# Declaw

{% embed url="<https://www.computesdk.com/benchmarks/sandboxes/declaw/>" %}

Declaw provider for ComputeSDK

Declaw runs Firecracker microVMs with a built-in security stack: PII scanning, prompt-injection defense, TLS-intercepting egress proxy, and per-sandbox network policies.

## Installation & Setup

```bash
npm install @computesdk/declaw
```

Add your Declaw credentials to a `.env` file:

```bash
DECLAW_API_KEY=your_declaw_api_key
```

API keys must start with `dcl_`.

## Usage

```typescript
import { declaw } from '@computesdk/declaw';

const compute = declaw({
  apiKey: process.env.DECLAW_API_KEY,
});

// Create sandbox
const sandbox = await compute.sandbox.create();

// Run a command
const result = await sandbox.runCommand('node -v');
console.log(result.stdout); // v20.x.x

// Clean up
await sandbox.destroy();
```

### Configuration Options

```typescript
interface DeclawConfig {
  /** Declaw API key - if not provided, will use DECLAW_API_KEY env var */
  apiKey?: string;
  /** API domain - if not provided, will use DECLAW_DOMAIN env var */
  domain?: string;
  /** Default create-time timeout in milliseconds (default: 300000) */
  timeout?: number;
}
```

When `domain` is not set (and `DECLAW_DOMAIN` is not set), the provider passes `undefined` to the underlying `@declaw/sdk`. The effective default of `api.declaw.ai` is applied by `@declaw/sdk`, not by this provider.

## Templates

`templateId` maps to a Declaw template alias. Defaults to `node` (Ubuntu 22.04 + Node.js 20).

**Built-in templates:**

* `base`
* `node` (default)
* `python`
* `code-interpreter`
* `ai-agent`
* `mcp-server`
* `web-dev`
* `devops`

```typescript
const sandbox = await compute.sandbox.create({
  templateId: 'python',
});
```

Custom templates can be built through the Declaw CLI — see the [Declaw docs](https://docs.declaw.ai/).

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.computesdk.com/providers/declaw.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
