This connects Claude to Big Cartel's e-commerce API through Membrane's authentication layer, so you can manage products, orders, categories, and discounts without handling OAuth yourself. Built for artists and creators selling online. You get 20+ pre-built actions covering the usual CRUD operations, plus a proxy for direct API calls when you need something custom. The Membrane CLI handles credential refresh automatically, which is nice if you're building longer-running automations. Best for storefronts with inventory management needs rather than one-off queries. Free tier works fine for most use cases.
