Perplexity

Automated order flow control

Build complex sequences using `create_klarna_order` and `capture_klarna_order` within your agent workflows. If a payment fails, your agent can catch the error and trigger a retry path. This removes manual intervention from your checkout process. You define the logic, and the server executes the steps to ensure every order reaches the capture stage.

Resilient shipping updates

Use `update_order_shipping` to keep your fulfillment data in sync with your logistics provider. The agent checks the order status via `get_order_details` before applying any updates. This prevents conflicts during the shipping phase. If an update fails, your workflow can log the error and notify your team for manual review.

Safe transaction reversals

Manage cancellations and refunds through `cancel_authorized_order` and `refund_klarna_order` tools. Your agent performs these operations based on your defined business rules. This protects your revenue by ensuring reversals only occur when specific conditions are met. You maintain complete oversight of the entire post-purchase process.

Setup guide

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

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

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

Common questions about Klarna MCP in Mastra AI

You can configure your agent workflow to watch for specific error codes returned by the tools. If a failure occurs, the agent automatically triggers the next step in your sequence.

Yes. Each agent maintains its own context, allowing you to manage several sessions or orders concurrently without data collision.

The framework uses shared memory to track order IDs and session tokens across different agent turns. This keeps your workflow state consistent throughout the transaction.

Enable the approval requirement in your agent settings. This forces the agent to pause and ask for confirmation before executing sensitive tools like refunds.

The server retrieves order-specific metadata like shipping addresses and line items. It does not access private financial data, and all logs are isolated within your secure environment.
