The Paddle plugin connects Claude Code to Paddle Billing, a merchant of record for SaaS, AI, mobile app, and digital product businesses. It provides step-by-step guidance for the most common Paddle integration tasks and wires up the Paddle docs MCP server so Claude pulls from up-to-date documentation as it works — helping you follow Paddle's recommended patterns for checkout, subscriptions, and webhooks instead of guessing from stale examples.
