The Claude Computer Use integration runs Anthropic's vision-based agent loop on a Steel browser session. Claude takes screenshots through Steel, decides the next action (click, type, scroll), and Steel executes it, so you can automate complex web tasks without writing custom selectors.

It pairs well with Steel's anti-bot capabilities, proxy support, and sandboxed environments.

### Requirements

*   **Anthropic API Key**: A Claude 4 model with computer use
*   **Steel API Key**: Active Steel subscription
*   **Runtime**: Python 3.10+ or Node.js 20+
*   **Note**: Anthropic's computer-use tool is in beta

### Connect Steel to Claude

Steel's `sessions.computer` API takes screenshots and executes actions; pair it with Claude's `computer_20251124` tool (with the `computer-use-2025-11-24` beta header):

```typescript Typescript -wc
import { Steel } from "steel-sdk";

const steel = new Steel({ steelAPIKey: STEEL_API_KEY });
const session = await steel.sessions.create({
  dimensions: { width: 1024, height: 768 },
});

// Take a screenshot via Steel
const { base64_image } = await steel.sessions.computer(session.id, {
  action: "take_screenshot",
});

// Send to Claude with the computer-use tool, then route Claude's
// returned actions back through `steel.sessions.computer({ action: ... })`.
```

### FAQ

### Do I need Playwright or CSS selectors to use Claude Computer Use with Steel?

No — Claude's computer-use loop is vision-based. Claude looks at screenshots, decides actions like click, type, or scroll, and Steel executes them through its `sessions.computer` API, so there are no custom selectors to write.

### How do I connect Claude Computer Use to a Steel browser session?

Create a session with explicit `dimensions` (the example uses 1024x768), take screenshots via `steel.sessions.computer(session.id, { action: "take_screenshot" })`, send the `base64_image` to Claude's `computer_20251124` tool, and route Claude's returned actions back through `steel.sessions.computer({ action: ... })`.

### Does Claude Computer Use work with Steel's proxies, stealth mode, and CAPTCHA solving?

Yes — the page notes it pairs well with Steel's anti-bot capabilities, proxy support, and sandboxed environments. These are enabled at session creation (e.g. `useProxy`, `solveCaptcha`, `stealthConfig`) and don't change the agent loop.

### How does the screenshot/action loop actually work?

Steel takes a screenshot, you send it to Claude with the computer-use tool, Claude returns the next action (click, type, scroll), and Steel executes it via `sessions.computer` — then you screenshot again and repeat until the task completes.
