This reverts commit 8c6eaaad07545cef047769f2c52fe506545a8161.
The includeStacktrace parameter was working backwards - when false,
it would return the full message with embedded stack traces, and when
true, it would extract the stack trace but the logic was inverted.
Changes:
- Always extract the first line as the message text
- Only populate stackTrace field when includeStacktrace is true
- Ensures clean, summary-only messages when includeStacktrace is false
- Properly separates stack traces into their own field when requested
This matches the expected Unity console behavior where the summary
is shown by default, and stack traces are only shown when expanded.
* 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

* 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
