WhatsApp MCP Server connects a personal WhatsApp account to Claude Desktop (and Cursor) through the Model Context Protocol, using a two-component architecture: a Go bridge built on the whatsmeow library that authenticates via QR code scan and stores message history locally in SQLite, and a Python MCP server that exposes twelve tools to Claude. Those tools cover reading and searching messages across individual and group chats, retrieving contact information, and sending text, images, videos, documents, and audio files. Audio messages have a notable detail: the server automatically converts non-Opus audio to the required .ogg format when FFmpeg is installed, enabling proper WhatsApp voice message playback. All message data remains in a local SQLite database and is only forwarded to Claude when a tool call explicitly requests it. The project targets individuals who want to interact with their personal WhatsApp history and contacts through Claude's conversational interface. The README includes a prompt injection warning relevant to any MCP server that handles private message data.
