About 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.
The Vercel AI SDK gives every Klarna tool full TypeScript type inference, IDE autocomplete, and compile-time error checking. Connect 8 tools through the Vinkius and stream results progressively to React, Svelte, or Vue components — works on Edge Functions, Cloudflare Workers, and any Node.js runtime.
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
