Twilio SMS

SMS MCP Server enables Claude and other AI assistants to send SMS and MMS messages through Twilio's API. Built by Yiyang Li, this TypeScript implementation provides a simple interface for sending text messages with proper phone number validation and error handling. The server exposes both a general-purpose message sending tool and specialized prompts for sending greetings and haikus, making it particularly useful for applications where AI assistants need to communicate with users via text messaging without leaving the conversation interface.
