Your agent is about to pay a supplier. Should it?

{
  "mcpServers": {
    "jid": {
      "type": "http",
      "url": "https://jid.com/mcp",
      "headers": {
        "Authorization": "Bearer ${JID_KEY}"
      }
    }
  }
}

Before paying any supplier, call verify_business with the supplier, the activity you are paying for and the amount.
Pay only if decision is "proceed", and record receipt_id with the payment.
If decision is "review" or "insufficient_data", show me the reasons that are not met and ask before paying.
If decision is "stop", do not pay.

// Before the agent pays a supplier: verify, act on the decision, keep the receipt.
const JID = "https://jid.com/v1";
const headers = { Authorization: `Bearer ${process.env.JID_KEY}` };

type Decision = "proceed" | "review" | "stop" | "insufficient_data";

export async function checkSupplier(supplier: string, activity: string, amountUsd: number) {
  // 1. Resolve the supplier by name or registry number (FEI, LEI, CIK, USDOT...). Search is free.
  const s = await fetch(`${JID}/search?q=${encodeURIComponent(supplier)}`, { headers }).then((r) => r.json());
  const file = s.results?.[0];
  if (!file) return { decision: "insufficient_data" as Decision, reasons: [], receiptId: null };

  // 2. One check: the decision for this activity, with reasons and a signed receipt.
  const url = `${JID}/entities/${file.id}/verify?activity=${activity}&amount=${amountUsd}&currency=USD`;
  const v = await fetch(url, { headers }).then((r) => r.json());
  return {
    decision: v.decision.decision as Decision,
    reasons: v.decision.reasons.filter((r: any) => r.met !== true), // what blocks or needs a person
    receiptId: v.receipt.receipt_id as string,                       // store with the purchase order
  };
}

// In the payment tool:
const c = await checkSupplier("Gland Pharma", "sell_prescription_drugs", 37000);
if (c.decision === "proceed") {
  // pay, and record c.receiptId on the payment
} else if (c.decision === "stop") {
  // do not pay; tell the user why (c.reasons)
} else {
  // review or insufficient_data: show c.reasons and ask the user before paying
