For local development, run Sandbox Agent directly on your machine.

## With the CLI

```bash
# Install
curl -fsSL https://releases.rivet.dev/sandbox-agent/0.2.x/install.sh | sh

# Run
sandbox-agent server --no-token --host 127.0.0.1 --port 2468
```

Or with npm/Bun:

<Tabs>
  <Tab title="npx">
    ```bash
    npx @sandbox-agent/cli@0.2.x server --no-token --host 127.0.0.1 --port 2468
    ```
  </Tab>
  <Tab title="bunx">
    ```bash
    bunx @sandbox-agent/cli@0.2.x server --no-token --host 127.0.0.1 --port 2468
    ```
  </Tab>
</Tabs>

## With the TypeScript SDK

The SDK can spawn and manage the server as a subprocess:

```typescript
import { SandboxAgent } from "sandbox-agent";

const sdk = await SandboxAgent.start();

const session = await sdk.createSession({
  agent: "claude",
});

await session.prompt([
  { type: "text", text: "Summarize this repository." },
]);

await sdk.dispose();
```

This starts the server on an available local port and connects automatically.
