chrome DevTools MCP

### Installation

```bash
# Add Chrome DevTools MCP server to your Claude Code config
# In your project's .mcp.json or Claude Code settings:
{
  "mcpServers": {
    "chrome-devtools": {
      "command": "npx",
      "args": ["@anthropic/chrome-devtools-mcp@latest"]
    }
  }
}
```
