Installation & Setup

Prerequisites

• Python 3.11+
• Redis server (for caching and session management)
• Cloudways API credentials

1. Configure environment variables:

   # Generate encryption key for secure credential storage
   export ENCRYPTION_KEY=$(python -c 'from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())')
   
   # Redis configuration
   export REDIS_URL="redis://localhost:6379/0"
   
   # Optional performance tuning
   export REDIS_POOL_SIZE="500"
   export HTTP_POOL_SIZE="500"
   export RATE_LIMIT_REQUESTS="90"
   export RATE_LIMIT_WINDOW="60"
   

Encryption Key Management

The server requires a Fernet encryption key for secure credential storage.

Generating a New Key

# Generate and set encryption key
export ENCRYPTION_KEY=$(python -c 'from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())')

Exporting an Existing Key

# Save current key to file
echo $ENCRYPTION_KEY > encryption_key.txt

# Create environment file
echo "ENCRYPTION_KEY=$ENCRYPTION_KEY" > .env

# Load from environment file
export $(cat .env | xargs)

Key Validation

# validate_key.py
from cryptography.fernet import Fernet
import os

key = os.getenv('ENCRYPTION_KEY')
if not key:
    print("ENCRYPTION_KEY not set")
    exit(1)

try:
    fernet = Fernet(key.encode())
    test_data = b"test"
    encrypted = fernet.encrypt(test_data)
    decrypted = fernet.decrypt(encrypted)

    if decrypted == test_data:
        print("Encryption key is valid")
    else:
        print("Key validation failed")
except Exception as e:
    print(f"Invalid encryption key: {e}")

Important Notes

• Key must be 44 characters long (base64-encoded)
• Generated using Fernet.generate_key()
• Do not commit keys to version control
• Changing the key invalidates existing encrypted data in Redis

3. Start the server:

   python main.py
   

   Server will be available at: http://localhost:7000/mcp

Authentication

The server uses header-based authentication with encrypted credential storage:

x-cloudways-email: <your-cloudways-email>
x-cloudways-api-key: <your-cloudways-api-key>

Security Features

• Credential Encryption: API keys encrypted with Fernet before Redis storage
• Session Isolation: Unique customer ID generation prevents session cross-contamination
• Token Auto-Renewal: OAuth token refresh before expiration
• Rate Limiting: Token bucket algorithm (90 requests/60 seconds by default)
• Input Validation: Parameter validation with range checks
• Audit Logging: Request/response logging with structured data

Configuration Options

Variable	Default	Description
ENCRYPTION_KEY	Required	Fernet encryption key for credential storage
REDIS_URL	redis://localhost:6379/0	Redis connection string
REDIS_POOL_SIZE	500	Redis connection pool size
HTTP_POOL_SIZE	500	HTTP connection pool size
RATE_LIMIT_REQUESTS	90	Requests per time window
RATE_LIMIT_WINDOW	60	Rate limit window (seconds)
LOG_LEVEL	INFO	Logging verbosity
LOG_FORMAT	console	Log format (console/json)

Monitoring & Observability

Structured Logging

• Performance Metrics: Request timing and resource usage
• Security Events: Authentication failures, rate limiting
• API Interactions: Request/response logging with sanitized credentials
• Error Tracking: Error context and stack traces

Health Checks

• ping - Basic connectivity and authentication test
• rate_limit_status - Current rate limit status
• customer_info - Session and authentication status

Development & Extension

Adding New Tools

1. Choose appropriate module in tools/ directory
2. Follow existing patterns for error handling and authentication
3. Use type hints with Pydantic models for parameters
4. Include docstrings
5. Test with various authentication scenarios
