WhatsApp MCP Server provides a secure bridge to your personal WhatsApp account, enabling AI assistants to search messages, manage contacts, and send messages through standardized tools. The implementation uses a two-component architecture with a Go-based WhatsApp bridge that connects to the WhatsApp web API via the whatsmeow library, storing all messages locally in SQLite, and a Python MCP server that exposes functionality through nine specialized tools. Designed for privacy, it keeps your message history on your device while allowing controlled AI access to your conversations for tasks like finding past information or sending new messages.
