Automate Payments using the UnionPay Open Platform MCP Server

You can start a checkout session for secure payments by calling `init_secure_payment`. This tool handles the online payment setup, making it easy to complete transactions inside Windsurf. If you need to generate a QR code for in-person payments, just run `generate_qr_code`. The agent figures out the steps and executes both the secure initialization and the QR generation automatically.

Manage Card Tokens via MCP Server

Need to save card details for later? Use `request_card_token` to tokenize a UnionPay card. This keeps your payment system secure while allowing future purchases. When you're done with a token, or if the user cancels, call `cancel_card_token`. That removes the binding and cleans up the record.

Verify Identities and Check Status

Before processing anything, verify the card owner using `verify_card_kyc`. This checks both the identity and the card's official binding to an account. Furthermore, you can check the risk status of a card with `check_card_risk_status`, or confirm if a payment attempt succeeded by checking the transaction status via `get_qr_transaction_status`.
