For complex input (multi-line strings, code), save the JSON to a file and use:
unity-mcp-cli run-tool gameobject-find --input-file args.json
Or pipe via stdin (recommended):
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.
