Agent skill

gameobject-find

Finds specific GameObject by provided information in opened Prefab or in a Scene. First it looks for the opened Prefab, if any Prefab is opened it looks only there ignoring a scene. If no opened Prefab it looks into current active scene. Returns GameObject information and its children. Also, it returns Components preview just for the target GameObject.

GameObject / Find

How to Call

bash
unity-mcp-cli run-tool gameobject-find --input '{
  "gameObjectRef": "string_value",
  "includeData": false,
  "includeComponents": false,
  "includeBounds": false,
  "includeHierarchy": false,
  "hierarchyDepth": 0
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

bash
unity-mcp-cli run-tool gameobject-find --input-file args.json

Or pipe via stdin (recommended):

bash
unity-mcp-cli run-tool gameobject-find --input-file - <<'EOF'
{"param": "value"}
EOF

Troubleshooting

If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead. Read the /unity-initial-setup skill for detailed installation instructions.

Input

Name Type Required Description
gameObjectRef any Yes Find GameObject in opened Prefab or in the active Scene.
includeData boolean No Include editable GameObject data (tag, layer, etc).
includeComponents boolean No Include attached components references.
includeBounds boolean No Include 3D bounds of the GameObject.
includeHierarchy boolean No Include hierarchy metadata.
hierarchyDepth integer No Determines the depth of the hierarchy to include. 0 - means only the target GameObject. 1 - means to include one layer below.
