create_payment_link

Create a payment link in SGD for Singapore via HitPay. Buyer pays with PayNow QR (the rail Singapore actually uses), cards, and other methods enabled on the HitPay account. Returns a hosted checkout URL the buyer opens to pay — payment completes automatically, no confirm step. Bring your own credentials via HTTP header (x-hitpay-api-key; free test credentials from dashboard.hit-pay.com never move real money). Money always flows buyer→HitPay→merchant; this service never touches funds.

Parameters4

amount_sgd	number	required	Amount in SGD (decimals allowed), e.g. 10. Minimum 1.
description	string	required	What this payment is for (shown to the buyer, ≤200 chars)
customer_email	string	optional	Optional buyer email.
success_url	string	optional	Optional https URL to send the buyer to after payment.

Singapore Payments MCP — let AI agents accept payments in Singapore

Use it in 60 seconds

Paste this into your MCP client config (Claude Desktop, Cursor, Windsurf, or any MCP-capable agent):

json

{
  "mcpServers": {
    "singapore-payments": {
      "type": "http",
      "url": "https://mcp-sg.wishpool.app/mcp"
    }
  }
}

Nothing to install. Credentials, when you need them, travel as HTTP headers on each request and are never stored — see the threat model.

Or run it yourself

Would you rather not send production credentials to a server you do not control? Deploy this identical code to your own account and point your agent at your own URL:

bash

git clone https://github.com/junter1989k-ai/singapore-payments-mcp && cd singapore-payments-mcp && npx vercel --prod
