Twilio MCP: Control SMS, Voice, and Messaging from Your AI Agent

The Twilio MCP server is the official integration that lets Claude, Cursor, and other AI agents send SMS, MMS, WhatsApp messages, and place voice calls—all through natural language prompts. No more building custom API wrappers. Your agent gets direct, secure access to Twilio's programmable communications platform.

What It Does

Twilio MCP unlocks a full suite of communication capabilities for AI workflows. You can send and receive SMS and MMS, trigger WhatsApp messages, place and manage voice calls, and access chat sessions through Twilio Conversations. The server also lets you inspect message logs, check delivery status, manage phone numbers, and query usage metrics—all without exposing API keys in your prompts.

This is especially useful for notification systems, OTP flows, customer outreach, and automated reminders. Instead of writing boilerplate code to hit Twilio's REST API repeatedly, you describe what you want your agent to do in English, and it handles the plumbing. The server enforces secure credential handling, keeping your Twilio account tokens isolated from your AI prompts.

How to Install

npx -y @twilio/mcp

Add the server to your Claude Desktop config:

{
  "mcpServers": {
    "twilio-mcp": {
      "command": "npx -y @twilio/mcp",
      "env": {
        "TWILIO_ACCOUNT_SID": "your-account-sid",
        "TWILIO_AUTH_TOKEN": "your-auth-token"
      }
    }
  }
}

Grab your credentials from the Twilio Console, set them as environment variables, and restart Claude Desktop.

Real-World Use Cases

• Two-Factor Authentication Flows: Ask Claude to verify a user's phone number by generating a one-time code and sending it via SMS—all in one agent interaction.
• Customer Notification Dashboards: Let an agent monitor your system and auto-send alerts to stakeholders via SMS or WhatsApp based on predefined triggers.
• Bulk Outreach Campaigns: Compose a batch of personalized messages in Claude, have the agent send them through Twilio, and track delivery status programmatically.
