Assets / Prefab / Save

Save a prefab. Use it when you are in prefab editing mode in Unity Editor. Use 'assets-prefab-open' tool to open a prefab first.

Behavior

Calls PrefabUtility.SaveAsPrefabAsset on the current prefab stage's contents root, clears the stage's dirtiness flag, repaints editor windows, and returns an AssetObjectRef to the saved prefab. Throws when no prefab stage is currently open.

How to Call

unity-mcp-cli run-tool assets-prefab-save --input '{
  "nothing": "string_value"
}'
