Scene / List Opened

Returns the list of currently opened scenes in Unity Editor. Use 'scene-get-data' tool to get detailed information about a specific scene.

Behavior

Maps OpenedScenes through ToSceneDataShallow() on the main thread and returns the resulting array. No filtering or pagination — every opened scene is included.

How to Call

unity-mcp-cli run-tool scene-list-opened --input '{
  "nothing": "string_value"
}'

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

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

Or pipe via stdin (recommended):

unity-mcp-cli run-tool scene-list-opened --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.
