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.
Mastra's agent abstraction provides a clean separation between LLM logic and Klarna tool infrastructure. Connect 8 tools through the Vinkius and use Mastra's built-in workflow engine to chain tool calls with conditional logic, retries, and parallel execution — deployable to any Node.js host in one command.
