- Replace Assembly.LoadFrom with already-loaded assembly search
- Prioritize Player assemblies over Editor assemblies using CompilationPipeline
- Support both short names and fully-qualified component names
- Add comprehensive caching and error handling with disambiguation
- Use Undo.AddComponent for proper editor integration
- Handle ReflectionTypeLoadException safely during type enumeration
- Add fallback to TypeCache for comprehensive type discovery in Editor
Fixes component resolution across custom assembly definitions and eliminates
"Could not load the file 'Assembly-CSharp-Editor'" errors.
Tested with:
- Built-in Unity components (Rigidbody, MeshRenderer, AudioSource)
- Custom user scripts in Assembly-CSharp (TicTacToe3D)
- Custom assembly definition components (TestNamespace.CustomComponent)
- Error handling for non-existent components

* refactor: rename namespace from UnityMcpBridge to MCPForUnity across all files
See thread in #6, we can't use Unity MCP because it violates their trademark.
That name makes us look affiliated. We can use MCP for Unity
* Change package display name, menu item and menu titles
These are front facing so has to change for Unity asset store review
* Misc name changes in logs and comments for better consistency
* chore: update editor window title from 'MCP Editor' to 'MCP for Unity'
* refactor: update branding from UNITY-MCP to MCP-FOR-UNITY across all log messages and warnings
* chore: rename Unity MCP to MCP For Unity across all files and bump version to 2.1.2
* docs: update restore script title to clarify Unity MCP naming
* Fix usage instructions
* chore: update log messages to use MCP For Unity branding instead of UnityMCP
* Add a README inside plugin, required for distributing via the asset store
* docs: update Unity port description and fix typo in troubleshooting section
* Address Rabbit feedback
* Update Editor prefs to use new name
Prevents overlap with other Unity MCPs, happy to revert if it's too much
* refactor: rename server logger and identifier from unity-mcp-server to mcp-for-unity-server
* Standardize casing of renamed project to "MCP for Unity", as it is on the asset store
* Remove unused folder
* refactor: rename Unity MCP to MCP for Unity across codebase
* Update dangling references
* docs: update product name from UnityMCP to MCP for Unity in README
* Update log and comments for new name
The Unity Editor was crashing with ValidTRS() assertions when attempting to get components from certain GameObjects like the Main Camera.
Investigation revealed the crash occurred during JSON serialization when reflection code accessed specific matrix properties (e.g., Camera.cullingMatrix, Transform.rotation, Transform.lossyScale). Accessing these properties appears to trigger internal Transform state validation failures, potentially due to interactions with the JSON serializer's reflection mechanism.
This fix addresses the issue by:
- Replacing LINQ iteration in GetComponentsFromTarget with a standard loop over a copied list to prevent potential premature serialization interactions.
- Explicitly skipping known problematic Camera matrix properties (cullingMatrix, pixelRect, rect) and generic matrix properties (worldToLocalMatrix, localToWorldMatrix) within GetComponentData's reflection logic.
- Retaining manual serialization for Transform component properties to avoid related reflection issues.
Moved serialization logic (GetGameObjectData, GetComponentData, metadata caching, JSON conversion helpers) from ManageGameObject tool to a dedicated GameObjectSerializer class in the Helpers namespace.
This improves separation of concerns and reduces the size/complexity of ManageGameObject.cs. Updated ManageGameObject to use the new helper class.
