LeenaShaw demonstrates how to integrate Playwright with the Model Context Protocol (MCP) in VS Code, empowering developers to automate tests using AI-powered workflows and natural language prompts.

Integrating Playwright MCP for AI-Driven Test Automation in VS Code

Introduction

Test automation is rapidly evolving, moving from basic scripted sequences to self-healing and now AI-powered workflows. With Model Context Protocol (MCP), Playwright can interact with AI models and external tools, facilitating intelligent test generation and adaptive debugging.

What Is Playwright MCP?

  • Playwright: Open-source web testing framework supporting Chromium, Firefox, and WebKit.
  • MCP (Model Context Protocol): Enables structured and secure communication between external tools (like Playwright) and AI models/services.

When MCP integrates with Playwright, teams gain:

  • AI-assisted test generation
  • Dynamic, real-time test data
  • Smarter debugging and adaptive workflows

Why Integrate MCP?

  • AI-powered test generation: Less manual scripting.
  • Dynamic context awareness: Tests respond to live data.
  • Enhanced debugging: AI suggests fixes.
  • Intelligent locator selection: AI helps pick robust selectors.
  • Natural language instructions: Write tests as simple prompts.

Getting Started in VS Code

Prerequisites

  • Node.js (v18.0.0+ recommended)
  • Playwright:
    • Install: npm install @playwright/test

Step-by-Step Setup

  1. Create Project Folder
    • mkdir playwrightMCP-demo && cd playwrightMCP-demo
  2. Initialize Playwright Project
    • npm init playwright@latest
  3. Install MCP Server for VS Code
    • Visit GitHub - microsoft/playwright-mcp and follow install instructions for VS Code.

    • In VS Code, search ‘>mcp’ to configure MCP. A mcp.json config is generated containing server details:

      {
  "servers": {
    "playwright": {
      "command": "npx",
      "args": ["@playwright/mcp@latest"],
      "type": "stdio"
    }
  },
  "inputs": []
}
    • Alternatively, install from GitHub MCP server registry via Extensions in VS Code.
    • Verify installation: In Copilot Chat, select Agent Mode, click Configure Tools, and confirm microsoft/playwright-mcp appears.
  4. Create AI-Assisted Test
    • Once MCP is set up, you can use prompts in Copilot Agent Mode to auto-generate Playwright tests.
    • Test Example:
      • Validate the ‘Frames’ documentation page navigation on Playwright Docs.
      • Prompt: “Create a Playwright automated test in JavaScript that verifies navigation to the ‘Frames’ documentation page, using robust locators to avoid errors.”
      • Steps:
        • Go to Playwright documentation
        • Select “Python” from the language dropdown
        • Enter “Frames” in the search box
        • Click the Frames documentation result
        • Verify the page heading is “Frames”
        • Log success or detailed failure
    • Copilot will generate a test and save it in your tests folder.
  5. Run Your Test
    • npx playwright test

Conclusion

Integrating Playwright MCP in VS Code empowers developers to build smarter, adaptive tests using AI, reducing manual effort and increasing test reliability. Start with basic scenarios and evolve your test automation strategy by leveraging AI-driven capabilities.

Note: Installation steps may vary by environment. Refer to MCP Registry · GitHub for the latest setup instructions.
