OFAC Screens Before AI SDK Agents Pay

The problem

Agents built with the Vercel AI SDK can use tool calling to initiate payments. Without a sanctions tool in the loop, the agent has no way to know if a wallet address is on the OFAC SDN list. The deployment operator bears strict liability.

Code example

import { generateText } from "ai";
import { sanctionsCheck } from "@agentmail/mcp-sdk";
import { openai } from "@ai-sdk/openai";

const result = await generateText({
  model: openai("gpt-4o"),
  tools: {
  sanctionsCheck,
  sendPayment: {
    description: "Send USDC to wallet",
    parameters: ...,
    execute: async ({ wallet }) => {
    // Always screen before payment
    const screen = await sanctionsCheck({ wallet });
    if (screen.flagged) throw new Error("Blocked by OFAC");
    return executePayment(wallet);
    }
  }
  },
  prompt: "Pay the invoice from wallet 0x..."
});
