MCP Server Playwright Features

Key Features: Why This Tool is the MVP of Automation

  • Screenshot Samurai: Capture pages with precision like you’re framing a masterpiece. Full-page, element-specific, or even animated GIFs—because sometimes a picture is worth a thousand clicks.
  • Form Filler Pro: Tired of typing "John Doe" into every test form? Let MCP auto-populate fields so fast, you’ll question if it’s reading your mind.
  • JavaScript Ninja Mode: Inject custom scripts mid-navigation to manipulate pages in ways that’ll make your coworkers ask, "Did you hack the Matrix?"
  • Headless or Visible: Run in stealth mode (no browser window) for server bliss, or keep it visible so you can watch the automation show unfold.

Use Cases: Where MCP Shines Bright

Need examples? Here are scenarios where MCP becomes your new BFF:

  • Smoke Testing: Validate your app’s core functions after deployments without lifting a finger.
  • Content Harvesting: Extract data from websites that don’t play nice with APIs (looking at you, legacy systems).
  • Documentation Hero: Automatically screenshot UI changes for a living style guide that’s always up-to-date.
  • CI/CD Sidekick: Integrate into pipelines to run automated tests whenever code is pushed—because who wants to babysit builds?

MCP Server Playwright FAQ

FAQ: Answers to Questions You’ll Definitely Have

  • “Why am I seeing a ‘Cannot find module’ error?” Double-check that you’ve installed the package globally or added it to your project’s devDependencies.
  • “Where’s the config file stored?” By default, it lives in your project root. But feel free to relocate it—just update the path in your script!
  • “Can I automate multiple browsers?” Absolutely! Configure Chrome, Firefox, or even Safari in your setup. Cross-browser validation—served.
  • “How do I debug a failed script?” Add --verbose to your command line to see detailed logs. Sometimes the problem is as simple as a typo in a selector—human error strikes again.
