description: "Deploy Sandbox Agent inside an E2B sandbox."

|
|
|
|
## Prerequisites
|
|
|
|
- `E2B_API_KEY`
|
|
- `ANTHROPIC_API_KEY` or `OPENAI_API_KEY`
|
|
|
|
## TypeScript example
|
|
|
|
```bash
|
|
npm install sandbox-agent@0.4.x @e2b/code-interpreter
|
|
```
|
|
|
|
```typescript
|
|
import { SandboxAgent } from "sandbox-agent";
|
|
import { e2b } from "sandbox-agent/e2b";
|
|
|
|
const envs: Record<string, string> = {};
|
|
if (process.env.ANTHROPIC_API_KEY) envs.ANTHROPIC_API_KEY = process.env.ANTHROPIC_API_KEY;
|
|
if (process.env.OPENAI_API_KEY) envs.OPENAI_API_KEY = process.env.OPENAI_API_KEY;
|
|
const template = process.env.E2B_TEMPLATE;
|
|
|
|
const sdk = await SandboxAgent.start({
|
|
sandbox: e2b({
|
|
template,
|
|
create: { envs },
|
|
}),
|
|
});
|
|
|
|
try {
|
|
const session = await sdk.createSession({ agent: "claude" });
|
|
const response = await session.prompt([
|
|
{ type: "text", text: "Summarize this repository" },
|
|
]);
|
|
console.log(response.stopReason);
|
|
} finally {
|
|
await sdk.destroySandbox();
|
|
}
|
|
```
|
|
|
|
The `e2b` provider handles sandbox creation, Sandbox Agent installation, agent setup, and server startup automatically. Sandboxes pause by default instead of being deleted, and reconnecting with the same `sandboxId` resumes them automatically.
|
|
|
|
Pass `template` when you want to start from a custom E2B template alias or template ID. E2B base-image selection happens when you build the template, then `sandbox-agent/e2b` uses that template at sandbox creation time.
|
|
|
|
## Faster cold starts
|
|
|
|
For faster startup, create a custom E2B template with Sandbox Agent and target agents pre-installed.
|
|
Build System 2.0 also lets you choose the template's base image in code.

See [E2B Custom Templates](https://e2b.dev/docs/sandbox-template) and [E2B Base Images](https://e2b.dev/docs/template/base-image).
