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):

{
  "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:

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

A remote MCP server that lets any AI agent (Claude, ChatGPT, Cursor…) accept payments in Singapore: PayNow QR (the rail Singapore actually uses), cards, and other methods enabled on the HitPay account — via HitPay's hosted checkout.

⚖️ Stateless translation layer: funds always flow buyer → HitPay → merchant directly. Never holds funds or stores credentials — no database at all.

Quick start

MCP endpoint: https://mcp-sg.wishpool.app/mcp (Streamable HTTP, stateless JSON-RPC)

Header	Value
`x-hitpay-api-key`	your HitPay business API key (sandbox keys from api.sandbox.hit-pay.com dashboard — also send x-hitpay-mode: sandbox; default production)

Tools

Tool	What it does
`create_payment_link`	Create a SGD hosted-checkout link.
`query_payment_status`	Pull-based status check; `paid=true` when PAID.

Develop

node test/serve.js      # local server (http://localhost:3229/mcp)
node test/e2e.js        # protocol + validation suite (probes real HitPay auth errors)
