How to Use the Adyen MCP in Mastra AI

Q: How do I handle Adyen refund failures in Mastra AI workflows?

You map the refundpayment tool inside a Mastra step. If the tool returns an error, Mastra's built-in retry engine will automatically attempt the refund again based on your backoff rules.

Q: Can Mastra AI automatically audit my Adyen merchant accounts?

Yes. You can build a workflow that calls listmerchants to get all account IDs, then runs getmerchantdetails on each to verify configuration status.

Q: How do I require human approval for Adyen refunds in Mastra AI?

You configure requireToolApproval on the refundpayment tool inside Mastra's MCP client. Mastra will pause the workflow and wait for an admin's thumbs-up before sending the refund request to Adyen.

Q: Does Mastra support the 16-digit PSP reference format?

Yes. The agent validates that the input for getpaymentdetails or refundpayment is a valid 16-digit string before executing the workflow step.

Mastra AI Self-Healing Adyen Refunds

When an automated refund fails, you don't want your system to just crash. Mastra AI can execute `refund_payment` and, if the Adyen gateway returns an error, use its built-in workflow engine to retry with exponential backoff. If the refund still fails after three attempts, the workflow branches to notify an admin. Your agent manages the entire loop using the 16-digit PSP reference without manual intervention.

Multi-Region Adyen Merchant Audits

Running routine checks across global accounts is simple with Mastra AI agents using this MCP Server. The agent runs `list_merchants` to scan all active accounts, then loops through each ID using `get_merchant_details` to check for configuration drift. This setup runs as a scheduled background workflow. It ensures your US and EU merchant configurations stay identical without you having to write custom cron jobs.

Conditional Adyen Payment Analysis

You can build complex decision trees based on transactional data. This MCP Server lets your Mastra agent fetch details via `get_payment_details` and run conditional branching based on whether the payment was captured or authorized. If the payment metadata flags a high-risk score, your workflow can automatically pause and require human approval before proceeding.

Setup guide

Set up Adyen 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 Adyen 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: "adyen-mcp-client",
  servers: {
    "adyen-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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