Recursive Proxy

wrap() intercepts every method call no matter how deeply nested, preserving your original TypeScript types completely.

Approval Gates

Pass requiresApproval to wrap() to pause execution until a human reviewer approves from the dashboard.

Automatic Rollback

If a reviewer rejects or any action fails, AgentRein reverses every previous action in LIFO order automatically.

​
The Recursive Proxy

The core of AgentRein SDK’s power comes from the wrap() method. Rather than forcing you to learn a new syntax, wrap() uses a Recursive JavaScript Proxy to intercept your existing client’s actions. When you call agentrein.wrap(client, session, { connector }), it intercepts every method call, no matter how deeply nested (e.g., octokit.rest.issues.create). It tracks the action, logs it to the backend, executes the original function, and registers it for potential rollback — while completely preserving your original TypeScript types.

​
Approval Gates

For high-risk methods that need human sign-off, pass requiresApproval directly to wrap():
Methods not listed in requiresApproval execute immediately without interruption. Only listed paths trigger the approval gate.
const agentStripe = agentrein.wrap(stripe, session, {
    connector: 'stripe',
    requiresApproval: ['subscriptions.cancel', 'invoices.del'],
});

// Normal methods execute immediately
await agentStripe.invoices.create({ customer: 'cus_123' });

// Methods in requiresApproval pause until a reviewer approves
await agentStripe.subscriptions.cancel({ id: 'sub_123' });
If a reviewer rejects the action, ApprovalRejectedError is thrown and the session is automatically rolled back.
