gameobject-component-get

name

gameobject-component-get

description

Get detailed information about a specific Component on a GameObject. Returns component type, enabled state, and optionally serialized fields and properties. Use this to inspect component data before modifying it. Use 'gameobject-find' tool to get the list of all components on the GameObject. 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. The result is returned in the 'View' field of the response. These two parameters are mutually exclusive — supply at most one. Path syntax: 'fieldName', 'nested/field', 'arrayField/[i]', 'dictField/[key]'. Leading '#/' is stripped.

How to Call

unity-mcp-cli run-tool gameobject-component-get --input '{
  "gameObjectRef": "string_value",
  "componentRef": "string_value",
  "includeFields": false,
  "includeProperties": false,
  "deepSerialization": false,
  "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 gameobject-component-get --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool gameobject-component-get --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
gameObjectRef	any	Yes	Find GameObject in opened Prefab or in the active Scene.
componentRef	any	Yes	Component reference. Used to find a Component at GameObject.
includeFields	boolean	No	Include serialized fields of the component.
includeProperties	boolean	No	Include serialized properties of the component.
deepSerialization	boolean	No	Performs deep serialization including all nested objects. Otherwise, only serializes top-level members.
paths	any	No	Optional. List of paths to read individually via Reflector.TryReadAt. When supplied, the legacy 'Fields'/'Properties' lists are skipped and the result is returned in 'View'. Path syntax: 'fieldName', 'nested/field', 'arrayField/[i]', 'dictField/[key]'. Mutually exclusive with 'viewQuery'.
viewQuery	any	No	Optional. View-query filter routed through Reflector.View. When supplied, the legacy 'Fields'/'Properties' lists are skipped and the filtered subtree is returned in 'View'. Mutually exclusive with 'paths'.
