Perplexity

Generate payment-ready code using the MCP Server.

Need to write a checkout function? Let the AI use `init_secure_payment` and inject the live session data directly into your current file. The generated code calls real API responses, not stubs. This makes building secure e-commerce logic fast; you just need to define the parameters for the payment initiation.

Securely handle card tokenization in Cursor.

Instead of hardcoding sensitive details, use `request_card_token`. The AI generates code that calls this function first, giving you a safe, usable token. This is essential for any production-grade payment system. If the user cancels their account, simply call `cancel_card_token` and integrate that cleanup logic into your codebase.

Build robust KYC verification steps in Cursor.

Integrate identity checks by having the AI invoke `verify_card_kyc`. This ensures the code path only proceeds if the user's credentials are fully verified. Furthermore, always check the risk status using `check_card_risk_status` before that KYC step. It adds a necessary layer of defense to your payment logic.

Setup guide

Set up UnionPay Open Platform MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the UnionPay Open Platform MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent UnionPay Open Platform transactions." If the MCP tools are loaded correctly, Cursor will call the UnionPay Open Platform tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "unionpay-open-platform-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"

Common questions about UnionPay Open Platform MCP in Cursor

You enable Agent mode in the chat, which allows the AI to recognize that it needs external data. It then calls tools like `get_qr_transaction_status` and injects the resulting JSON into the code you're writing.

The primary data types involved are card tokens, transaction statuses (for QR codes), and KYC identity records. The AI needs to handle these structured outputs accurately in your code.

Yes. You can write the entire sequence: `init_secure_payment` -> check risk status -> generate QR code -> confirm status, all while letting the AI fill in the working API calls.

You must use it whenever you need to save a user's payment method for later. Running `request_card_token` is the correct pattern here.

Yes. The server touches card tokens and KYC identity records. By generating code that handles these inputs, you ensure sensitive data flows are managed through defined functions like `verify_card_kyc`.
