Stripe

This wraps Stripe's payment API so Claude can manage customers, products, subscriptions, invoices, and payouts without you handling auth tokens. It runs through Membrane's CLI, which means you authenticate once and the platform handles credential refresh automatically. You get pre-built actions for common operations like listing products or creating prices, plus a proxy for direct API calls when you need something specific. The connection setup can require a few polling steps if the connector needs to build, but once it's ready you're just running commands. Makes sense if you're already using Membrane or want to avoid storing Stripe keys locally. Free tier works fine.
