Ryan Malloy ab68039f2e roadmap: comprehensive 4-phase implementation plan for enhanced Playwright MCP features 
Phase 1: Enhanced Navigation & Control (5 tools - back/forward nav, resize, devices, offline)
Phase 2: Chrome Extension Management (expand beyond 9 extensions, auto-update, workflows)
Phase 3: Coordinate-Based Vision Tools (enhance existing mouse tools, advanced patterns)
Phase 4: Real-World Testing & Polish (multi-client scenarios, UX refinement)

Next: Begin Phase 1 with browser_navigate_back implementation.
Current status: MCP client identification system complete and production-ready.

Comprehensive Implementation Roadmap

🎯 Priority Order Established

  1. Phase 1: Enhanced Navigation & Control (low complexity, broad utility)
  2. Phase 2: Chrome Extension Management Tools (medium complexity, high developer value)
  3. Phase 3: Coordinate-Based Vision Tools (medium complexity, advanced automation)
  4. Phase 4: Real-World Testing & Polish (production readiness discussion)

✅ Current Status

  • MCP Client Identification System: COMPLETE (5 tools implemented, tested, documented)
  • Feature Gap Analysis: COMPLETE (10 missing tools identified vs Python version)
  • Production Ready: Feature branch feature/mcp-client-debug-injection ready for merge

📋 Phase 1: Enhanced Navigation & Control (NEXT)

Missing Tools to Implement:

  1. browser_navigate_back - Browser back button functionality

    • Implementation: await page.goBack() with wait conditions
    • Schema: No parameters needed
    • Return: Page snapshot after navigation

  2. browser_navigate_forward - Browser forward button functionality

    • Implementation: await page.goForward() with wait conditions
    • Schema: No parameters needed
    • Return: Page snapshot after navigation

  3. browser_resize - Resize browser window

    • Implementation: await page.setViewportSize({ width, height })
    • Schema: width: number, height: number
    • Return: New viewport dimensions

  4. browser_list_devices - List device emulation profiles (ENHANCE EXISTING)

    • Current: Basic device listing exists in configure.ts
    • Enhancement: Add detailed device info, categorization
    • Schema: Optional category filter
    • Return: Structured device profiles with capabilities

  5. browser_set_offline - Toggle offline network mode

    • Implementation: await context.setOffline(boolean)
    • Schema: offline: boolean
    • Return: Network status confirmation

Implementation Location:

  • Add to /src/tools/navigate.ts (back/forward)
  • Add to /src/tools/configure.ts (resize, offline, devices)

📋 Phase 2: Chrome Extension Management

Current Extensions Available:

  • react-devtools, vue-devtools, redux-devtools, lighthouse, axe-devtools
  • colorzilla, json-viewer, web-developer, whatfont

Enhancement Tasks:

  1. Research extension installation patterns - Study popular dev extensions
  2. Add more popular extensions - Expand beyond current 9 options
  3. Extension auto-update - Version management and updates
  4. Management workflow tools - Bulk operations, profiles

📋 Phase 3: Coordinate-Based Vision Tools

Current Implementation:

  • Located: /src/tools/mouse.ts
  • Capability: vision (opt-in via --caps=vision)
  • Existing: browser_mouse_move_xy, browser_mouse_click_xy, browser_mouse_drag_xy

Enhancement Tasks:

  1. Review existing implementation - Audit current vision tools
  2. Enhance coordinate precision - Sub-pixel accuracy, scaling
  3. Advanced drag patterns - Multi-step drags, gesture recognition
  4. Integration helpers - Screenshot + coordinate tools

📋 Phase 4: Real-World Testing & Polish

Discussion Topics:

  1. Multi-client testing scenarios - Actual parallel usage
  2. Debug toolbar UX refinement - User feedback integration
  3. Performance optimization - Memory usage, injection speed
  4. Advanced identification features - Custom themes, animations

🛠️ Implementation Notes

Current Feature Branch:

  • Branch: feature/mcp-client-debug-injection
  • Files modified: 4 main files + 2 test files
  • New tools: 5 (debug toolbar + code injection)
  • Lines added: ~800 lines of TypeScript

Ready for Production:

  • All linting issues resolved
  • README updated with new tools
  • Comprehensive testing completed
  • Demo documentation created

Next Steps Before Context Loss:

  1. Begin Phase 1 with browser_navigate_back implementation
  2. Test navigation tools thoroughly
  3. Move to Phase 2 Chrome extensions
  4. Maintain momentum through systematic implementation

🎯 Success Metrics

  • Phase 1: 5 new navigation tools (bringing total to 61 tools)
  • Phase 2: Enhanced extension ecosystem (10+ popular extensions)
  • Phase 3: Advanced vision automation capabilities
  • Phase 4: Production-ready multi-client system

This roadmap ensures systematic progression from basic functionality to advanced features, maintaining the TypeScript Playwright MCP server as the most comprehensive implementation available.
