object-get-data

name

object-get-data

description

Get data of the specified Unity Object. Returns serialized data of the object including its properties and fields. If need to modify the data use 'object-modify' 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 object is serialized as before (backwards compatible). Path syntax: 'fieldName', 'nested/field', 'arrayField/[i]', 'dictField/[key]'. Leading '#/' is stripped.

Object / Get Data

How to Call

unity-mcp-cli run-tool object-get-data --input '{
  "objectRef": "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 object-get-data --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool object-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
objectRef	any	Yes	Reference to UnityEngine.Object instance. It could be GameObject, Component, Asset, etc. Anything extended from UnityEngine.Object.
paths	any	No	Optional. List of paths to read individually via Reflector.TryReadAt. Each path may target a different depth. 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'.
