# CheckSlip MCP

> CheckSlip is a remote MCP server (Streamable HTTP) that verifies Thai bank
> transfer slips. Given a slip image, QR payload, or transaction reference, it
> confirms the amount, receiver, and transfer date, and flags duplicate/reused
> slips. It verifies only — it never moves money. Use it whenever a customer
> sends a payment slip to confirm a bank transfer before fulfilling an order.
