Summary

Major refactor implementing a modular command architecture for the Unreal MCP plugin, improving code organization, maintainability, and extensibility.

What's Changed

🏗️ Architecture Improvements

  • Implemented modular command structure with category-based organization
  • Separated concerns into Editor, Engine, and specialized command handlers
  • Added comprehensive error handling and validation across all modules

✨ New Features

  • Asset Management System: Complete asset lifecycle management (list, load, save, duplicate, delete, rename, import/export)
  • World/Level Management: Level creation, loading, streaming levels, and landscape tools
  • Enhanced Testing Framework: Comprehensive test suite with unit, integration, and validation tests
  • CI/CD Pipeline: GitHub Actions workflow for automated testing and validation

📁 Code Organization

  • Restructured C++ plugin into modular command handlers:
    • Editor/AssetTools: Asset registry, content browser operations
    • Editor/Landscape: Landscape creation and modification
    • Editor/LevelEditor: Level management and streaming
    • Engine/World: World context operations
  • Organized Python tools into category-based modules matching C++ structure
  • Added comprehensive test coverage with 100+ test cases

📚 Documentation

  • Added ARCHITECTURE.md documenting system design and communication flow
  • Created CLAUDE.md with coding standards and development guidelines
  • Added agent definitions for specialized Unreal development tasks
  • Included attribution and licensing information

🛠️ Developer Experience

  • Added pre-commit hooks for code quality
  • Created helper scripts for Windows development
  • Implemented comprehensive logging and debugging tools
  • Added test coverage reporting and validation scripts

Testing

  • ✅ All existing functionality preserved and tested
  • ✅ New test suite covers all command categories
  • ✅ Integration tests validate end-to-end workflows
  • ✅ Performance benchmarks ensure no regression

Breaking Changes

None - all existing APIs remain compatible

@jonathanhawkins
fix: Critical fixes for StaticMeshActor visibility and WSL2 connectivity
ef4fd10 
CORE FIXES ONLY:
1. StaticMeshActors now have mesh set (were invisible before)
2. Server binds to 0.0.0.0 instead of 127.0.0.1 (enables WSL2)
3. Python host/port configurable via env vars

These are minimal, essential changes that fix broken functionality.
@jonathanhawkins
docs: Add WSL2 setup documentation and helper scripts
0f926bc 
- StartUnrealWithMCP.bat for easy Windows launch with correct flags
- mcp-wsl2-example.json as reference configuration
- Clear documentation on when/why to use -UnrealMCPBind=0.0.0.0
- start_mcp.sh helper for WSL2 users

Documentation only - no code changes.
@jonathanhawkins
docs: Add screenshot tool documentation and MCP usage examples
fc2883a 
- Added screenshot capability to Editor Control features list
- Added Example MCP Usage section with natural language examples
- Clarified that actors now appear with meshes (fixing previous bug)
- Documented that screenshots use Unreal's built-in tool
@jonathanhawkins
fix: Remove hardcoded IP from start_mcp.sh
c48d136 
- Use environment variables with defaults instead of hardcoded IP
- Default to localhost (127.0.0.1) if UNREAL_HOST not set
- Add helpful echo messages showing connection target
- Make script more portable by using relative paths
@jonathanhawkins
feat: Add comprehensive feature roadmap
caaef7f 
- Analyzed 3 major unreal-mcp implementations
- Identified 60+ potential new features to add
- Created 6-phase implementation plan
- Covers materials, Niagara, animation, AI, physics, and more
- Incorporates best ideas from kvick-games, runreal, and ayeletstudioindia
