Gameobject Component Get

name: gameobject-component-get
description: Get detailed information about a specific Component on a GameObject — type, enabled state, and (optionally) serialized fields and properties. Supports token-saving path-scoped reads via `paths` or `viewQuery`. Use 'gameobject-find' to list components first.

# GameObject / Component / Get

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.

## Inputs

- `gameObjectRef` — the host GameObject.
- `componentRef` — the specific component to inspect (matched by index or instance ID).
- `includeFields` (default `true`) — populate the legacy `Fields` list.
- `includeProperties` (default `true`) — populate the legacy `Properties` list.
- `deepSerialization` (default `false`) — when populating legacy lists, recurse into nested members.

## 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, and the legacy `Fields`/`Properties` lists are skipped. 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

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