name: gameobject-component-list-all
description: List the fully-qualified C# type names of every concrete `UnityEngine.Component` subclass available in the project. Paginated (default 5/page, max 500). Use this to find a valid `componentName` for 'gameobject-component-add'.

# GameObject / Component / List All

List C# class names extended from UnityEngine.Component. Use this to find component type names for 'gameobject-component-add' tool. Results are paginated to avoid overwhelming responses.

## Inputs

- `search` (optional) — case-insensitive substring filter on type names.
- `page` (default 0, 0-based) — page index.
- `pageSize` (default 5, range 1..500) — items per page.

## Behavior

Enumerates `AllComponentTypes` (every non-abstract subclass of `UnityEngine.Component`), filters by `search` if supplied, then returns a `ComponentListResult` containing the requested page plus `TotalCount` / `TotalPages` so the caller can iterate.

## How to Call

```bash
unity-mcp-cli run-tool gameobject-component-list-all --input '{
  "search": "string_value",
  "page": 0,
  "pageSize": 0
}'
```

> For complex input (multi-line strings, code), save the JSON to a file and use:
> ```bash
> unity-mcp-cli run-tool gameobject-component-list-all --input-file args.json
> ```
>
> Or pipe via stdin (recommended):
> ```bash
> unity-mcp-cli run-tool gameobject-component-list-all --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 |
|------|------|----------|-------------|
| `search` | `string` | No | Substring for searching components. Could be empty. |
| `page` | `integer` | No | Page number (0-based). Default is 0. |
| `pageSize` | `integer` | No | Number of items per page. Default is 5. Max is 500. |
