Description

WhatsApp Web MCP is a Node.js application that bridges WhatsApp Web with AI models using the Model Context Protocol, enabling programmatic message sending, contact and group management, media handling, and webhooks. It can run as a standalone MCP server, a WhatsApp REST API server, or an MCP client that talks to a local API server, providing flexible deployment modes (SSE or command). The project uses whatsapp-web.js under the hood and includes logging, authentication strategies, and integration examples (e.g., Claude Desktop). It is intended for testing and automation scenarios and explicitly notes it is not affiliated with WhatsApp.
