Unity MCP skills

Capture a screenshot from the Unity Editor Scene View at the requested size. Renders via the Scene View's active camera onto a temporary `RenderTexture`. Requires an open Scene View.

List all shaders available in the project assets and packages, sorted by name. Use this to discover a valid `shaderName` for 'assets-material-create'.

Return script execution timing (frame time, fixed dt, time scale, frame count, runtime) plus Mono / GC memory usage in MB.

Add one or more Components to a GameObject in the opened Prefab or active Scene. Component types are looked up by full name (with namespace) or by class-name fallback. Use 'gameobject-find' to locate the host GameObject and 'gameobject-component-list-all' to discover valid component type names.

List all known profiler module names with their local 'enabled' bookkeeping flag.

Write a `.cs` script file (create or overwrite) with the provided C# code. Validates syntax via Roslyn before write — invalid code is rejected with error details and the file is left untouched. Refreshes the AssetDatabase and delivers the final result via `requestId` after Unity finishes the triggered compilation. Use 'script-read' to inspect existing content first.

Open a Unity scene asset in Single or Additive mode. Returns the post-open list of all opened scenes. Use 'assets-find' to locate the scene asset first.

Search the Unity asset database using a search filter string. The filter accepts names, labels (`l:`), types (`t:`), AssetBundles (`b:`), areas (`a:`), and globs (`glob:`). See the body for the full filter syntax.

Compiles and executes C# code dynamically using Roslyn. Supports a full-code mode (default) and a body-only mode — see the skill body for the difference and for how to pass Unity object references as parameters.

Regenerate every `SKILL.md` from the project's currently-registered MCP tools into the configured skills folder (or a project-relative override path). Writes the YAML `description:` from `[AiSkillDescription]` and the body from `[AiSkillBody]`.

List all UPM packages installed in the Unity project — name, version, source, description. Optionally filter by source (registry, embedded, local, git, built-in, local tarball), by name/display/description substring, and by direct-dependency-only.

Execute Unity tests (`EditMode` or `PlayMode`) and return per-test results. Supports filtering by test assembly, namespace, class, and method. Refreshes the AssetDatabase first; defers execution across domain reloads if scripts changed. Precondition: every open scene must be saved — dirty scenes abort the run.

Capture the current frame's timing info (delta time, FPS, frame counts, runtime). Snapshot only — historical frames live in Unity's Profiler window.

Call a C# method by reflection — including private methods. Requires a method schema obtained via 'reflection-method-find'. Supports static methods, instance methods (with optional target deserialization), and main-thread / off-thread execution.

Review and resolve PR comments from GitHub. Validates each comment, fixes legitimate issues.

Find C# methods across every loaded assembly by name / type / parameters — including private methods. Returns serialized `MethodData` entries usable as schemas for 'reflection-method-call'.

Move or rename assets at the given project paths. Refreshes the AssetDatabase at the end. Use 'assets-find' to locate the assets first.

Get information about the current Selection in the Unity Editor — active object, active transform, selected GameObjects, transforms, instance IDs, and asset GUIDs (each enrichment is opt-in). Pair with 'editor-selection-set' to change the selection.

Retrieve the list of root GameObjects in the specified opened scene (or the active scene when `openedSceneName` is empty). Supports token-saving path-scoped reads over the root-GameObjects array via `paths` or `viewQuery`. Use 'scene-list-opened' to enumerate scenes.

Modify a Unity `UnityEngine.Object`'s serializable fields/properties. Three modification surfaces are available (`objectDiff`, `pathPatches`, `jsonPatch`) — see the skill body. Use 'object-get-data' first to inspect the object structure.

Destroy a GameObject (and all nested children) in the currently opened Prefab or active Scene. Returns the destroyed GameObject's name, path, and instance ID for confirmation. Use 'gameobject-find' to locate the target first.

Refresh the Unity AssetDatabase. Use after files were added or updated outside of the Unity API, or to force script recompilation when a '.cs' file changed. Returns a processing/success response and waits for compilation when triggered.

Enable Unity's runtime profiler and open the Profiler window. Idempotent: calling when already enabled returns the current enabled state without error.

Save the currently opened prefab edit stage back to its prefab asset without exiting the stage. Pair with 'assets-prefab-open' to enter the edit mode first.
