Vercel Sandbox

The Vercel Sandbox connector adapts an initialized @vercel/sandbox Sandbox into Flue’s sandbox interface. Use it when application code should execute agent work inside a Vercel-managed sandbox rather than on its host filesystem.

Add the connector

pnpm exec flue add vercel

Requirements

Requirement	Value
Provider package	@vercel/sandbox
Authentication	VERCEL_OIDC_TOKEN or the authentication flow appropriate to your Vercel environment
Integration shape	Application creates a sandbox, then passes it through the generated connector
Lifecycle ownership	Your application decides retention and cleanup

Typical use

import { Sandbox } from '@vercel/sandbox';
import { createAgent } from '@flue/runtime';
import { vercel } from '../connectors/vercel';

const sandbox = await Sandbox.create({ runtime: 'node24' });
const agent = createAgent(() => ({
  model: 'anthropic/claude-sonnet-4-6',
  sandbox: vercel(sandbox),
}));

Keep Vercel authentication values in trusted application configuration and determine whether sandboxes should be fresh per job or reusable for stable agent identities.
