cPanel MCP Server

A complete Model Context Protocol (MCP) server for managing cPanel hosting through AI assistants like Claude Code

---

🎯 Overview

This is a production-ready MCP server that enables natural language management of cPanel hosting accounts through AI assistants. Built from scratch with TypeScript, it provides 16 tools for comprehensive hosting management.

Why This Exists: The original cPanel MCP repository contained only documentation with no source code. This is a complete, working implementation that you can use today.

📖 Usage Examples

Natural Language Commands

Once configured, you can use natural language to manage your hosting:

File Operations:

"List files in public_html directory"
"Read the contents of wp-config.php"
"Create a new file called test.html with Hello World"
"Delete the old-backup.tar.gz file"

Database Operations:

"Show me all databases"
"Create a new database called my_app_db"
"Delete the test_database database"

Email Management:

"List all email accounts"
"Create email account support@example.com with password SecurePass123"
"Delete email account old@example.com"

Subdomain Management:

"List all subdomains"
"Create subdomain 'blog' under example.com"
"Delete subdomain test.example.com"

System Information:

"Check disk usage"
"How much storage am I using?"
"Start a full account backup"

Direct Tool Calls

You can also call tools directly:

// List files
mcp__cpanel__list_files({ dir: "/public_html" })

// Read file
mcp__cpanel__read_file({ file: "/public_html/index.php" })

// Create database
mcp__cpanel__create_database({ name: "myapp" })

// Check disk usage
mcp__cpanel__disk_usage()

🔐 Security

Generating a cPanel API Token

1. Log into your cPanel account
2. Go to Security → Manage API Tokens
3. Click Create to generate a new token
4. Copy the token and save it securely
5. Add it to your .env file

Best Practices

• ✅ Never commit .env file - Contains sensitive credentials
• ✅ Use API tokens, not passwords - More secure and can be revoked
• ✅ Rotate tokens regularly - Update every 90 days
• ✅ Use least privilege - Only grant necessary permissions
• ✅ Monitor access logs - Check cPanel logs regularly

Security Features

• Environment-based credential storage
• HTTPS/SSL encrypted API communication
• Basic authentication with API tokens
• No credentials in source code or logs
• Comprehensive .gitignore for sensitive files

🧪 Testing

Verify Installation

# Check Node.js version
node --version  # Should be 18+

# Build the server

🐛 Troubleshooting

Server Won't Start

Problem: MCP server fails to start

Solutions:

• Verify Node.js is installed: node --version
• Check build output exists: ls build/index.js
• Rebuild: npm run build
• Check logs for error messages

Authentication Errors

Problem: "401 Unauthorized" or "403 Forbidden"

Solutions:

• Verify API token is correct in .env
• Check username format: user@domain.com
• Confirm cPanel URL includes port :2083
• Test credentials directly in cPanel
• Generate new API token if expired

File Paths Not Working

Problem: File operations fail

Solutions:

• Use absolute paths starting with /
• Check file permissions in cPanel
• Verify directory exists
• Test with cPanel File Manager first
