Twilio Manager MCP server

The TwilioManager MCP connects Claude AI to Twilio through the Model Context Protocol, enabling AI-assisted management of Twilio accounts, phone numbers, and regulatory compliance. This integration creates a direct connection between Claude and Twilio's API for streamlined operations.

Installation

Prerequisites

• Python 3.10 or newer
• uv package manager

For Mac:

brew install uv

For Windows:

powershell -c "irm https://astral.sh/uv/install.ps1 | iex"
set Path=C:\Users\[USERNAME]\.local\bin;%Path%

⚠️ Do not proceed before installing UV

Environment Setup

1. Clone the repository
2. Copy .env.example to .env and add your Twilio credentials:

TWILIO_ACCOUNT_SID=your_account_sid
TWILIO_AUTH_TOKEN=your_auth_token

3. Install dependencies:

uv pip install -e .

Claude for Desktop Integration

Edit your Claude Desktop configuration file:

1. Go to Claude > Settings > Developer > Edit Config > claude_desktop_config.json
2. Add the following:

{
    "mcpServers": {
        "twilio": {
            "command": "uvx",
            "args": [
                "twilio-manager-mcp"
            ]
        }
    }
}

Cursor Integration

To run without permanent installation, go to Cursor Settings > MCP and paste:

uvx twilio-manager-mcp

⚠️ Only run one instance of the MCP server (either on Cursor or Claude Desktop), not both

Usage

Starting the Connection

1. Ensure your credentials are set in the .env file
2. Start the MCP server:

uvx twilio-manager-mcp

3. In Claude, look for the Twilio MCP tool icon in the toolbar

Capabilities

The Twilio Manager MCP allows you to:

• List and filter Twilio subaccounts
• View phone numbers associated with accounts
• Transfer phone numbers between accounts
• Create and manage addresses
• Handle regulatory compliance and bundles
• Execute comprehensive Twilio account management tasks

Example Commands

Here are some examples of what you can ask Claude to do:

• "List all my Twilio subaccounts"
• "Show all phone numbers on my main account"
• "Transfer phone number X from account A to account B"
• "Create a new address for regulatory compliance"
• "Duplicate a regulatory bundle to a subaccount"
• "Show all phone numbers of a specific type"

Troubleshooting

• Connection issues: Make sure the MCP server is running and configured on Claude
• Authentication errors: Verify your Twilio credentials in the .env file
• Rate limiting: Twilio API has rate limits; consider adding delays between operations if hitting limits
• Timeout errors: Try simplifying your requests or breaking them into smaller steps

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "twilio" '{"command":"uvx","args":["twilio-manager-mcp"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "twilio": {
            "command": "uvx",
            "args": [
                "twilio-manager-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "twilio": {
            "command": "uvx",
            "args": [
                "twilio-manager-mcp"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
