/object-get-data

name: object-get-data
description: Get serialized data for a Unity `UnityEngine.Object` — all serializable fields and properties. Supports token-saving path-scoped reads via `paths` or `viewQuery`. Pair with 'object-modify' when you need to write back.

Object / Get Data

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 (backwards compatible).

Path syntax

`fieldName`, `nested/field`, `arrayField/[i]`, `dictField/[key]`. Leading `#/` is stripped.

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: > ```bash > unity-mcp-cli run-tool object-get-data --input-file args.json > ``` > > Or pipe via stdin (recommended): > ```bash > 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'. |
