version: "1.0.0" name: assets-prefab-save description: Save the currently opened prefab edit stage back to its prefab asset without exiting the stage. Pair with 'assets-prefab-open' to enter the edit mode first.

Assets / Prefab / Save

Save a prefab. Use it when you are in prefab editing mode in Unity Editor. Use 'assets-prefab-open' tool to open a prefab first.

Behavior

Calls PrefabUtility.SaveAsPrefabAsset on the current prefab stage's contents root, clears the stage's dirtiness flag, repaints editor windows, and returns an AssetObjectRef to the saved prefab. Throws when no prefab stage is currently open.

How to Call

bash

unity-mcp-cli run-tool assets-prefab-save --input '{
  "nothing": "string_value"
}'

For complex input (multi-line strings, code), save the JSON to a file and use:
```bash
unity-mcp-cli run-tool assets-prefab-save --input-file args.json
```
Or pipe via stdin (recommended):
```bash
unity-mcp-cli run-tool assets-prefab-save --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.
