# Vercel AI SDK

> Use Mandate with the Vercel AI SDK to enforce spending policies on AI-generated transactions.

<Info>
  **Coming soon.** A dedicated Vercel AI SDK plugin with tool-level interception is in development. In the meantime, use the Mandate TypeScript SDK directly alongside the Vercel AI SDK.
</Info>

## Using Mandate with Vercel AI SDK today

Mandate works with any AI framework through the TypeScript SDK. Call `MandateClient.validate()` before any tool that sends a transaction.

```typescript theme={null}
import { MandateClient, PolicyBlockedError } from '@mandate.md/sdk';
import { generateText } from 'ai';

const mandateClient = new MandateClient({
  runtimeKey: process.env.MANDATE_RUNTIME_KEY!,
});

// Before executing any transaction tool:
try {
  const result = await mandateClient.validate({
    action: 'transfer',
    amount: '50',
    to: '0xRecipientAddress',
    token: 'USDC',
    reason: 'AI-generated payment for data analysis',
  });
  console.log('Allowed. IntentId:', result.intentId);
} catch (err) {
  if (err instanceof PolicyBlockedError) {
    console.log('Blocked:', err.blockReason);
  }
}
```

Add this validation check inside any tool definition that triggers on-chain actions. The `validate()` call takes less than 200ms and runs your transaction against all 14 policy checks.

## What the dedicated plugin will add

The planned Vercel AI plugin will intercept tool calls automatically, so you do not need to add manual `validate()` calls. It will wrap your tool definitions and enforce Mandate policies at the framework level before execution.
