🔍 Console Monitoring Features

The key advantage of this MCP server is automatic console capture:

• Automatic Error Detection - Captures all JavaScript errors and unhandled Promise rejections
• Detailed Error Reports - Returns specific error messages with stack traces
• Real-time Monitoring - Console logs are captured as pages execute
• Comprehensive Coverage - Monitors console.log, console.error, console.warn, console.info

Example error report:

Task completed. Found console errors:
- TypeError: Cannot read properties of undefined (reading 'data') at app.js:45
- Unhandled Promise rejection: API timeout at fetch.js:89

🛠️ Troubleshooting

Browser not opening?

• The server auto-detects Playwright browsers
• First run may download Chromium automatically
• Check PLAYWRIGHT_BROWSERS_PATH environment variable

API key issues?

• Ensure your API key is valid and has credits
• OpenRouter users: Check your balance at openrouter.ai
• Try testing with a simple task first

Console logs not showing?

• Console capture is automatic but viewing requires explicit checking
• The agent will check console when task mentions "debug", "test", or "errors"
