How to Use the UnionPay Open Platform MCP in Mastra AI

The verifycardkyc tool manages identity and card binding information. The agent framework treats this verification as a critical step in the overall payment workflow.

Perplexity

Complex Payment Retries via Mastra AI

Build multi-step processes that handle failures gracefully. If a payment attempt fails, your agent framework can automatically retry the transaction using `init_secure_payment` or switch methods. This resilience is built-in: it uses exponential backoff and conditional branching to keep workflows running even when things go wrong.

Card Lifecycle Management with Mastra AI

The framework manages the entire card lifecycle. You can use `request_card_token` for initial secure storage, and later call `cancel_card_token` if a customer changes their account details. This structured approach ensures your payment system stays accurate over time.

Multi-Step Payment Verification with Mastra AI

You can sequence multiple checks into one robust workflow. For example, first calling `verify_card_kyc`, then checking the risk status using `check_card_risk_status` before authorizing a payment. This guarantees all necessary preconditions are met before proceeding to checkout.

Setup guide

Set up UnionPay Open Platform MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All UnionPay Open Platform tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "unionpay-open-platform-mcp-client",
  servers: {
    "unionpay-open-platform-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "UnionPay Open Platform Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to UnionPay Open Platform tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent UnionPay Open Platform transactions"
);
console.log(result.text);
