MCP Samples

This repo contains sample code for using OpenAI's Responses API and MCP server.

Pre-requisites

Before you start, make sure you already have deployed Twilio MCP Server to your account. For more information, see Twilio MCP Function Templates.

Usage

This code sample is using OpenAI's Response API and support for remote MCP server.

1. Copy .env.sample to .env
2. Replace your Twilio AUTH_TOKEN and generate a new OPENAI_API_KEY
3. Copy the Twilio Function domain that is hosting your Twilio MCP server
4. Make any changes you want to the index.js prompt and run npm start

Security Recommandations

This MCP server function will provide Tools to your LLM that provide access to your Twilio account. We recommend the following considerations when giving clients access to your server:

• Always set your MCP client to require tool approval to ensure that there are no unintended actions taken within your account.
• Use scoped permissions for your Twilio API Key. Not all endpoints support scoped permissions, but some do. See https://www.twilio.com/docs/iam/api-keys/restricted-api-keys for more information about which actions are supported per API Service.
• To ensure privacy, do not use other MCP servers in conjunction with your Twilio MCP server.
