Enables sending SMS messages through Twilio's messaging service, with support for configurable recipients and default phone numbers.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Twilio MCP send a text to my friend saying I'll be 10 minutes late"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Simple MCP server for sending SMS via Twilio. Pure TypeScript, no build step.
