Editor / Selection / Get

Get information about the current Selection in the Unity Editor. Use 'editor-selection-set' tool to set the selection.

Toggles (default off where indicated to keep responses small)

• includeGameObjects (default false) — populate GameObjects[].
• includeTransforms (default false) — populate Transforms[] as ComponentRefs.
• includeInstanceIDs (default false) — populate InstanceIDs[].
• includeAssetGUIDs (default false) — populate AssetGUIDs[] from project-window selection.
• includeActiveObject (default true) — populate ActiveObject as a generic ObjectRef.
• includeActiveTransform (default true) — populate ActiveTransform as a ComponentRef.

ActiveGameObject and ActiveInstanceID are always populated.

How to Call

unity-mcp-cli run-tool editor-selection-get --input '{
  "includeGameObjects": false,
  "includeTransforms": false,
  "includeInstanceIDs": false,
  "includeAssetGUIDs": false,
  "includeActiveObject": false,
  "includeActiveTransform": false
}'

For complex input (multi-line strings, code), save the JSON to a file and use: ``bash unity-mcp-cli run-tool editor-selection-get --input-file args.json ``

>

Or pipe via stdin (recommended): ``bash unity-mcp-cli run-tool editor-selection-get --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.
