- 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
- Add DevModeForceServerRefresh to EditorPrefs window known types

* Use ctx param
* Update Server/src/services/tools/run_tests.py

- Fix manage_script.py documentation (remove incorrect 'update' reference)
- Remove stale comments in execute_menu_item.py, manage_editor.py
- Remove misleading destructiveHint from manage_shader.py
C# Unity:
- Add Vector4Converter (commonly used, was missing)
- Fix Unity 2021 compatibility: replace FindObjectsByType with FindObjectsOfType
- Add path normalization in ObjectResolver before StartsWith check
- Improve ComponentOps.SetProperty conversion error detection
- Add Undo.RecordObject in ManageComponents before property modifications
- Improve error message clarity in ManageMaterial.cs

BlendXHash/BlendYHash now use 'reachX'/'reachY' to match the
actual animator parameter names.
* fix(windows): improve HTTP server detection and auto-start reliability
- Fix netstat detection on Windows by running netstat.exe directly instead
of piping through findstr (findstr returns exit code 1 when no matches,
causing false detection failures)
- Increase auto-start retry attempts (20→30) and delays (2s→3s) to handle
slow server starts during first install, version upgrades, and dev mode
- Only attempt blind connection after 20 failed detection attempts to reduce
connection error spam during server startup
- Remove verbose debug logs that were spamming the console every frame
* fix: auto-create tags and remove deprecated manage_gameobject actions
- ManageGameObject.cs: Check tag existence before setting; auto-create
undefined tags using InternalEditorUtility.AddTag() instead of relying
on exception handling (Unity logs warning, doesn't throw)
- manage_gameobject.py: Remove deprecated actions (find, get_components,
add_component, remove_component, set_component_property, get_component)
from Literal type - these are now handled by find_gameobjects and
manage_components tools
- Update test suite and unit tests to reflect new auto-create behavior
* fix: address code review feedback
Bug fixes:
- Fix searchInactive flag ignored in FindObjectsOfType (use includeInactive overload)
- Fix property lookup to try both original and normalized names for backwards compat
- Remove dead code for deprecated 'find' action validation
- Update error message to list only valid actions
Improvements:
- Add destructiveHint=True to manage_shader tool
- Limit fallback connection attempts (every 3rd attempt) to avoid spamming errors
- Consolidate PropertyConversion exception handlers to single catch block
- Add tag existence assertion and cleanup in tag auto-creation tests
Test fixes:
- Update SetComponentProperties_ContinuesAfterException log regex for new error format

* fix: Align test expectation with implementation error message case
* docs: update README tools and resources lists
- Add missing tools: manage_components, batch_execute, find_gameobjects, refresh_unity
- Add missing resources: gameobject_api, editor_state_v2
- Make descriptions more concise across all tools and resources
- Ensure documentation matches current MCP server functionality
* fix: Address code review feedback
- ParamCoercion: Use InvariantCulture for int/double parsing consistency
- ManageComponents: Remove redundant Undo.RecordObject (AddComponent handles undo)
- ManageScene: Replace deprecated FindObjectsOfType with FindObjectsByType
- GameObjectLookup: Add explanatory comment to empty catch block
- gameobject.py: Extract _validate_instance_id helper to reduce duplication
- Tests: Fix assertion for instanceID (Unity IDs can be negative)
* chore: Remove accidentally committed test artifacts
- Remove Materials folder (40 .mat files from interactive testing)
- Remove Shaders folder (5 noise shaders from testing)
- Remove test scripts (Bounce*, CylinderBounce* from testing)
- Remove Temp.meta and commit.sh
* test: Improve delete tests to verify actual deletion
- Delete_ByTag_DeletesMatchingObjects: Verify objects are actually destroyed
- Delete_ByLayer_DeletesMatchingObjects: Assert deletion using Unity null check
- Delete_MultipleObjectsSameName_DeletesCorrectly: Document first-match behavior
- Delete_Success_ReturnsDeletedCount: Verify count value if present
All tests now verify deletion occurred rather than just checking for a result.
* refactor: remove deprecated manage_gameobject actions
- Remove deprecated switch cases: find, get_components, get_component, add_component, remove_component, set_component_property
- Remove deprecated wrapper methods (423 lines deleted from ManageGameObject.cs)
- Delete ManageGameObjectFindTests.cs (tests deprecated 'find' action)
- Remove deprecated test methods from ManageGameObjectTests.cs
- Add GameObject resource URIs to README documentation
- Add batch_execute performance tips to README, tool description, and gameobject_api resource
- Enhance batch_execute description to emphasize 10-100x performance gains
Total: ~1200 lines removed. New API (find_gameobjects, manage_components, resources) is the recommended path forward.
* fix: Remove starlette stubs from conftest.py
Starlette is now a proper dependency via the mcp package, so we don't need
to stub it anymore. The real package handles all HTTP transport needs.
* fix: Multi-session UI improvements and HTTP instance recognition
- Separate server and session lifecycle in HTTP Local mode
- Show 'Start Server' / 'Stop Server' button for server control
- Show 'Start Session' / 'End Session' button when server is running
- No auto-join on server start (requires manual session start)
- Show instance name instead of port in session status (e.g. 'Session Active (ramble)')
- Use native project_hash for HTTP instance recognition instead of computed SHA256
- Fix test expectations for manage_asset JSON parsing error messages
* fix: Multi-session UI improvements and HTTP instance recognition
- Separate server and session lifecycle in HTTP Local mode
- Show 'Start Server' / 'Stop Server' button for server control
- Show 'Start Session' / 'End Session' button when server is running
- Auto-start session when THIS instance starts the server
- Require manual session start when connecting to external server
- Auto-detect and end orphaned sessions when server stops
- Show instance name instead of port in session status
- Use native project_hash for HTTP instance recognition
- Guard against empty hash with warning log
- Remove dead code (duplicate _safe_response)
- Add defensive path handling for instance name extraction
* Optimize read_console defaults and paging
* Fix read_console truncate test expectations
* Reduce read_console default count from 50 to 10
Further optimize token usage by reducing the default count from 50 to 10 entries. Even 10-20 messages with stack traces can be token-heavy. Added tests for default behavior and paging functionality. Updated tool description to document defaults and paging support.
* Fix ReadConsoleTests to include log type messages
The default types filter changed to ['error', 'warning'] (excluding 'log'), so tests using Debug.Log() need to explicitly request log messages. Also added format='detailed' to HandleCommand_Get_Works test since it accesses structured message fields.
* Address CodeRabbit review feedback
- Fix property naming consistency: next_cursor -> nextCursor (C# camelCase)
- Remove redundant EndGettingEntries call from catch block (already in finally)
- Extract stacktrace stripping to helper function (reduce duplication)
- Fix test mock to match actual C# response structure (items, nextCursor, truncated, total)
* perf: add early exit optimization for ReadConsole paging
- Add early exit in paging loop once page is filled, avoiding iteration
through remaining console entries (total becomes 'at least N')
- Prefix unused mock arguments with underscores in test_read_console_truncate.py
to suppress Ruff linter warnings
* refactor: give pageSize independent default, clarify count semantics
- Change pageSize resolution from 'pageSize ?? count ?? 50' to 'pageSize ?? 50'
so pageSize has its own default independent of count
- count now only serves as the non-paging limit
- Add XML docs to GetConsoleEntries with clear parameter descriptions
- Update Python tool annotations to document pageSize default (50) and
clarify that count is ignored when paging
* Add editor readiness v2, refresh tool, and preflight guards
* Detect external package changes and harden refresh retry
* feat: add TestRunnerNoThrottle and async test running with background stall prevention
- Add TestRunnerNoThrottle.cs: Sets editor to 'No Throttling' mode during test runs
with SessionState persistence across domain reload
- Add run_tests_async and get_test_job tools for non-blocking test execution
- Add TestJobManager for async test job tracking with progress monitoring
- Add ForceSynchronousImport to all AssetDatabase.Refresh() calls to prevent stalls
- Mark DomainReloadResilienceTests as [Explicit] with documentation explaining
the test infrastructure limitation (internal coroutine waits vs MCP socket polling)
- MCP workflow is unaffected - socket messages provide external stimulus that
keeps Unity responsive even when backgrounded
* refactor: simplify and clean up code
- Remove unused Newtonsoft.Json.Linq import from TestJobManager
- Add throttling to SessionState persistence (once per second) to reduce overhead
- Critical job state changes (start/finish) still persist immediately
- Fix duplicate XML summary tag in DomainReloadResilienceTests
* docs: add async test tools to README, document domain reload limitation
- Add run_tests_async and get_test_job to main README tools list
- Document background stall limitation for domain reload tests in DEV readme
* ci: add separate job for domain reload tests
Run [Explicit] domain_reload tests in their own job using -testCategory
* ci: run domain reload tests in same job as regular tests
Combines into single job with two test steps to reuse cached Library
* fix: address coderabbit review issues
- Fix TOCTOU race in TestJobManager.StartJob (single lock scope for check-and-set)
- Store TestRunnerApi reference with HideAndDontSave to prevent GC/serialization issues
* docs: update tool descriptions to prefer run_tests_async
- run_tests_async is now marked as preferred for long-running suites
- run_tests description notes it blocks and suggests async alternative
* docs: update README screenshot to v8.6 UI
* docs: add v8.6 UI screenshot
* Update README for MCP version and instructions for v8.7
* fix: handle preflight busy signals and derive job status from test results
- manage_asset, manage_gameobject, manage_scene now check preflight return
value and propagate busy/retry signals to clients (fixes Sourcery #1)
- TestJobManager.FinalizeCurrentJobFromRunFinished now sets job status to
Failed when resultPayload.Failed > 0, not always Succeeded (fixes Sourcery #2)
* fix: increase HTTP server startup timeout for dev mode
When 'Force fresh server install' is enabled, uvx uses --no-cache --refresh
which rebuilds the package and takes significantly longer to start.
- Increase timeout from 10s to 45s when dev mode is enabled
- Add informative log message explaining the longer startup time
- Show actual timeout value in warning message
* fix: derive job status from test results in FinalizeFromTask fallback
Apply same logic as FinalizeCurrentJobFromRunFinished: check result.Failed > 0
to correctly mark jobs as Failed when tests fail, even in the fallback path
when RunFinished callback is not delivered.
* Optimize run_tests to return summary by default, reducing token usage by 98%
- Add includeFailedTests parameter: returns only failed/skipped test details
- Add includeDetails parameter: returns all test details (original behavior)
- Default behavior now returns summary only (~150 tokens vs ~13k tokens)
- Make results field optional in Python schema for backward compatibility
Token savings:
- Default: ~13k tokens saved (98.9% reduction)
- With failures: minimal tokens (only non-passing tests)
- Full details: same as before when explicitly requested
This prevents context bloat for typical test runs where you only need
pass/fail counts, while still allowing detailed debugging when needed.
* Add warning when run_tests filters match no tests; fix test organization
TDD Feature:
- Add warning message when filter criteria match zero tests
- New RunTestsTests.cs validates message formatting logic
- Modified RunTests.cs to append "(No tests matched the specified filters)" when total=0
Test Organization Fixes:
- Move MCPToolParameterTests.cs from EditMode/ to EditMode/Tools/ (matches folder hierarchy)
- Fix inconsistent namespaces to MCPForUnityTests.Editor.{Subfolder}:
- MCPToolParameterTests: Tests.EditMode → MCPForUnityTests.Editor.Tools
- DomainReloadResilienceTests: Tests.EditMode.Tools → MCPForUnityTests.Editor.Tools
- Matrix4x4ConverterTests: MCPForUnityTests.EditMode.Helpers → MCPForUnityTests.Editor.Helpers
* Refactor test result message formatting
* Simplify RunTests warning assertions
* Tests: de-flake cold-start EditMode runs
- Make ManageScriptableObjectTests setup yield-based with longer Unity-ready timeout
- Mark DomainReloadResilienceTests explicit to avoid triggering domain reload during Run All
* Avoid blocking Claude CLI status checks on focus
* Fix Claude Code registration to remove existing server before re-registering
When registering with Claude Code, if a UnityMCP server already exists,
remove it first before adding the new registration. This ensures the
transport mode (HTTP vs stdio) is always updated to match the current
UseHttpTransport EditorPref setting.
Previously, if a stdio registration existed and the user tried to register
with HTTP, the command would fail with 'already exists' and the old stdio
configuration would remain unchanged.
* Fix Claude Code transport validation to parse CLI output format correctly
The validation code was incorrectly parsing the output of 'claude mcp get UnityMCP' by looking for JSON format ("transport": "http"), but the CLI actually returns human-readable text format ("Type: http"). This caused the transport mismatch detection to never trigger, allowing stdio to be selected in the UI while HTTP was registered with Claude Code.
Changes:
- Fix parsing logic to check for "Type: http" or "Type: stdio" in CLI output
- Add OnTransportChanged event to refresh client status when transport changes
- Wire up event handler to trigger client status refresh on transport dropdown change
This ensures that when the transport mode in Unity doesn't match what's registered with Claude Code, the UI will correctly show an error status with instructions to re-register.
* Fix Claude Code registration UI blocking and thread safety issues
This commit resolves three issues with Claude Code registration:
1. UI blocking: Removed synchronous CheckStatus() call after registration
that was blocking the editor. Status is now set immediately with async
verification happening in the background.
2. Thread safety: Fixed "can only be called from the main thread" errors
by capturing Application.dataPath and EditorPrefs.GetBool() on the main
thread before spawning async status check tasks.
3. Transport mismatch detection: Transport mode changes now trigger immediate
status checks to detect HTTP/stdio mismatches, instead of waiting for the
45-second refresh interval.
The registration button now turns green immediately after successful
registration without blocking, and properly detects transport mismatches
when switching between HTTP and stdio modes.
* Enforce thread safety for Claude Code status checks at compile time
Address code review feedback by making CheckStatusWithProjectDir thread-safe
by design rather than by convention:
1. Made projectDir and useHttpTransport parameters non-nullable to prevent
accidental background thread calls without captured values
2. Removed nullable fallback to EditorPrefs.GetBool() which would cause
thread safety violations if called from background threads
3. Added ArgumentNullException for null projectDir instead of falling back
to Application.dataPath (which is main-thread only)
4. Added XML documentation clearly stating threading contracts:
- CheckStatus() must be called from main thread
- CheckStatusWithProjectDir() is safe for background threads
5. Removed unreachable else branch in async status check code
These changes make it impossible to misuse the API from background threads,
with compile-time enforcement instead of runtime errors.
* Consolidate local HTTP Start/Stop and auto-start session
* HTTP improvements: Unity-owned server lifecycle + UI polish
* Deterministic HTTP stop via pidfile+token; spawn server in terminal
* Fix review feedback: token validation, host normalization, safer casts
* Fix stop heuristics edge cases; remove dead pid capture
* Fix unity substring guard in stop heuristics
* Fix local server cleanup and connection checks
* Fix read_console default limits; cleanup Unity-managed server vestiges
* Fix unfocused reconnect stalls; fast-fail retryable Unity commands
* Simplify PluginHub reload handling; honor run_tests timeout
* Fix Windows Claude CLI status check threading
* The default URL is already set when we call the function
* Remove placeholer for HTTP URL in the UI
When we load the UI, we use `HttpEndpointUtility.GetBaseUrl()`, so we don't need this
* Optimize tool loading so startup is fast again
We lazy load tools, remove the expensive AssetPath property, and reflect for only `McpForUnityToolAttribute`, so it's much faster.
A 6 second startup is now back to 400ms. Can still be optimised but this is good
* Remove .meta file from tests
The tests automatically cleans this up, so it likely got pushed by accident
* Add EditorPrefs management window for MCP configuration debugging
Meant to help with dev and testing, not so much the average user

* Fix test teardown to avoid dropping MCP bridge
CodexConfigHelperTests was calling MCPServiceLocator.Reset() in TearDown, which disposes the active bridge/transport during MCP-driven test runs. Replace with restoring only the mutated service (IPlatformService).

* Fix#478: Add Matrix4x4Converter to prevent Cinemachine serialization crash
The `get_components` action crashes Unity when serializing Cinemachine
camera components because Newtonsoft.Json accesses computed Matrix4x4
properties (lossyScale, rotation) that call ValidTRS() on non-TRS matrices.
This fix adds a safe Matrix4x4Converter that only accesses raw matrix
elements (m00-m33), avoiding the dangerous computed properties entirely.
Changes:
- Add Matrix4x4Converter to UnityTypeConverters.cs
- Register converter in GameObjectSerializer serializer settings
Tested with Cinemachine 3.1.5 on Unity 6 - get_components now returns
full component data without crashing.

* Add missing meta files
* Re-generate .meta files
It was for safety as some were AI generated before. Only minor changes were made
* Remove distribution settings and hardcode default localhost URL
Removes the McpDistributionSettings system that allowed different defaults for Asset Store vs git distributions. Hardcodes the default HTTP base URL to "http://localhost:8080" directly in HttpEndpointUtility and WebSocketTransportClient. Removes the setup window skip logic for remote defaults.
It didn't work in practice, best thing to do is replace the placeholder in the UXML

* Fix script path handling and FastMCP Context API usage
1. Fix script path doubling when Assets prefix is used
- ManageScript.TryResolveUnderAssets now properly handles both Assets and Assets/ prefixes
- Previously, paths like Assets/Script.cs would create files at Assets/Assets/Script.cs
- Now correctly strips the prefix and creates files at the intended location
2. Fix FastMCP Context API call in manage_asset
- Changed ctx.warn() to ctx.warning() to match FastMCP Context API
- Fixes AttributeError when manage_asset encounters property parse errors
- Affects ScriptableObject creation and other asset operations with invalid properties
* Fix manage_asset error handling to use ctx.error
Changed ctx.warning to ctx.error for property parse errors in manage_asset
tool to properly handle error cases. This ensures parse errors are reported
as errors rather than warnings, and fixes compatibility with FastMCP Context API.

* Update on Batch
Tested object generation/modification with batch and it works perfectly! We should push and let users test for a while and see
PS: I tried both VS Copilot and Claude Desktop. Claude Desktop works but VS Copilot does not due to the nested structure of batch. Will look into it more.

- StdioBridgeHost.cs: Refactor listener creation into helper method and update EditorPrefs on port fallback
- unity_instance_middleware.py: Narrow exception handling and preserve SystemExit/KeyboardInterrupt
- debug_request_context.py: Document that debug fields expose internal implementation details
* Fix: Harden Python detection on Windows to handle App Execution Aliases
* Refactor: Pre-resolve conflicts for McpConnectionSection and middleware
* Fix: Remove leftover merge conflict markers in StdioBridgeHost.cs
* fix: clarify create_script tool description regarding base64 encoding
* fix: improve python detection on macOS by checking specific Homebrew paths
* Fix duplicate SetEnabled call and improve macOS Python detection

Tackle the requests in Issue#267, tested and no bugs found.
(1)LLM can duplicate an gameobject based on request
(2)LLM can move a gameobject relative to another gameobject
* Fix: HTTP/Stdio transport routing and middleware session persistence
- Ensure session persistence for stdio transport by using stable client_id/global fallback.
- Fix Nagle algorithm latency issues by setting TCP_NODELAY.
- Cleanup duplicate logging and imports.
- Resolve C# NullReferenceException in EditorWindow health check.
* Fix: thread-safe middleware singleton and re-enable repo stats schedule
* Temp Update on Material Assignment
Previously it was shader assignment by request or iterative order from URP to Unlit, but LLM usually assign Standard in a URP setting.
This small fix introduce the helper to resolve some of the conflicts, while give warnings in the log to show if the user is creating a shader in a non-compatible setting.
* Update RenderPipelineUtility.cs
* fix: Changed flag management to EditorPrefs
* refactor: Improve code readability and error handling in MCP window toggle
