Summary
This connects Claude to WhatsApp via a QR code scan, no official API required. You get tools to send text messages, images, links, and locations through WhatsApp Web's multi-device protocol. Built in Go for efficient memory use, it runs as either a REST service or MCP server. The underlying implementation supports auto-replies, webhooks for incoming messages, and bulk operations. Useful when you need to build WhatsApp automation or notification flows without dealing with Meta's Business API approval process. It also handles media compression and can mark messages as read automatically. The project includes ARM and AMD builds plus Docker images if you want to self-host.
