* Add TDD tests for MCP material management issues
- MCPMaterialTests.cs: Tests for material creation, assignment, and data reading
- MCPParameterHandlingTests.cs: Tests for JSON parameter parsing issues
- SphereMaterialWorkflowTests.cs: Tests for complete sphere material workflow
These tests document the current issues with:
- JSON parameter parsing in manage_asset and manage_gameobject tools
- Material creation with properties
- Material assignment to GameObjects
- Material component data reading
All tests currently fail (Red phase of TDD) and serve as specifications
for what needs to be fixed in the MCP system.
* Refine TDD tests to focus on actual MCP tool parameter parsing issues
- Removed redundant tests that verify working functionality (GameObjectSerializer, Unity APIs)
- Kept focused tests that document the real issue: MCP tool parameter validation
- Tests now clearly identify the root cause: JSON string parsing in MCP tools
- Tests specify exactly what needs to be fixed: parameter type flexibility
The issue is NOT in Unity APIs or serialization (which work fine),
but in MCP tool parameter validation being too strict.
* Fix port discovery protocol mismatch
- Update _try_probe_unity_mcp to recognize Unity bridge welcome message
- Unity bridge sends 'WELCOME UNITY-MCP' instead of JSON pong response
- Maintains backward compatibility with JSON pong format
- Fixes MCP server connection to Unity Editor
* Resolve merge: unify manage_gameobject param coercion and schema widening
* Tests: add MaterialParameterToolTests; merge port probe fix; widen tool schemas for JSON-string params
* feat(material): support direct shader property keys and texture paths; add EditMode tests
* chore(tests): track required .meta files; remove ephemeral Assets/Editor test helper
* fix(manage_gameobject): validate parsed component_properties is a dict; return clear error

* Resolve merge: unify manage_gameobject param coercion and schema widening
* Tests: add MaterialParameterToolTests; merge port probe fix; widen tool schemas for JSON-string params
* refactor: extract JSON coercion helper; docs + exception narrowing\nfix: fail fast on bad component_properties JSON\ntest: unify setup, avoid test-to-test calls\nchore: use relative MCP package path
* chore(tests): track MCPToolParameterTests.cs.meta to keep GUID stable
* test: decouple MaterialParameterToolTests with helpers (no inter-test calls)
* deps: add tomli>=2.3.0 dependency to UnityMcpServer package
* 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
* Run get tests as a coroutine because it doesn't return results immediately
This works but it spams logs like crazy, maybe there's a better/simpler way
* refactor: migrate from coroutines to async/await for test retrieval and command execution
* 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
* Set max_retries to 5
This connection module needs a lookover. The retries should be an exponential backoff and we could structure why it's failing so much
* Use pydantic model to structure the error output
* fix: initialize data field in GetTestsResponse to avoid potential errors
* Don't return path parameter
* feat: add Unity test runner execution with structured results and Python bindings
* refactor: simplify GetTests by removing mode filtering and related parsing logic
* refactor: move test runner functionality into dedicated service interface
* feat: add resource retrieval telemetry tracking with new record type and helper function
* fix: convert tool functions to async and await ctx.info calls
* refactor: reorganize menu item functionality into separate execute and get commands
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.
* fix: replace tomllib with tomli for Python 3.10 compatibility in telemetry module
* Remove confusing comment
* refactor: improve error handling and simplify test retrieval logic in GetTests commands
* No cache by default
* docs: remove redundant comment for HandleCommand method in ExecuteMenuItem
* First pass at new UI
* Point to new UI
* 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
* fix: update Claude Code MCP server registration to use lowercase unityMCP name and correct the manual installation instructions
* fix: add Claude CLI directory to PATH for node/nvm environments
* Clarify how users will see MCP tools
* Add a keyboard shortcut to open the window
* feat: add server download UI and improve installation status messaging
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 download location
* style: improve dropdown and settings layout responsiveness with flex-shrink and max-width
* feat: add package.json version detection and refactor path utilities
* refactor: simplify imports and use fully qualified names in ServerInstaller.cs
* refactor: replace Unity Debug.Log calls with custom McpLog class
* 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
* fix: add file existence check before opening configuration file
* refactor: simplify asset path handling and remove redundant helper namespace references
* docs: update code block syntax highlighting in UI changes doc
* docs: add code block syntax highlighting for file structure example
* feat: import UnityEditor.UIElements namespace for UI components for Unity 2021 compatibility
* refactor: rename Python server references to MCP server for consistency
* fix: reset client status label color after error state is cleared
* Replace the phrase "Python server" with "MCP server"
* MInor doc clarification
* docs: add path override methods for UV and Claude CLI executables
* 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
* chore: update unity-mcp package path to MCPForUnity directory
* 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.
