Duplicate GameObjects in opened Prefab or in a Scene. Use 'gameobject-find' tool to find the target GameObjects first.
unity-mcp-cli run-tool gameobject-duplicate --input '{
"gameObjectRefs": "string_value"
}'
For complex input (multi-line strings, code), save the JSON to a file and use:
unity-mcp-cli run-tool gameobject-duplicate --input-file args.jsonOr pipe via stdin (recommended):
unity-mcp-cli run-tool gameobject-duplicate --input-file - <<'EOF' {"param": "value"} EOF
If unity-mcp-cli is not found, either install it globally () or use instead.
Read the /unity-initial-setup skill for detailed installation instructions.
npm install -g unity-mcp-clinpx unity-mcp-cli| Name | Type | Required | Description |
|---|---|---|---|
gameObjectRefs | any | Yes | Array of GameObjects in opened Prefab or in the active Scene. |
