This lets Claude send WhatsApp messages, manage contacts, and interact with chats through the Membrane platform. You get all the standard messaging actions like sending text, images, documents, videos, plus interactive buttons and list menus. It also handles business profile operations and message reactions. The Membrane CLI takes care of authentication and credential refresh, so you're not wrestling with OAuth flows or token expiration. Worth noting this requires a Membrane account, though the free tier works. If you're building anything that needs to programmatically send WhatsApp messages or read chat data, this covers the essentials without manually calling Meta's API.
