Scene / Open

How to Call

bash
unity-mcp-cli run-tool scene-open --input '{
  "sceneRef": "string_value",
  "loadSceneMode": "string_value"
}'

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

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

Or pipe via stdin (recommended):

bash
unity-mcp-cli run-tool scene-open --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
sceneRef any Yes Reference to UnityEngine.Object asset instance. It could be Material, ScriptableObject, Prefab, and any other Asset. Anything located in the Assets and Packages folders.
loadSceneMode string No Open scene mode. Single: closes the current scenes and opens a new one. Additive: keeps the current scene and opens additional one.
