Playwright MCP Extension Repro

Minimal reproduction showing that standard Chrome extension loading in the Playwright MCP server fails without specific configuration settings.

Feature Request: microsoft/playwright#39569

🚀 Quick Start

  1. Install dependencies:

    npm install

  2. Run the matrix test:

    npm test

Related MCP server: mcp-playwright

📊 What this tests

The script repro_matrix.ts compares two configurations:

  1. ADVANCED_CONFIG: Uses the specific settings identified to enable extensions:

    • channel: "" (Reverts to bundled Chromium)

    • chromiumSandbox: false (Allows unpacked extension mounting)

    • allowUnrestrictedFileAccess: true (Disables protocol guard)

  2. PAVEL_SUGGESTION: Uses the simplified configuration suggested in the feature request.

✅ Success Criteria

  • Background Color: The extension should inject a content script that turns example.com pink (rgb(255, 192, 203)).

  • Page Title: The extension should change the document title to PINK_EXT_ACTIVE.
