| name | gameobject-find |
| description | 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.
Path-scoped reads (token-saving): supply 'paths' (a list of paths) to read only the listed fields/elements via Reflector.TryReadAt, or 'viewQuery' (a ViewQuery) to navigate to a subtree and/or filter by name regex / max depth / type via Reflector.View. When either is supplied, the result populates 'Data' on the returned GameObjectData and overrides 'includeData' (which would otherwise produce a full recursive serialization). These two parameters are mutually exclusive — supply at most one.
Path syntax: 'fieldName', 'nested/field', 'arrayField/[i]', 'dictField/[key]'. Leading '#/' is stripped. |
GameObject / Find
How to Call
unity-mcp-cli run-tool gameobject-find --input '{
"gameObjectRef": "string_value",
"includeData": false,
"includeComponents": false,
"includeBounds": false,
"includeHierarchy": false,
"hierarchyDepth": 0,
"paths": "string_value",
"viewQuery": "string_value"
}'
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. |
paths | any | No | Optional. List of paths to read individually via Reflector.TryReadAt. When supplied, replaces 'includeData'-style full serialization with a path-scoped aggregate. Path syntax: 'fieldName', 'nested/field', 'arrayField/[i]', 'dictField/[key]'. Mutually exclusive with 'viewQuery'. |
viewQuery | any | No | Optional. View-query filter routed through Reflector.View. When supplied, replaces 'includeData'-style full serialization with the filtered subtree. Mutually exclusive with 'paths'. |
