assets-prefab-close

# Assets / Prefab / Close Close currently opened prefab. Use it when you are in prefab editing mode in Unity Editor. Use 'assets-prefab-open' tool to open a prefab first. ## Inputs - `save` (default `true`) — when `true`, calls `PrefabUtility.SaveAsPrefabAsset` before exiting the stage; when `false`, the save is skipped. The prefab stage's dirtiness is always cleared at the end, so any unsaved changes are discarded when `save` is `false`. ## Behavior Throws when no prefab stage is currently open. Returns an `AssetObjectRef` for the closed prefab asset. ## How to Call ```bash unity-mcp-cli run-tool assets-prefab-close --input '{ "save": false }' ``` > For complex input (multi-line strings, code), save the JSON to a file and use: > ```bash > unity-mcp-cli run-tool assets-prefab-close --input-file args.json > ``` > > Or pipe via stdin (recommended): > ```bash > unity-mcp-cli run-tool assets-prefab-close --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.
