* 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

- Improve user experience with clear instructions and accessible client management
* feat: add comprehensive dependency requirement warnings
- Add critical warnings throughout setup wizard that package cannot function without dependencies
- Update package.json description to clearly state manual dependency installation requirement
- Prevent setup completion if dependencies are missing
- Enhance skip setup warning to emphasize package will be non-functional
- Add error messages explaining consequences of missing dependencies
- Update menu item to indicate setup wizard is required
- Ensure users understand package is completely non-functional without proper dependency installation
* refactor: simplify setup wizard for production
BREAKING: Reduced setup wizard from 5 steps to 3 streamlined steps:
- Step 1: Setup (welcome + dependency check + installation guide)
- Step 2: Configure (client configuration with direct access to full settings)
- Step 3: Complete (final status and quick access to resources)
Simplifications:
- Consolidated UI components with DRY helper methods (DrawSectionTitle, DrawSuccessStatus, DrawErrorStatus)
- Simplified dependency status display with clean icons and essential info
- Removed complex state management - using simple EditorPrefs instead
- Removed unused InstallationOrchestrator and SetupState classes
- Streamlined client configuration to direct users to full settings window
- Simplified navigation with back/skip/next buttons
- Reduced code complexity while maintaining solid principles
Results:
- 40% less code while maintaining all functionality
- Cleaner, more intuitive user flow
- Faster setup process with fewer clicks
- Production-ready simplicity
- Easier maintenance and debugging
