Browser Control

mcp_playwright_browser_navigate(url)          # Navigate to any URL
mcp_playwright_browser_click(element, ref)    # Click elements with AI guidance
mcp_playwright_browser_type(element, ref, text) # Type into form fields
mcp_playwright_browser_hover(element, ref)    # Hover interactions

Visual & Analysis

mcp_playwright_browser_take_screenshot(filename) # Capture screenshots
mcp_playwright_browser_snapshot()               # Get semantic DOM structure
mcp_playwright_browser_generate_playwright_test() # AI test generation

Advanced Features

mcp_playwright_browser_tab_new()               # Multi-tab testing
mcp_playwright_browser_wait_for()              # Smart waiting
mcp_playwright_browser_console_messages()      # Debug information

🚀 Demonstrated Functionality

Example: AI-Powered Test Workflow

Test Scenario: "Example Domain Navigation Test"
Steps Executed:
  1. ✅ Navigate to https://example.com
  2. ✅ Verify page title: "Example Domain"
  3. ✅ Identify semantic elements (heading, paragraphs, links)
  4. ✅ Click "More information..." link
  5. ✅ Navigate to IANA documentation page
  6. ✅ Capture screenshots for visual regression
  7. ✅ Extract full page structure with 80+ semantic elements
