Scene / Unload

Unload scene from the Opened scenes in Unity Editor. Use 'scene-list-opened' tool to get the list of all opened scenes.

Inputs

• name — required non-empty scene name. Must match an opened scene; otherwise throws.

Behavior

Runs SceneManager.UnloadSceneAsync on the main thread and awaits completion. Returns an UnloadSceneResult containing the scene name and an AssetObjectRef to its asset (or null if the scene was not backed by an asset on disk).

How to Call

unity-mcp-cli run-tool scene-unload --input '{
  "name": "string_value"
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

unity-mcp-cli run-tool scene-unload --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool scene-unload --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
name	string	Yes	Name of the loaded scene.
