* chore: update Unity version from 2021.3.45f1 to 2021.3.45f2
Older Unity version had the security vulnerability, so we update it
* feat: add dynamic version display in editor window settings
* refactor: remove manual license file handling from Unity test workflow
* Revert "refactor: remove manual license file handling from Unity test workflow"
This reverts commit a6ab3d982e792039c01a4afd353e61c7e22a2c3c.
* feat: add Unity license credentials to Docker containers in CI workflow
* refactor: replace manual Unity license activation with game-ci/unity-activator
* refactor: simplify Unity CI setup by removing game-ci activation and using built-in license handling
* fix: improve Unity license activation in CI by using unityci image's built-in activation flow
* refactor: activate once in a temporary container, then reuse the license in the long-running container
Now we got the license secret to be read, we got this error: "Machine bindings don't match". So it seems that the license I generated locally can't be used.
So we need to activate the license within the container
* Revert "refactor: activate once in a temporary container, then reuse the license in the long-running container"
This reverts commit f6a9aa68f910df37cede6f83d535098be2a9f80b.

* feat: dynamically fetch package version from pyproject.toml for telemetry
* Add pydantic
* feat: add resource registry for MCP resource auto-discovery
* feat: add telemetry decorator for tracking MCP resource usage
* feat: add auto-discovery and registration system for MCP resources
* feat: add resource registration to MCP server initialization
* feat: add MCPResponse model class for standardized API responses
* refactor: replace Debug.Log calls with McpLog wrapper for consistent logging
* feat: add test discovery endpoints for Unity Test Framework integration
We haven't connected them as yet, still thinking about how to do this neatly
* Fix server setup
* refactor: reduce log verbosity by changing individual resource/tool registration logs to debug level
* chore: bump mcp[cli] dependency from 1.15.0 to 1.17.0
* refactor: remove Context parameter and add uri keyword argument in resource decorator
The Context parameter doesn't work on our version of FastMCP
* chore: upgrade Python base image to 3.13 and simplify Dockerfile setup
* fix: apply telemetry decorator before mcp.tool to ensure proper wrapping order
* fix: swap order of telemetry and resource decorators to properly wrap handlers
* fix: update log prefixes for consistency in logging methods
* Fix compile errors
* feat: extend command registry to support both tools and resources

* feat: add optional error field to MCPResponse model
* Increased timeout because loading tests can take some time
* Make message optional so error responses that only have success and error don't cause Pydantic errors

An MCP resource for retrieval, and a simple command to execute. Because it's a resource, it's easier for the user to see what's in the menu items
* refactor: rename manage_menu_item to execute_menu_item and update tool examples to use async/await
We'll eventually put a section for resources
* Revert "fix: convert tool functions to async and await ctx.info calls"
This reverts commit 012ea6b7439bd1f2593864d98d03d9d95d7bdd03.

* Refactor: New Service-Based MCP Editor Window Architecture
We separate the business logic from the UI rendering of the new editor window with new services.
I didn't go full Dependency Injection, not sure if I want to add those deps to the install as yet, but service location is fairly straightforward.
Some differences with the old window:
- No more Auto-Setup, users will manually decide what they want to do
- Removed Python detection warning, we have a setup wizard now
- Added explicit path overrides for `uv` and the MCP server itself
* style: add flex-shrink and overflow handling to improve UI element scaling
* fix: update UI configuration and visibility when client status changes
* feat: add menu item to open legacy MCP configuration window
* refactor: improve editor window lifecycle handling with proper update subscription
* feat: add auto-verification of bridge health when connected

This is needed for the Unity Asset Store, which doesn't have the Python server embedded.
* feat: add dynamic asset path detection to support both Package Manager and Asset Store installations
* fix: replace unicode emojis with escaped characters in status messages
* feat: add server package creation and GitHub release publishing to version bump workflow
* fix: add v prefix to server package filename in release workflow

* fix: extract server files to temp directory before moving to final location
* docs: add v6 UI documentation and screenshots with service architecture overview
* docs: add new UI Toolkit-based editor window with service architecture and path overrides
* feat: improve package path resolution to support Package Manager and Asset Store installations
* Change Claude Code's casing back to "UnityMCP"
There's no need to break anything as yet
* fix: update success dialog text to clarify manual bridge start requirement
* refactor: move RefreshDebounce and ManageScriptRefreshHelpers classes inside namespace
* feat: add Asset Store fallback path detection for package root lookup
* fix: update server installation success message to be more descriptive
* refactor: replace Unity Debug.Log calls with custom McpLog utility

* docs: update service locator registration method name from SetCustomImplementation to Register
* Copy UnityMcpBridge into a new MCPForUnity folder
This is to close#284
* refactor: rename UnityMcpBridge directory to MCPForUnity in docs
* chore: rename UnityMcpBridge directory to MCPForUnity across workflow files
* chore: rename UnityMcpBridge directory to MCPForUnity across all files
* refactor: update import paths from UnityMcpBridge to MCPForUnity across test files
* fix: update module import paths to use MCPForUnity instead of UnityMcpBridge

* feat: add OneTimeSetUp to initialize CommandRegistry before tests run
Hopefully fix the CI failures
* Apply recent fix to new folder
* Temporarily trigger tests to see if CI works
* Revert "Temporarily trigger tests to see if CI works"
It works!
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

* 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
