Twilio Manager MCP

A Model Context Protocol (MCP) implementation for managing Twilio resources. This package provides tools for managing Twilio subaccounts, phone numbers, and regulatory bundles through a standardized MCP interface.

Features

• List Twilio subaccounts
• Get phone numbers associated with subaccounts
• Transfer phone numbers between subaccounts
• Get regulatory bundle SIDs
• Support for both direct and Server-Sent Events (SSE) communication
• Integration with Claude Desktop, Cursor, and other MCP-compatible tools

Installation

Prerequisites

Install uv

On macOS:

brew install uv

On Windows:

powershell -c "irm https://astral.sh/uv/install.ps1 | iex"

On Linux:

curl -LsSf https://astral.sh/uv/install.sh | sh

Project Setup

1. Clone the repository:

git clone https://github.com/yourusername/twilio_manager_mcp.git
cd twilio_manager_mcp

2. Install dependencies using uv:

uv sync

Configuration

1. Create a .env file in the root directory with your Twilio credentials:

TWILIO_ACCOUNT_SID=your_account_sid
TWILIO_AUTH_TOKEN=your_auth_token

2. Configure MCP for your tool (Cursor, Claude Desktop, etc.) by creating a .cursor/mcp.json file:

{
  "mcpServers": { 
    "twilio_manager_mcp_abs": {
      "command": "uv",
      "args": ["--directory", "/path/to/twilio_manager_mcp", "run", "mcp", "run", "./twilio_manager_mcp.py"],
      "env": {
        "TWILIO_ACCOUNT_SID": "your_account_sid",
        "TWILIO_AUTH_TOKEN": "your_auth_token"
      }
    },
    "twilio_manager_mcp_uvx": {
      "command": "uvx",
      "args": [ "twilio-manager-mcp" ],
      "env": {
        "TWILIO_ACCOUNT_SID": "your_account_sid",
        "TWILIO_AUTH_TOKEN": "your_auth_token"
      }
    },
    "twilio_manager_mcp_sse": {
      "url": "http://localhost:8000/sse"
    }
  }
}

Docker

You can run Twilio Manager MCP using Docker for easier deployment and management.

Using Docker Compose

The project includes a Docker Compose configuration that sets up:

• The Twilio Manager MCP service
• A Traefik reverse proxy with automatic HTTPS

1. Configure environment variables in your .env file:

# Twilio credentials
TWILIO_ACCOUNT_SID=your_account_sid
TWILIO_AUTH_TOKEN=your_auth_token

# Domain configuration for Traefik
DOMAIN_NAME=yourdomain.com
ACME_EMAIL=user@yourdomain.com

# Address details (optional)
ADDRESS_CUSTOMER_NAME=
ADDRESS_FRIENDLY_NAME=
ADDRESS_STREET=
ADDRESS_CITY=
ADDRESS_REGION=
ADDRESS_POSTAL_CODE=
ADDRESS_ISO_COUNTRY=

2. Start the services:

docker-compose up -d

The application will be available at your configured domain with HTTPS enabled.

Using Docker Without Docker Compose

If you prefer to run just the Twilio Manager MCP container without Traefik:

1. Build the Docker image:

docker build -t twilio-manager-mcp .

2. Run the container:

docker run -p 8000:8000 \
  -e TWILIO_ACCOUNT_SID=your_account_sid \
  -e TWILIO_AUTH_TOKEN=your_auth_token \
  twilio-manager-mcp

The SSE endpoint will be available at http://localhost:8000/sse.

Usage

With Cursor, Claude Desktop, or other MCP-compatible tools

You have three options to use this MCP:

1. Direct UVX Integration (Recommended):

   • Use the twilio_manager_mcp_uvx configuration
   • This is the simplest method and works out of the box with uvx

2. Direct UV Integration:

   • Use the twilio_manager_mcp_abs configuration
   • Requires specifying the full path to your installation

3. SSE Server:

   • Use the twilio_manager_mcp_sse configuration
   • Start the SSE server first:

     uvicorn twilio_manager_mcp_sse:app --host 0.0.0.0 --port 8000
     

Available Tools

Tool Name	Description
list_twilio_subaccounts	List all Twilio subaccounts
get_account_phone_numbers	Get phone numbers for a specific subaccount
get_all_phone_numbers	Transfer phone numbers between subaccounts
get_regulatory_bundle_sid	Get regulatory bundle SID for a subaccount

Example Usage in Cursor/Claude Desktop

Once configured, you can use the tools directly in your AI assistant conversations:

1. List all subaccounts:

# The AI will automatically use the MCP to list all subaccounts
# No need to write code - just ask "List all Twilio subaccounts"

2. Get phone numbers for a subaccount:

# Simply ask: "Show me all phone numbers for subaccount AC..."

Direct Python Usage

For direct programmatic usage:

from mcp import ClientSession
from clients.client import MCPClient

async with MCPClient("uvx", ["twilio-manager-mcp"], env={}) as session:
    # List available tools
    tools = (await session.list_tools()).tools
    
    # List all subaccounts
    subaccounts = await session.invoke("list_twilio_subaccounts")
    
    # Get phone numbers for a subaccount
    numbers = await session.invoke("get_account_phone_numbers", {"account_sid": "AC..."})

Development

For development, you can use uv's virtual environment management:

# Create a virtual environment
uv venv

# Activate the virtual environment
source .venv/bin/activate  # On Unix
.venv\Scripts\activate     # On Windows

# Install dependencies in development mode
uv pip install -e .
