Return the current FastMCP request context details (client_id, session_id, and meta dump).

Execute arbitrary C# code inside the Unity Editor. The code runs as a method body with access to UnityEngine and UnityEditor namespaces. Use 'return' to send data back. Compiled in-memory — no script files created. Actions: execute (run code), get_history (list past executions), replay (re-run a history entry), clear_history. NOTE: safety_checks blocks known dangerous patterns but is not a full sandbox. Compiler options: 'auto' (Roslyn if available, else CodeDom), 'roslyn' (C# 12+, requires Microsoft.CodeAnalysis), 'codedom' (C# 6 only).

Execute a Unity menu item by path.

Search for GameObjects in the scene by name, tag, layer, component type, or path. Returns instance IDs only (paginated). Then use mcpforunity://scene/gameobject/{id} resource for full data, or mcpforunity://scene/gameobject/{id}/components for component details. For CRUD operations (create/modify/delete), use manage_gameobject instead.

Performs asset operations (import, create, modify, delete, etc.) in Unity.

Tip (payload safety): for action="search", prefer paging (page_size, page_number) and keep generate_preview=false (previews can add large base64 blobs).

Manage cameras (Unity Camera + Cinemachine). Works without Cinemachine using basic Camera; unlocks presets, pipelines, and blending when Cinemachine is installed. Use ping to check Cinemachine availability.

SETUP:

• ping: Check if Cinemachine is available

• ensure_brain: Ensure CinemachineBrain exists on main camera

• get_brain_status: Get Brain state (active camera, blend, etc.)

CAMERA CREATION:

• create_camera: Create camera with preset (third_person, freelook, follow, dolly, static, top_down, side_scroller). Falls back to basic Camera without Cinemachine.

CAMERA CONFIGURATION:

• set_target: Set Follow and/or LookAt targets on a camera

• set_priority: Set camera priority for Brain selection

• set_lens: Configure lens (fieldOfView, nearClipPlane, farClipPlane, orthographicSize, dutch)

• set_body: Configure Body component (bodyType to swap, plus component properties)

• set_aim: Configure Aim component (aimType to swap, plus component properties)

• set_noise: Configure Noise component (amplitudeGain, frequencyGain)

EXTENSIONS:

• add_extension: Add extension (extensionType: CinemachineConfiner2D, CinemachineDeoccluder, CinemachineImpulseListener, CinemachineFollowZoom, CinemachineRecomposer, etc.)

• remove_extension: Remove extension by type

CAMERA CONTROL:

• set_blend: Configure default blend (style: Cut/EaseInOut/Linear/etc., duration)

• force_camera: Override Brain to use specific camera

• release_override: Release camera override

• list_cameras: List all cameras with status

CAPTURE:

• screenshot: Capture a screenshot. By default (no camera specified) uses ScreenCapture API, which captures all render layers including Screen Space - Overlay UI canvases. Specifying a camera uses direct camera rendering, which EXCLUDES Screen Space - Overlay canvases (use only when you need a specific viewpoint without UI). Supports include_image=true for inline base64 PNG, batch='surround' for 6-angle contact sheet, batch='orbit' for configurable grid, view_target/view_position for positioned capture, and capture_source='scene_view' to capture the active Unity Scene View viewport.

• screenshot_multiview: Shorthand for screenshot with batch='surround' and include_image=true.

Controls and queries the Unity editor's state and settings. Read-only actions: telemetry_status, telemetry_ping. Modifying actions: play, pause, stop, set_active_tool, add_tag, remove_tag, add_layer, remove_layer, deploy_package, restore_package, undo, redo. For prefab editing (open/save/close prefab stage), use manage_prefabs. deploy_package copies the configured MCPForUnity source folder into the project's installed package location (triggers recompile, no confirmation dialog). restore_package reverts to the pre-deployment backup. undo/redo perform Unity editor undo/redo and return the affected group name.

Performs CRUD operations on GameObjects. Actions: create, modify, delete, duplicate, move_relative, look_at. NOT for searching — use the find_gameobjects tool to search by name/tag/layer/component/path. NOT for component management — use the manage_components tool (add/remove/set_property) or mcpforunity://scene/gameobject/{id}/components resource (read).

Manage Unity packages: query, install, remove, embed, and configure registries.

QUERY (read-only):

• list_packages: List all installed packages

• search_packages: Search Unity registry by keyword

• get_package_info: Get details about a specific installed package

• ping: Check package manager availability

• status: Poll async job status (job_id required for list/search; optional for add/remove/embed)

INSTALL/REMOVE:

• add_package: Install a package (name, name@version, git URL, or file: path)

• remove_package: Remove a package (checks dependents; use force=true to override)

REGISTRIES:

• list_registries: List all scoped registries

• add_registry: Add a scoped registry (e.g., OpenUPM)

• remove_registry: Remove a scoped registry

UTILITY:

• embed_package: Copy package to local Packages/ for editing

• resolve_packages: Force re-resolution of all packages

Performs CRUD operations on Unity scenes. Read-only actions: get_hierarchy, get_active, get_build_settings, get_loaded_scenes, scene_view_frame. Modifying actions: create (with optional template), load (with optional additive flag), save, close_scene, set_active_scene, move_to_scene, validate (with optional auto_repair). For build settings management (add/remove/enable scenes), use manage_build(action='scenes'). For screenshots, use manage_camera (screenshot, screenshot_multiview actions).

Request a Unity asset database refresh and optionally a script compilation. Can optionally wait for readiness.

Gets messages from or clears the Unity Editor console. Defaults to 10 most recent entries. Use page_size/cursor for paging. Note: For maximum client compatibility, pass count as a quoted string (e.g., '5'). The 'get' action is read-only; 'clear' modifies ephemeral UI state (not project data).

Set the active Unity instance for this client/session. Accepts Name@hash, hash prefix, or port number (stdio only).

Inspect Unity's live C# API via reflection. Use this to verify that classes, methods, and properties exist before writing C# code — training data may be wrong or outdated.

Actions:

• get_type: Member summary (names only) for a class. Requires class_name.

• get_member: Full signature detail for one member. Requires class_name + member_name.

• search: Type name search across loaded assemblies. Requires query. Optional scope.
