# Computer

Sandboxes that run a desktop environment can expose screenshot, mouse, and keyboard control. The workspace registers computer tools when a statically configured sandbox supports the computer capability.

[`DaytonaSandbox`](https://mastra.ai/integrations/sandboxes/daytona) and [`E2BDesktopSandbox`](https://mastra.ai/integrations/sandboxes/e2b-desktop) support this capability. Other sandbox backends don't register the computer tools. Resolver-backed sandboxes don't register them because the workspace can't inspect the resolved sandbox's capabilities when it creates the tool list.

## Computer tools

| Tool                       | Does                                                                             |
| -------------------------- | -------------------------------------------------------------------------------- |
| `computer_screenshot`      | Captures the desktop as a PNG image and returns it to the model as native media. |
| `computer_click`           | Presses and releases the left mouse button at pixel coordinates.                 |
| `computer_double_click`    | Presses the left mouse button twice at pixel coordinates.                        |
| `computer_right_click`     | Presses and releases the right mouse button at pixel coordinates.                |
| `computer_move_mouse`      | Moves the cursor to pixel coordinates without pressing a button.                 |
| `computer_drag`            | Presses, drags, and releases between two points.                                 |
| `computer_type`            | Types text into the focused element.                                             |
| `computer_press_key`       | Presses a key or key combination, such as `Enter` or `ctrl+s`.                   |
| `computer_scroll`          | Scrolls up or down.                                                              |
| `computer_get_screen_info` | Gets the screen dimensions and cursor position.                                  |
| `computer_wait`            | Waits for the interface to settle.                                               |

## Configure computer tools

Action tools take a screenshot after each action by default. Configure the screenshot behavior for each tool:

```typescript
import { Workspace, WORKSPACE_TOOLS } from '@mastra/core/workspace'
import { E2BDesktopSandbox } from '@mastra/e2b-desktop'

const workspace = new Workspace({
  sandbox: new E2BDesktopSandbox(),
  tools: {
    [WORKSPACE_TOOLS.COMPUTER.CLICK]: {
      screenshotAfterAction: true,
      screenshotDelayMs: 1000,
    },
    [WORKSPACE_TOOLS.COMPUTER.TYPE]: {
      requireApproval: true,
    },
  },
})
```

Computer tools accept the same per-tool `enabled` and `requireApproval` configuration as other workspace tools.
