assets-get-data

name

assets-get-data

description

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. Path-scoped reads (token-saving): 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 as before (backwards compatible). Path syntax: 'fieldName', 'nested/field', 'arrayField/[i]', 'dictField/[key]'. Leading '#/' is stripped.

Assets / Get Data

How to Call

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.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool assets-get-data --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
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'.
