Vercel

Prerequisites

• VERCEL_OIDC_TOKEN or VERCEL_ACCESS_TOKEN
• ANTHROPIC_API_KEY or OPENAI_API_KEY

TypeScript example

npm install [email protected] @vercel/sandbox

import { SandboxAgent } from "sandbox-agent";
import { vercel } from "sandbox-agent/vercel";

const env: Record<string, string> = {};
if (process.env.ANTHROPIC_API_KEY) env.ANTHROPIC_API_KEY = process.env.ANTHROPIC_API_KEY;
if (process.env.OPENAI_API_KEY) env.OPENAI_API_KEY = process.env.OPENAI_API_KEY;

const sdk = await SandboxAgent.start({
  sandbox: vercel({
    create: {
      runtime: "node24",
      env,
    },
  }),
});

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 vercel provider handles sandbox creation, Sandbox Agent installation, agent setup, and server startup automatically.

Authentication

Vercel Sandboxes support OIDC token auth (recommended) and access-token auth. See Vercel Sandbox docs.
