// Get asset data from the asset file in the Unity project — every serializable field and property. Supports token-saving path-scoped reads via `paths` or `viewQuery`. Use 'assets-find' to find the asset first.
Copy assets at given paths and store them at new paths. Refreshes the AssetDatabase at the end. Use 'assets-find' to locate the source assets first.
Create a new folder under a parent folder inside 'Assets/'. The parent path must start with 'Assets/' and every intermediate folder in it must already exist. Refreshes the AssetDatabase at the end and returns the GUID(s) of the created folder(s).
Delete the assets at the given project paths. Refreshes the AssetDatabase at the end. Use 'assets-find' to locate the assets first.
Search the built-in assets of the Unity Editor (located at Resources/unity_builtin_extra). Filters by name and/or type; built-in assets have no GUID so GUID-based lookups are not supported.
Search the Unity asset database using a search filter string. The filter accepts names, labels (`l:`), types (`t:`), AssetBundles (`b:`), areas (`a:`), and globs (`glob:`). See the body for the full filter syntax.
Modify an asset file in the project. Use 'assets-get-data' first to inspect the asset structure before modifying. Not allowed to modify asset files in the 'Packages/' folder — modify them in 'Assets/'. Three modification surfaces are available (content, pathPatches, jsonPatch) — see the skill body for details.

| description | Get asset data from the asset file in the Unity project — every serializable field and property. Supports token-saving path-scoped reads via `paths` or `viewQuery`. Use 'assets-find' to find the asset first. |
Get asset data from the asset file in the Unity project. It includes all serializable fields and properties of the asset. Use 'assets-find' tool to find asset before using this tool.
Supply paths (a list of paths) to read only the listed fields/elements via Reflector.TryReadAt, or viewQuery (a ViewQuery) to navigate to a subtree and/or filter by name regex / max depth / type via Reflector.View. These two parameters are mutually exclusive — supply at most one. When neither is supplied the full asset is serialized (backwards compatible).
fieldName, nested/field, arrayField/[i], dictField/[key]. Leading #/ is stripped.
unity-mcp-cli run-tool assets-get-data --input '{
"assetRef": "string_value",
"paths": "string_value",
"viewQuery": "string_value"
}'
For complex input (multi-line strings, code), save the JSON to a file and use:
unity-mcp-cli run-tool assets-get-data --input-file args.jsonOr pipe via stdin (recommended):
unity-mcp-cli run-tool assets-get-data --input-file - <<'EOF' {"param": "value"} EOF
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.
| Name | Type | Required | Description |
|---|---|---|---|
assetRef | 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. |
paths | any | No | Optional. List of paths to read individually via Reflector.TryReadAt. Path syntax: 'fieldName', 'nested/field', 'arrayField/[i]', 'dictField/[key]'. Mutually exclusive with 'viewQuery'. |
viewQuery | any | No | Optional. View-query filter routed through Reflector.View — combines a starting Path, a case-insensitive NamePattern regex, MaxDepth, and an optional TypeFilter. Mutually exclusive with 'paths'. |
