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.

​
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. 
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.
