A Model Context Protocol (MCP) server that enables Claude and other AI assistants to send SMS and MMS messages using Twilio.
Twilio sms mcp mcp server lets Claude, Cursor and other MCP clients work with Twilio Sms MCP directly. A Model Context Protocol (MCP) server that enables Claude and other AI assistants to send SMS and MMS messages using Twilio.
A versatile SMS service that can run as both a Model Context Protocol (MCP) server for Claude Desktop and as a standalone REST API for cloud deployment.
Setup follows the standard MCP pattern: clone or install the server, then register it in your client's configuration file and restart the client. The configuration snippets on this page cover Claude Desktop, Claude Code and Cursor.
Before the server will start you need to supply 3 environment variables: ACCOUNT_SID, AUTH_TOKEN, FROM_NUMBER. Keep credentials in your client's env block or a secrets manager rather than committing them.
Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Twilio Sms MCP sits in that group. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
