## Description

The WhatsApp MCP server enables AI assistants to send WhatsApp messages through Twilio's API. Built with FastMCP, this implementation loads Twilio credentials from environment variables, establishes a secure connection to the Twilio service, and exposes a single tool for sending formatted WhatsApp messages to specified recipients. The server handles proper E.164 number formatting, provides detailed error reporting, and can be called either through a standalone script or integrated into larger applications. It's particularly valuable for automated notification systems, customer service workflows, and any scenario where AI assistants need to communicate with users via WhatsApp without switching contexts.
