OFAC Screens Before AgentKit Agents Send Payments

The problem

Coinbase AgentKit agents can interact with any on-chain address. The agent does not know if the destination wallet belongs to a sanctioned entity. OFAC liability does not disappear because a smart contract sent the transaction.

Code example

import { Agentkit } from "@coinbase/agentkit";
  import { AgentMailMCP } from "@agentmail/mcp";

  const ofac = new AgentMailMCP({
    mode: "mcp",
    apiKey: "am_your_key"
  });

  // Before your agent sends:
  const screen = await ofac.screenWallet({
    address: "0x742d35Cc6634C0532929dC57EB0615e2383E2f96",
    chain: "ethereum"
  });
  if (screen.flagged) throw new Error("Blocked by sanctions");
