You can deploy your own Twilio MCP server with Serverless Functions. To get started, you'll need a Twilio account, the Twilio CLI installed on your machine, and an OpenAI API Key. You can then fetch the Twilio MCP server code, initialize it locally, set environment variables, start the server locally, connect to it using the MCP Inspector, deploy the server to Twilio Functions, and use it with the OpenAI Responses API to purchase a phone number and send an SMS. The Twilio Serverless Toolkit can handle deploying your functions for you. You'll receive a URL for your MCP server that is hosted on Twilio's serverless Functions. With this setup, you can view the logs of your server in real-time using Live Log Tailing with the toolkit or in the Console Functions UI. Next steps include adding other services with prompts and exploring more samples in the openai-mcp-samples repository.
