* feat: migrate to FastMCP 2.0 (v2.12.5)
- Update pyproject.toml to use fastmcp>=2.12.5 instead of mcp[cli]
- Replace all imports from mcp.server.fastmcp to fastmcp
- Maintain MCP protocol compliance with mcp>=1.16.0
- All 15 files updated with new import statements
- Server and tools registration working with FastMCP 2.0
* chore: bump MCP for Unity to 6.2.2 and widen numeric tool params (asset search/read_resource/run_tests) for better LLM compatibility
* chore: bump installed server_version.txt to 6.2.2 so Unity installer logs correct version
* fix(parameters): apply parameter hardening to read_console, manage_editor, and manage_gameobject
- read_console: accept int|str for count parameter with coercion
- manage_editor: accept bool|str for wait_for_completion with coercion
- manage_gameobject: accept bool|str for all boolean parameters with coercion
- All tools now handle string parameters gracefully and convert to proper types internally
* chore(deps): drop fastmcp, use mcp>=1.18.0; update imports to mcp.server.fastmcp
* chore(deps): re-add fastmcp>=2.12.5, relax mcp to >=1.16.0
Adds fastmcp as explicit dependency for FastMCP 2.0 migration.
Relaxes mcp version constraint to support broader compatibility.

* test: remove obsolete mcp stubs for FastMCP 2.0 compatibility
Removes stub mcp modules from test files that were conflicting with
the real mcp and fastmcp packages now installed as dependencies.
Adds tests/__init__.py to make tests a proper Python package.
This fixes test collection errors after migrating to FastMCP 2.0.
Test results: 40 passed, 7 xpassed, 5 skipped, 1 failed (pre-existing)

* feat: add entry point script and additional Python modules to server package
Now we can run this server with `uvx`
* refactor: improve package version detection to support both installed and development environments
* refactor: simplify release workflow by removing server packaging step
* Update github-repo-stats.yml
* pytest: make harness MCPForUnity-only; remove UnityMcpBridge paths from tests; route tools.manage_script via unity_connection for reliable monkeypatching; fix ctx usage; all tests green (39 pass, 5 skip, 7 xpass)
* Add missing meta for MaterialMeshInstantiationTests.cs (Assets)
* bridge/tools/manage_script: fix missing unity_connection prefix in validate_script; tests: tidy manage_script_uri unused symbols and arg names
* tests: rename to script_apply_edits_module; extract DummyContext to tests/test_helpers and import; add telemetry stubs in tests to avoid pyproject I/O
* tests: import cleanup and helper extraction; telemetry: prefer plain config and opt-in env override; test stubs and CWD fixes; exclude Bridge from pytest discovery
* chore: remove unintended .wt-origin-main gitlink and ignore folder
* tests: nit fixes (unused-arg stubs, import order, path-normalized ignore hook); telemetry: validate config endpoint; read_console: action optional
* Add development dependencies to pyproject.toml
- Add [project.optional-dependencies] section with dev group
- Include pytest>=8.0.0 and pytest-anyio>=0.6.0
- Add Development Setup section to README-DEV.md with installation and testing instructions
* Revert "Update github-repo-stats.yml"
This reverts commit 8ae595d2f4f2525b0e44ece948883ea37138add4.
* test: improve test clarity and modernize asyncio usage
- Add explanation for 200ms timeout in backpressure test
- Replace manual event loop creation with asyncio.run()
- Add assertion message with actual elapsed time for easier debugging
* refactor: remove duplicate DummyContext definitions across test files
Replace 7 duplicate DummyContext class definitions with imports from tests.test_helpers.
This follows DRY principles and ensures consistency across the test suite.
* chore: remove unused _load function from test_edit_strict_and_warnings.py
Dead code cleanup - function was no longer used after refactoring to dynamic tool registration.
* docs: add comment explaining CWD manipulation in telemetry test
Clarify why os.chdir() is necessary: telemetry.py calls get_package_version()
at module load time, which reads pyproject.toml using a relative path.
Acknowledges the fragility while explaining why it's currently required.
* Fix issue #308: Find py files in MCPForUnityTools and version.txt
This allows for auto finding new tools. A good dir on a custom tool would look like this:
CustomTool/
├── CustomTool.MCPEnabler.asmdef
├── CustomTool.MCPEnabler.asmdef.meta
├── ExternalAssetToolFunction.cs
├── ExternalAssetToolFunction.cs.meta
├── external_asset_tool_function.py
├── external_asset_tool_function.py.meta
├── version.txt
└── version.txt.meta
CS files are left in the tools folder. The asmdef is recommended to allow for dependency on MCPForUnity when MCP For Unity is installed:
asmdef example
{
"name": "CustomTool.MCPEnabler",
"rootNamespace": "MCPForUnity.Editor.Tools",
"references": [
"CustomTool",
"MCPForUnity.Editor"
],
"includePlatforms": [
"Editor"
],
"excludePlatforms": [],
"allowUnsafeCode": false,
"overrideReferences": false,
"precompiledReferences": [],
"autoReferenced": true,
"defineConstraints": [],
"versionDefines": [],
"noEngineReferences": false
}

* refactor: consolidate module discovery logic into shared utility function
* Remove unused imports
* feat: add Python tool registry and sync system for MCP server integration
* feat: add auto-sync processor for Python tools with Unity editor integration
* feat: add menu item to reimport all Python files in project
Good to give users a manual option
* Fix infinite loop error
Don't react to PythonToolAsset changes - it only needs to react to Python file changes.
And we also batch asset edits to minimise the DB refreshes
* refactor: move Python tool sync menu items under Window/MCP For Unity/Tool Sync
* Update docs
* Remove duplicate header
* feat: add OnValidate handler to sync Python tools when asset is modified
This fixes the issue with deletions in the asset, now file removals are synced

* 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

* 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
