How to Use the Klarna MCP in Cursor

Q: How do I test a payment flow using Klarna in Cursor?

Open Cursor Agent mode and ask it to run createpaymentsession with your test cart details. The agent initiates the session and provides the token for your frontend test.

Q: Can Cursor help me capture an authorized Klarna order?

Yes, you can command the Cursor agent to execute captureklarnaorder with the target order ID. This instantly captures the funds and updates the order state in your test environment.

Q: How do I verify Klarna order details during development in Cursor?

Ask Cursor to run getorderdetails for any active transaction. The editor displays the full JSON payload, including line items and billing addresses, right next to your code.

Q: What tool updates shipping references?

Use updateordershipping to modify the merchant references on the gateway. This ensures your local fulfillment scripts match the remote transaction details.

Generate checkout code with live Cursor context

The `create_payment_session` tool pulls real session data into your Cursor editor via this MCP Server to help you write accurate frontend integration code. Instead of guessing the JSON structure of a session response, your editor gets the live Klarna payload directly from the gateway. You write your React or Vue checkout components while Cursor uses `get_payment_session` to verify that your UI components map correctly to active Klarna session properties. This eliminates Klarna mock data mismatch bugs before you commit your Cursor code.

Test order captures with this MCP Server

The `create_klarna_order` tool converts an authorized session token into a formal transaction right from your Cursor coding interface. Your Cursor agent runs this tool to simulate successful Klarna checkouts and verify your database write-backs. Once the order is created, you use `capture_klarna_order` in Cursor to test your fulfillment webhook handlers under realistic conditions. You watch your local server logs respond to the Klarna capture event as the Cursor agent triggers it.

Debug refund flows and shipping updates

The `refund_klarna_order` tool lets you debug your payment return logic by executing live test refunds directly from the Cursor editor sidebar. Cursor feeds the resulting Klarna payload into your unit tests to verify that your database registers the correct negative balance. If you need to test address corrections, `update_order_shipping` updates the merchant reference on the Klarna order. You then call `get_order_details` in Cursor via the MCP integration to verify that your local shipping service syncs perfectly with the gateway's state.

Setup guide

Set up Klarna 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 Klarna 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 Klarna transactions." If the MCP tools are loaded correctly, Cursor will call the Klarna tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

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