* feat: Add project-scoped tools flag to control custom tool registration behavior
Add `--project-scoped-tools` CLI flag and `UNITY_MCP_PROJECT_SCOPED_TOOLS` environment variable to control whether custom tools are registered globally or scoped to specific Unity projects.
Closes#416
* Add .meta file
* feat: Add project-scoped tools toggle for local HTTP transport
Add UI toggle in Connection section to control project-scoped tools flag when using HTTP Local transport. The toggle:
- Defaults to enabled (true)
- Persists state in EditorPrefs
- Only displays when HTTP Local transport is selected
- Automatically appends `--project-scoped-tools` flag to uvx server command
- Updates manual config display when toggled

* fix: reduce per-frame GC allocations causing editor hitches (issue #577)
Eliminate memory allocations that occurred every frame, which triggered
garbage collection spikes (~28ms) approximately every second.
Changes:
- EditorStateCache: Skip BuildSnapshot() entirely when state unchanged
(check BEFORE building). Increased poll interval from 0.25s to 1.0s.
Cache DeepClone() results to avoid allocations on GetSnapshot().
- TransportCommandDispatcher: Early exit before lock/list allocation
when Pending.Count == 0, eliminating per-frame allocations when idle.
- StdioBridgeHost: Same early exit pattern for commandQueue.
- MCPForUnityEditorWindow: Throttle OnEditorUpdate to 2-second intervals
instead of every frame, preventing expensive socket checks 60+/sec.
Fixes GitHub issue #577: High performance impact even when MCP server is off
* fix: prevent multiple domain reloads when calling refresh_unity (issue #577)
Root Cause:
- send_command() had a hardcoded retry loop (min 6 attempts) on connection errors
- Each retry resent the refresh_unity command, causing Unity to reload 6 times
- retry_on_reload=False only controlled reload-state retries, not connection retries
The Fix:
1. Unity C# (MCPForUnity/Editor):
- Added --reinstall flag to uvx commands in dev mode
- Ensures local development changes are picked up by uvx/Claude Code
- Applies to all client configurators (Claude Code, Codex, etc.)
2. Python Server (Server/src):
- Added max_attempts parameter to send_command()
- Pass max_attempts=0 when retry_on_reload=False
- Fixed type handling in refresh_unity.py (handle MCPResponse objects)
- Added timeout to connection error recovery conditions
- Recovery logic now returns success instead of error to prevent client retries
Changes:
- MCPForUnity/Editor: Added --reinstall to dev mode uvx commands
- Server/refresh_unity.py: Fixed type handling, improved error recovery
- Server/unity_connection.py: Added max_attempts param, disable retries when retry_on_reload=False
Result: refresh_unity with compile=request now triggers only 1 domain reload instead of 6

* fix: UI and server stability improvements
Unity Editor (C#):
- Fix "Resuming..." stuck state when manually clicking End Session
Clear ResumeStdioAfterReload and ResumeHttpAfterReload flags in
OnConnectionToggleClicked and EndOrphanedSessionAsync to prevent
UI from getting stuck showing "Resuming..." with disabled button
- Remove unsupported --reinstall flag from all uvx command builders
uvx does not support --reinstall and shows warning when used
Use --no-cache --refresh instead for dev mode cache busting
Python Server:
- Add "aborted" to connection error patterns in refresh_unity
Handle WinError 10053 (connection aborted) gracefully during
Unity domain reload, treating it as expected behavior
- Add WindowsSafeRotatingFileHandler to suppress log rotation errors
Windows file locking prevents log rotation when file is open by
another process; catch PermissionError to avoid noisy stack traces
- Fix packaging: add py-modules = ["main"] to pyproject.toml
setuptools.packages.find only discovers packages (directories with
__init__.py), must explicitly list standalone module files
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
* docs: improve refresh_unity connection loss handling documentation
Add detailed comments and logging to clarify why connection loss during
compile is treated as success (expected domain reload behavior, not failure).
This addresses PR feedback about potentially masking real connection errors.
The logic is intentional and correct:
- Connection loss only treated as success when compile='request'
- Domain reload causing disconnect is expected Unity behavior
- Subsequent wait_for_ready loop validates Unity becomes ready
- Prevents multiple domain reload loops (issue #577)
Added logging for observability:
- Info log when expected disconnect detected
- Warning log for non-recoverable errors

* fix: add missing logger import in refresh_unity
Missing logger import causes NameError at runtime when connection
loss handling paths are triggered (lines 82 and 91).

* fix: address code review feedback on thread safety and semantics
Addresses four issues raised in code review:
1. EditorStateCache.GetSnapshot() - Remove shared cached clone
- Revert to always returning fresh DeepClone() to prevent mutation bugs
- Main GC optimization remains: state-change detection prevents
unnecessary _cached rebuilds (the expensive operation)
- Removed _cachedClone and _cachedCloneSequence fields
2. refresh_unity.py - Fix blocking reason terminology mismatch
- Changed "asset_refresh" to "asset_import" to match activityPhase
values from EditorStateCache.cs
- Ensures asset import is correctly detected as blocking state
3. TransportCommandDispatcher - Fix unsynchronized Count access
- Moved Pending.Count check inside PendingLock
- Prevents data races and InvalidOperationException from concurrent
dictionary access
4. StdioBridgeHost - Fix unsynchronized Count access
- Moved commandQueue.Count check inside lockObj
- Ensures all collection access is properly serialized
All changes maintain the GC allocation optimizations while fixing
thread safety violations and semantic contract changes.

* fix: address code review feedback on thread safety and timeout handling
- refresh_unity.py: Track readiness explicitly and return failure on timeout
instead of silently returning success when wait loop exits without confirming
ready_for_tools=true
- McpClientConfiguratorBase.cs: Add thread safety guard for Configure() call
in CheckStatusWithProjectDir(). Changed default attemptAutoRewrite to false
and added runtime check to prevent calling Configure() from background threads.

* fix: search inactive objects when setActive=true in modify
When trying to activate an inactive GameObject via manage_gameobject modify with setActive=true, the lookup would fail because inactive objects were not included in the search by default.
Now automatically sets searchInactive=true when setActive=true is specified, allowing inactive objects to be found and activated.
* fix: Add special handling for UIDocument serialization to prevent infinite loops (#585)
UIDocument.rootVisualElement contains circular parent/child references that
can cause infinite serialization loops. This adds special handling similar to
Transform and Camera components.
The fix:
- Safely serializes panelSettings, visualTreeAsset, sortingOrder, enabled, parentUI
- Explicitly skips rootVisualElement to prevent circular reference issues
- Includes a note explaining why rootVisualElement is skipped
Tested on Unity 2021.3 and Unity 6.3.
* refactor: Extract SerializeAssetReference helper and align UIDocument structure
- Add SerializeAssetReference() helper for consistent asset reference serialization
- UIDocument now uses same return structure as Camera (typeName, instanceID, properties)
- Reduces code duplication in special-case handlers
- Enhanced test coverage to verify structure matches Camera pattern
* fix: Handle UIDocument subclasses and add negative assertion for rootVisualElement
Address code review feedback:
- Add IsOrDerivedFrom() helper to detect UIDocument and any subclasses by walking
the base-type chain, ensuring derived types also get special-case handling
- Add negative assertion verifying rootVisualElement is NOT in serialized output
* docs: Streamline README for faster onboarding
Major restructuring to reduce README from ~500 lines to ~200 lines while preserving all essential information.
Changes:
- Add prominent "Quick Start" section at top with prerequisites and 5-step setup
- Highlight Git package URL with GitHub TIP admonition for visibility
- Collapse detailed content into expandable sections:
- Features & Tools
- Manual Configuration (with nested stdio legacy config)
- Multiple Unity Instances
- Roslyn Script Validation
- Troubleshooting
- Contributing
- Telemetry & Privacy
- Keep Star History and Coplay sections always visible
- Condense tools/resources from verbose lists to compact bullet format
- Add step 5 for client connection (toggle for Cursor/Windsurf/Antigravity)
The goal is 1-2 screens of visible content for new users to get started quickly,
with all details accessible via dropdowns for those who need them.
* docs: Address review feedback
- Add `text` language identifier to Git URL code blocks for linter compliance
- Clarify step 5 client connection instructions with clearer categorization
- Add nested dropdown for manual Roslyn DLL installation option
* docs: Indent nested Roslyn manual installation dropdown
* docs: Add wiki links to Troubleshooting section
EditorApplication.isCompiling can return true in Play mode even when Unity
is not actually compiling, causing MCP tools to incorrectly return
"busy/compiling" errors.
This adds a GetActualIsCompiling() helper that double-checks with
CompilationPipeline.isCompiling via reflection when in Play mode to filter
out these false positives.
Fixes#549
When trying to activate an inactive GameObject via manage_gameobject modify with setActive=true, the lookup would fail because inactive objects were not included in the search by default.

* fix: resolve UV path override not being detected in System Requirements
Fixes#538
The System Requirements panel showed "UV Package Manager: Not Found" even
when a valid UV path override was configured in Advanced Settings.
Root cause: PlatformDetectorBase.DetectUv() only searched PATH with bare
command names ("uvx", "uv") and never consulted PathResolverService which
respects the user's override setting.
Changes:
- Refactor DetectUv() to use PathResolverService.GetUvxPath() which checks
override path first, then system PATH, then falls back to "uvx"
- Add TryValidateUvExecutable() to verify executables by running --version
instead of just checking File.Exists
- Prioritize PATH environment variable in EnumerateUvxCandidates() for
better compatibility with official uv install scripts
- Fix process output read order (ReadToEnd before WaitForExit) to prevent
potential deadlocks
Co-Authored-By: ChatGLM 4.7 <noreply@zhipuai.com>
* fix: improve uv/uvx detection robustness on macOS and Linux
- Read both stdout and stderr when validating uv/uvx executables
- Respect WaitForExit timeout return value instead of ignoring it
- Fix version parsing to handle extra tokens like "(Homebrew 2025-01-01)"
- Resolve bare commands ("uv"/"uvx") to absolute paths after validation
- Rename FindExecutableInPath to FindUvxExecutableInPath for clarity

* refactor: unify process execution with ExecPath.TryRun and add Windows PATH augmentation
Replace direct Process.Start calls with ExecPath.TryRun across all platform detectors.

- Adds proper timeout handling with process termination
- Removes redundant fallback logic and simplifies version parsing
- Adds Windows PATH augmentation with common uv, npm, and Python installation paths

* fix: improve version parsing to handle both spaces and parentheses
The version extraction logic now properly handles outputs like:
- "uvx 0.9.18" -> "0.9.18"
- "uvx 0.9.18 (hash date)" -> "0.9.18"
- "uvx 0.9.18 extra info" -> "0.9.18"
Uses Math.Min to find the first occurrence of either space or parenthesis.

* refactor: improve platform detectors with absolute path resolution
- Add absolute path resolution in TryValidatePython and TryValidateUvWithPath for better UI display
- Fix BuildAugmentedPath to avoid PATH duplication
- Add comprehensive comments for version parsing logic
- Ensure cross-platform consistency across all three detectors
- Fix override path validation logic with clear state handling
- Fix platform detector path resolution and Python version detection
- Use UserProfile consistently in GetClaudeCliPath instead of Personal
- All platforms now use protected BuildAugmentedPath method
This change improves user experience by displaying full paths in the UI
while maintaining robust fallback behavior if path resolution fails.

Also adjust Claude NL suite licensing checks so it can run in the top-level repo.
The allowNudge parameter was attempting to fix Unity 6 compilation loops
by skipping QueuePlayerLoopUpdate, but this was not the root cause.
The actual issue (fixed by #559's Unity 6+ preprocessor guard) is that
EditorApplication.update callbacks don't survive domain reloads properly
in Unity 6+.
Since #559 skips WaitForUnityReadyAsync entirely on Unity 6+ when compile
is requested, the allowNudge guard is redundant and can be removed.
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
* fix: Prevent infinite compilation loop in Unity 6 when using wait_for_ready
Skip WaitForUnityReadyAsync when compileRequested is true. The
EditorApplication.update polling doesn't survive domain reloads
properly in Unity 6, causing infinite compilation loops.
When compilation is requested, return immediately and let the
client poll editor_state resource instead.
Fixes#557
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
* fix: Use actuallyWaited for hint message consistency

* refactor: Gate Unity 6 fix with version check and rename variable
Address code review feedback:
- Use UNITY_6000_0_OR_NEWER preprocessor directive to only apply the

- Rename actuallyWaited to shouldWaitForReady for clarity, as it
represents the decision to wait rather than a post-hoc result

* Fix test job state management after domain reload
- TestRunnerService.RunFinished: Always clean up job state even when
_runCompletionSource is null (happens after PlayMode domain reload)
- TestJobManager: Detect and clear stale jobs (5+ min without updates)
on startup to recover from stuck state after domain reload
- refresh_unity.py: Add "could not connect" to retryable errors when
wait_for_ready=True, so connection failures during domain reload
trigger waiting instead of immediate failure

* Add focus nudge to handle OS-level throttling during PlayMode tests
When Unity is unfocused, macOS App Nap (and similar OS features) can
throttle the process, causing PlayMode tests to stall even with Unity
No Throttling mode enabled.
Changes:
- Add ApplyNoThrottlingPreemptive() to TestRunnerNoThrottle for early
throttle prevention before PlayMode Execute()
- Add focus_nudge.py utility that temporarily focuses Unity and returns
focus to the original app (supports macOS, Windows, Linux)
- Integrate focus nudge into get_test_job polling - when tests appear
stalled (unfocused + no progress for 10s), automatically nudge Unity

The old CLI file map does not seem to work for the latest CC(V2.1.4), with errors that cannot recognize any symbols after uvx.exe, whether it be --no-cache, --refresh, or --from. I did not find any documentation change of why this cannot use.
I temporarily revert the current Claude Code registration to the old JSON way, which still works. Will look for a fix that could retain the CLI command usage.
* feat: add test coverage tracking with pytest-cov
- Add pytest-cov>=4.1.0 to dev dependencies
- Configure coverage in pyproject.toml (run, report, html)
- Integrate coverage reports into CI workflow
- Update .gitignore for coverage artifacts
- Document coverage usage in docs/README-DEV.md
Current coverage baseline: 34.45%
* fix: correct TOML escaping and remove redundant
* docs: add Chinese translation for code coverage section
* fix: regenerate uv.lock to resolve merge conflict
* Update the major tag of a version as well when publishing to Docker
Useful for the asset store releases
* feat: trigger publish workflows automatically after version bump and release creation
It should work in theory, and correctly release to Docker and pypi via tags.
* feat: consolidate release workflows into single pipeline with reusable actions
Refactored version bump, Docker publish, and PyPI publish workflows into a unified release pipeline that runs sequentially. Created reusable composite actions for Docker and PyPI publishing to eliminate duplication.
Changes:
- Rename bump-version.yml to release.yml with three jobs: bump, publish_docker, publish_pypi
- Create .github/actions/publish-docker/action.yml with configurable inputs for image, version, branch
- UnityTypeConverters.cs referenced McpLog (Editor-only) from Runtime asmdef
- This caused CS0103 build errors in player builds
- Replaced with UnityEngine.Debug.LogWarning for runtime compatibility
Also cleaned up test file:
- Removed stale NL test artifacts (Build marker, Tail test comments)
- Removed unused local functions causing CS8321 warnings
* fix: use PyPI as default server source instead of git URL
Fixes Windows installation failures caused by long path issues when
cloning the full repository (MAX_PATH 260 char limit exceeded).
- Change default from git+https://github.com/CoplayDev/unity-mcp to
mcpforunityserver=={version} PyPI package
- Rename GetMcpServerGitUrl() to GetMcpServerPackageSource()
- Keep deprecated wrapper for backwards compatibility
- Update UI help text to show local dev override example only
- Update tests to expect PyPI package reference
* fix: use forward slashes in deployment path display
Fixes UI rendering issue where backslashes in Windows paths were
interpreted as escape sequences (e.g. \U, \u showing as boxes).
Convert backslashes to forward slashes for display in:
- Target path label
- Backup path label
- Add DetermineCallSucceeded() to check command success via IMcpResponse interface or JObject/JToken 'success' field
- Track invocationFailureCount and set anyCommandFailed flag when commands fail
- Implement fail-fast behavior to stop batch execution on first failure when failFast=true
- Update commandResults to use computed callSucceeded value instead of hardcoded true
feat(game_object_create): enhance asset
* refactor: Split ParseColorOrDefault into two overloads and change default to Color.white
* Auto-format Python code
* Remove unused Python module
* Refactored VFX functionality into multiple files
Tested everything, works like a charm
* Rename ManageVfx folder to just Vfx
We know what it's managing
* Clean up whitespace on plugin tools and resources
* Make ManageGameObject less of a monolith by splitting it out into different files
* Remove obsolete FindObjectByInstruction method
We also update the namespace for ManageVFX
* Add local test harness for fast developer iteration
Scripts for running the NL/T/GO test suites locally against a GUI Unity
Editor, complementing the CI workflows in .github/workflows/.
Benefits:
- 10-100x faster than CI (no Docker startup)
- Real-time Unity console debugging
- Single test execution for rapid iteration
- Auto-detects HTTP vs stdio transport
Usage:
./scripts/local-test/setup.sh # One-time setup
./scripts/local-test/quick-test.sh NL-0 # Run single test
./scripts/local-test/run-nl-suite-local.sh # Full suite
See scripts/local-test/README.md for details.
Also updated .gitignore to:
- Allow scripts/local-test/ to be tracked
- Ignore generated artifacts (reports/*.xml, .claude/local/, .unity-mcp/)
* Fix issue #525: Save dirty scenes for all test modes
Move SaveDirtyScenesIfNeeded() call outside the PlayMode conditional
so EditMode tests don't get blocked by Unity's "Save Scene" modal dialog.
This prevents MCP from timing out when running EditMode tests with unsaved
scene changes.
* refactor: Consolidate editor state resources into single canonical implementation
Merged EditorStateV2 into EditorState, making get_editor_state the canonical resource. Updated Unity C# to use EditorStateCache directly. Enhanced Python implementation with advice/staleness enrichment, external changes detection, and instance ID inference. Removed duplicate EditorStateV2 resource and legacy fallback mapping.
* Validate editor state with Pydantic models in both C# and Python
Added strongly-typed Pydantic models for EditorStateV2 schema in Python and corresponding C# classes with JsonProperty attributes. Updated C# to serialize using typed classes instead of anonymous objects. Python now validates the editor state payload before returning it, catching schema mismatches early.
* Consolidate run_tests and run_tests_async into single async implementation
Merged run_tests_async into run_tests, making async job-based execution the default behavior. Removed synchronous blocking test execution. Updated RunTests.cs to start test jobs immediately and return job_id for polling. Changed TestJobManager methods to internal visibility. Updated README to reflect single run_tests_async tool. Python implementation now uses async job pattern exclusively.
* Validate test job responses with Pydantic models in Python
* Change resources URI from unity:// to mcpforunity://
It should reduce conflicts with other Unity MCPs that users try, and to comply with Unity's requests regarding use of their company and product name
* Update README with all tools + better listing for resources
* Update other references to resources
* Updated translated doc - unfortunately I cannot verify
* Update the Chinese translation of the dev docks
* Change menu item from Setup Window to Local Setup Window
We now differentiate whether it's HTTP local or remote
* Fix URIs for menu items and tests
* Shouldn't have removed it
* fix: add missing FAST_FAIL_TIMEOUT constant in PluginHub
The FAST_FAIL_TIMEOUT class attribute was referenced on line 149 but never
defined, causing AttributeError on every ping attempt. This error was silently
caught by the broad 'except Exception' handler, causing all fast-fail commands
(read_console, get_editor_state, ping) to fail after 6 seconds of retries with
'ping not answered' error.
Added FAST_FAIL_TIMEOUT = 10 to define a 10-second timeout for fast-fail
commands, matching the intent of the existing fast-fail infrastructure.
* feat(ScriptableObject): enhance dry-run validation for AnimationCurve and Quaternion
Dry-run validation now validates value formats, not just property existence:
- AnimationCurve: Validates structure ({keys:[...]} or direct array), checks
each keyframe is an object, validates numeric fields (time, value, inSlope,
outSlope, inWeight, outWeight) and integer fields (weightedMode)
- Quaternion: Validates array length (3 for Euler, 4 for raw) or object
structure ({x,y,z,w} or {euler:[x,y,z]}), ensures all components are numeric
Refactored shared validation helpers into appropriate locations:
- ParamCoercion: IsNumericToken, ValidateNumericField, ValidateIntegerField
- VectorParsing: ValidateAnimationCurveFormat, ValidateQuaternionFormat
Added comprehensive XML documentation clarifying keyframe field defaults
(all default to 0 except as noted).
Added 5 new dry-run validation tests covering valid and invalid formats
for both AnimationCurve and Quaternion properties.
* test: fix integration tests after merge
- test_refresh_unity_retry_recovery: Mock now handles both refresh_unity and
get_editor_state commands (refresh_unity internally calls get_editor_state
when wait_for_ready=True)
- test_run_tests_async_forwards_params: Mock response now includes required
'mode' field for RunTestsStartResponse Pydantic validation
- test_get_test_job_forwards_job_id: Updated to handle GetTestJobResponse as
Pydantic model instead of dict (use model_dump() for assertions)
* Update warning message to apply to all test modes
Follow-up to PR #527: Since SaveDirtyScenesIfNeeded() now runs for all test modes, update the warning message to say 'tests' instead of 'PlayMode tests'.
* feat(run_tests): add wait_timeout to get_test_job to avoid client loop detection
When polling for test completion, MCP clients like Cursor can detect the
repeated get_test_job calls as 'looping' and terminate the agent.
Added wait_timeout parameter that makes the server wait internally for tests
to complete (polling Unity every 2s) before returning. This dramatically
reduces client-side tool calls from 10-20 down to 1-2, avoiding loop detection.
Usage: get_test_job(job_id='xxx', wait_timeout=30)
- Returns immediately if tests complete within timeout
- Returns current status if timeout expires (client can call again)
- Recommended: 30-60 seconds
* fix: use Pydantic attribute access in test_run_tests_async for merge compatibility
* revert: remove local test harness - will be submitted in separate PR
* fix: stdio transport survives test runs without UI flicker
Root cause: WriteToConfigTests.TearDown() was unconditionally deleting
UseHttpTransport EditorPref even when tests were skipped on Windows
(NUnit runs TearDown even after Assert.Ignore).
Changes:
- Fix WriteToConfigTests to save/restore prefs instead of deleting
- Add centralized ShouldForceUvxRefresh() for local dev path detection
- Clean stale Python build/ artifacts before client configuration
- Improve reload handler flag management to prevent stuck Resuming state
- Show Resuming status during stdio bridge restart
- Initialize client config display on window open
