Perplexity

Automate payment captures with Mastra AI

Authorized charges drop off if you wait too long. You can build a workflow that runs `capture_checkout_payment` on a strict schedule before the authorization window expires. The MCP Server handles the remote execution while the framework's exponential backoff kicks in during network drops. Your code retries the operation automatically without manual intervention.

Handle refund logic with conditional branches

Returns require careful checks before moving money. Your agent can call `get_payment_details` to verify the original charge status before deciding what to do next. Based on the result, the workflow branches. It either triggers `refund_checkout_payment` for settled transactions or executes `void_checkout_payment` if the charge is still pending.

Track lifecycle events reliably

Complex integrations break when webhooks fail. You can pull the exact sequence of events using `list_payment_actions` to debug transaction states directly from your MCP Server connection. Spread the results from mcpClient.listTools() into your agent configuration. You can even enforce requireToolApproval so a human manager signs off on large refunds.

Setup guide

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

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

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