Installation

Using uv (Recommended)

When using uv, no installation is necessary. Instead, you can simply invoke the server directly from Github with the uvx command

Configuration

The server requires the following environment variables:

Required Variables

• USERNAME - Your cPanel username
• HOSTNAME - Your cPanel hostname (e.g., example.com or server.example.com)
• CPANEL_API_TOKEN - Your cPanel API token

Optional Variables

• PORT - cPanel port (default: 2083)
• SSL - Enable SSL connection (default: true)

Getting a cPanel API Token

1. Log into your cPanel account
2. Navigate to Security → Manage API Tokens
3. Click Create Token
4. Give it a descriptive name (e.g., "MCP Server")
5. Set appropriate restrictions if needed
6. Copy the generated token

Usage

MCP Client Configuration

Add the server to your MCP client configuration (e.g., Claude Desktop):

Example Usage

Once connected to an MCP client, you can use natural language commands:

• "Create a new email account support@example.com with password SecurePass123"
• "List all email accounts for example.com"
• "Set up email forwarding from info@example.com to admin@example.com"
• "Change the password for user@example.com to NewPassword456"
• "Delete the email account temp@example.com"
• "Update the quota for sales@example.com to 1000 MB"

Security Considerations

• API Token Security: Never commit your API token to version control
• Environment Variables: Use environment variables or secure secret management
• Network Security: Ensure your cPanel server supports HTTPS (SSL)
• Password Policy: Use strong passwords for email accounts

Troubleshooting

Common Issues

1. Authentication Errors
   • Verify your API token is correct and active
   • Check that your username matches your cPanel account
   • Ensure the hostname includes the correct domain/subdomain
2. Connection Issues
   • Verify the hostname and port are correct
   • Check if SSL is properly configured
   • Ensure your server allows API connections
3. Permission Errors
   • Verify your cPanel account has email management permissions
   • Check if the API token has the necessary privileges
