What is the Klarna MCP Server?
Connect your Klarna merchant account to any AI agent to automate your e-commerce payment and order management workflows. This MCP server enables your agent to interact with both the Klarna Payments API (checkout phase) and the Order Management API (post-purchase phase) directly from natural language.
What you can do
- Session Control — Create and manage checkout sessions to obtain client tokens for your frontend
- Order Placement — Formally place orders using authorization tokens from your checkout widget
- Payment Ingestion — Capture authorized orders to trigger the actual payment from the customer
- Financial Resolution — Process full or partial refunds and cancel authorized but uncaptured orders
- Logistics Integration — Update shipping information and tracking numbers for existing orders
- Data Oversight — Retrieve detailed status, financial totals, and metadata for any Klarna order
How it works
- Subscribe to this server
- Enter your Klarna API Key (Username), Shared Secret, and Region Domain
- Start managing your payments and orders from Claude, Cursor, or any MCP-compatible client
Who is this for?
- E-commerce Operations — Monitor order statuses and process captures/refunds via simple natural language commands
- Financial Controllers — Quickly audit payment sessions and transaction totals without logging into the portal
- Developers — Integrate Klarna's complex two-phase payment logic and status monitoring into your custom applications

Frequently asked questions
How do I determine my Klarna Region Domain?
Use api.klarna.com for Europe, api-na.klarna.com for North America, or api.playground.klarna.com for testing/sandbox environments.
What is the difference between authorizing and capturing an order?
Authorizing only reserves the funds. You must use the capture_klarna_order tool (typically when shipping) to actually move the money from the customer to your account.
Can I process partial refunds?
Yes, the refund_klarna_order tool accepts a JSON object where you can specify the exact amount and the specific items being refunded.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
