* Add a decorate that wraps around the `mcp.tool` decorator.
This will allow us to more easily collect tools
* Register tools that's defined in the tools folder
* Update Python tools to use new decorator
* Convert script_apply_edits tool
* Convert last remaining tools with new decorator
* Create an attribute so we can identify tools via Reflection
* Add attribute to all C# tools
* Use reflection to load tools
* Initialize command registry to load tools at startup
* Update tests
* Move Dev docs to docs folder
* Add docs for adding custom tools
* Update function docs for Python decorator
* Add working example of adding a screenshot tool
* docs: update relative links in README files
Updated the relative links in both README-DEV.md and README-DEV-zh.md to use direct filenames instead of paths relative to the docs directory, improving link correctness when files are accessed from the root directory.
* docs: update telemetry documentation path reference
Updated the link to TELEMETRY.md in README.md to point to the new docs/ directory location to ensure users can access the telemetry documentation correctly. Also moved the TELEMETRY.md file to the docs/ directory as part of the documentation restructuring.
* rename CursorHelp.md to docs/CURSOR_HELP.md
Moved the CursorHelp.md file to the docs directory to better organize documentation files and improve project structure.
* docs: update CUSTOM_TOOLS.md with improved tool naming documentation and path corrections
- Clarified that the `name` argument in `@mcp_for_unity_tool` decorator is optional and defaults to the function name
- Added documentation about using all FastMCP `mcp.tool` function decorator options
- Updated class naming documentation to mention snake_case conversion by default
- Corrected Python file path from `tools/screenshot_tool.py` to `UnityMcpServer~/src/tools/screenshot_tool.py`
- Enhanced documentation for tool discovery and usage examples
* docs: restructure development documentation and add custom tools guide
Rearranged the development section in README.md to better organize the documentation flow. Added a dedicated section for "Adding Custom Tools" with a link to the new CUSTOM_TOOLS.md file, and renamed the previous "For Developers" section to "Contributing to the Project" to better reflect its content. This improves discoverability and organization of the development setup documentation.
* docs: update developer documentation and add README links
- Added links to developer READMEs in CUSTOM_TOOLS.md to guide users to the appropriate documentation
- Fixed typo in README-DEV.md ("roote" → "root") for improved clarity
- These changes improve the developer experience by providing better documentation navigation and correcting technical inaccuracies
* feat(tools): enhance tool registration with wrapped function assignment
Updated the tool registration process to properly chain the mcp.tool decorator and telemetry wrapper, ensuring the wrapped function is correctly assigned to tool_info['func'] for proper tool execution and telemetry tracking. This change improves the reliability of tool registration and monitoring.
* Remove AI generated code that was never used...
* feat: Rebuild MCP server installation with embedded source
Refactored the server repair logic to implement a full rebuild of the MCP server installation using the embedded source. The new RebuildMcpServer method now:
- Uses embedded server source instead of attempting repair of existing installation
- Deletes the entire existing server directory before re-copying
- Handles UV process cleanup for the target path
- Simplifies the installation flow by removing the complex Python environment repair logic
- Maintains the same installation behavior but with a cleaner, more reliable rebuild approach
This change improves reliability of server installations by ensuring a clean slate rebuild rather than attempting to repair potentially corrupted environments.
* Add the rebuild server step
* docs: clarify tool description field requirements and client compatibility
* fix: move initialization flag after tool discovery to prevent race conditions
* refactor: remove redundant TryParseVersion overrides in platform detectors
* refactor: remove duplicate UV validation code from platform detectors
* Update UnityMcpBridge/Editor/Tools/CommandRegistry.cs

* refactor: remove unused UnityEngine references from menu item classes
* Add new tools to manage a prefab, particularly, making them staged.
This might be enough, but it's possible we may have to extract some logic from ManageGameObject
* feat: add AssetPathUtility for asset path normalization and update references in ManageAsset and ManagePrefabs
* feat: add prefab management tools and register them with the MCP server
* feat: update prefab management commands to use 'prefabPath' and add 'create_from_gameobject' action
* fix: update parameter references to 'prefabPath' in ManagePrefabs and manage_prefabs tools
* fix: clarify error message for missing 'prefabPath' in create_from_gameobject command
* fix: ensure pull request triggers for unity tests workflow
* Revert "fix: ensure pull request triggers for unity tests workflow"
This reverts commit 10bfe54b5b7f3c449852b1bf1bb72f498289a1a0.
* Remove delayed execution of executing menu item, fixing #279
This brings the Unity window into focus but that seems to be a better UX for devs.
Also streamline manage_menu_item tool info, as FastMCP recommends
* docs: clarify menu item tool description with guidance to use list action first
* feat: add version update for server_version.txt in bump-version workflow
* fix: simplify error message for failed menu item execution
Performance & Quality Improvements:
- Add shared JsonSerializer to eliminate per-call allocation overhead
- Optimize ComponentResolver with CacheByName for short-name lookups
- Deduplicate Vector3 parsing implementations to reduce maintenance burden
- Improve property name normalization for better fuzzy matching quality
- Reduce log noise by avoiding duplicate component resolution warnings
Code Quality:
- Keep using static import for ComponentResolver (CodeRabbit was incorrect about this)
- Normalize property names consistently in AI suggestions algorithm
- Remove duplicate ParseVector3 implementation
TestAsmdef Fix:
- Revert TestAsmdef back to runtime-compatible (remove "includePlatforms": ["Editor"])
- CustomComponent now works correctly for asmdef testing as originally intended
- Validates that ComponentResolver properly handles both short and FQN for asmdef components
Live Testing Validation:
- All ComponentResolver functionality verified through live MCP connection
- AI property matching working perfectly with natural language input
- Assembly definition support fully functional for both default and custom assemblies
- Error handling provides helpful suggestions and complete context
All 45 C# tests + 31 Python tests still passing. Production ready!

Add support for creating physics material assets. Works on Unity 2022 onwards and Unity 6, since they use different naming for PhysicsMaterial(PhysicMaterial before Unity 6, and PhysicsMaterial after).
Add naming examples on the server side
TODO: currently unity-mcp only support adding gameobject and specifying adding a physic material, and manage_gameobject.cs does not handle a detailed request such as the copied request well. Will be the future work.
Example:
{
`name`: `BouncyCube`,
`action`: `create`,
`position`: [
6,
2,
0
],
`primitive_type`: `Cube`,
`components_to_add`: [
`Rigidbody`
],
`component_properties`: {
`Rigidbody`: {
`mass`: 1,
`useGravity`: true
},
`BoxCollider`: {
`material`: `Assets/Physics Materials/SuperBouncePhysicsMaterial.physicmaterial`
}
}
}
1. Solve the IDE/Unity miscommunication for the _Color and menuPath params
2. TODOs: Fix readme, look into more issues, bring back tool dev tutorial, view pull request and set a future roadmap
