Safety Controls

Modification Operations Protection

By default, all operations that can modify or delete OpenStack resources are disabled for safety:

# Default setting - Only read-only operations allowed
ALLOW_MODIFY_OPERATIONS=false

Protected Operations (when ALLOW_MODIFY_OPERATIONS=false):

• Instance management (start, stop, restart, pause, unpause)
• Volume operations (create, delete, attach, detach)
• Keypair management (create, delete, import)
• Floating IP operations (create, delete, associate, disassociate)
• Snapshot management (create, delete)
• Image management (create, delete, update)
• Heat stack operations (create, delete, update)

Always Available (Read-Only Operations):

• Cluster status and monitoring
• Resource listings (instances, volumes, networks, etc.)
• Service status checks
• Usage and quota information
• Search and filtering operations

⚠️ To Enable Modify Operations:

# Enable all operations (USE WITH CAUTION)
ALLOW_MODIFY_OPERATIONS=true

Tool Registration Behavior:

• When ALLOW_MODIFY_OPERATIONS=false: Only read-only tools are registered with the MCP server
• When ALLOW_MODIFY_OPERATIONS=true: All tools (read-only + modify operations) are registered
• Tool availability is determined at server startup - restart required after changing this setting

Best Practices:

• Keep ALLOW_MODIFY_OPERATIONS=false in production environments
• Enable modify operations only in development/testing environments
• Use separate configurations for different environments
• Review operations before enabling modify capabilities
• Restart the MCP server after changing the ALLOW_MODIFY_OPERATIONS setting

Performance Optimization

Large-Scale Environment Support

The MCP server is optimized for large OpenStack environments with thousands of instances:

Pagination Features:

• Default limits prevent memory overflow (50 instances per request)
• Configurable safety limits (maximum 200 instances per request)
• Offset-based pagination for browsing large datasets
• Performance metrics tracking (processing time, instances per second)

Search Optimization:

• 2-phase search process (basic info filtering → detailed info retrieval)
• Intelligent caching with connection reuse
• Selective API calls to minimize overhead
• Case-sensitive search options for precise filtering

Connection Management:

• Global connection caching with validity testing
• Automatic retry mechanisms for transient failures
• Connection pooling for high-throughput scenarios

Usage Examples:

# Safe large environment browsing
get_instance_details(limit=50, offset=0)     # First 50 instances
get_instance_details(limit=50, offset=50)    # Next 50 instances

# Emergency override for small environments
get_instance_details(include_all=True)       # All instances (use with caution)

# Optimized search for large datasets
search_instances("web", "name", limit=20)    # Search with reasonable limit

Development

Adding New Tools

Edit src/mcp_openstack_ops/mcp_main.py to add new MCP tools:

@mcp.tool()
async def my_openstack_tool(param: str) -> str:
    """
    Brief description of the tool's purpose.
    
    Functions:
    - List specific functions this tool performs
    - Describe the operations it enables
    - Mention when to use this tool
    
    Use when user requests [specific scenarios].
    
    Args:
        param: Description of the parameter
        
    Returns:
        Description of return value format.
    """
    try:
        logger.info(f"Tool called with param: {param}")
        # Implementation using functions.py helpers
        result = my_helper_function(param)
        
        response = {
            "timestamp": datetime.now().isoformat(),
            "result": result
        }
        
        return json.dumps(response, indent=2, ensure_ascii=False)
        
    except Exception as e:
        error_msg = f"Error: Failed to execute tool - {str(e)}"
        logger.error(error_msg)
        return error_msg

Helper Functions

Add utility functions to src/mcp_openstack_ops/functions.py:

def my_helper_function(param: str) -> dict:
    """Helper function for OpenStack operations"""
    try:
        conn = get_openstack_connection()
        
        # OpenStack SDK operations
        result = conn.some_service.some_operation(param)
        
        logger.info(f"Operation completed successfully")
        return {"success": True, "data": result}
        
    except Exception as e:
        logger.error(f"Helper function error: {e}")
        raise

Testing & Validation

Local Testing

# Test with MCP Inspector (recommended)
./scripts/run-mcp-inspector-local.sh

# Test with debug logging
MCP_LOG_LEVEL=DEBUG uv run python -m mcp_openstack_ops

# Validate OpenStack connection
uv run python -c "from src.mcp_openstack_ops.functions import get_openstack_connection; print(get_openstack_connection())"

🔐 Security & Authentication

Bearer Token Authentication

For streamable-http mode, this MCP server supports Bearer token authentication to secure remote access. This is especially important when running the server in production environments.

Configuration

Enable Authentication:

# In .env file
REMOTE_AUTH_ENABLE=true
REMOTE_SECRET_KEY=your-secure-secret-key-here

Or via CLI:

uv run python -m mcp_openstack_ops --type streamable-http --auth-enable --secret-key your-secure-secret-key-here

Security Levels

1. stdio mode (Default): Local-only access, no authentication needed
2. streamable-http + REMOTE_AUTH_ENABLE=false/undefined: Remote access without authentication ⚠️ NOT RECOMMENDED for production
3. streamable-http + REMOTE_AUTH_ENABLE=true: Remote access with Bearer token authentication ✅ RECOMMENDED for production

🔒 Default Policy: REMOTE_AUTH_ENABLE defaults to false if undefined, empty, or null. This ensures the server starts even without explicit authentication configuration.

Client Configuration

When authentication is enabled, MCP clients must include the Bearer token in the Authorization header:

{
  "mcpServers": {
    "openstack-ops": {
      "type": "streamable-http",
      "url": "http://your-server:8000/mcp",
      "headers": {
        "Authorization": "Bearer your-secure-secret-key-here"
      }
    }
  }
}

Security Best Practices

• Always enable authentication when using streamable-http mode in production
• Use strong, randomly generated secret keys (32+ characters recommended)
• Use HTTPS when possible (configure reverse proxy with SSL/TLS)
• Restrict network access using firewalls or network policies
• Rotate secret keys regularly for enhanced security
• Monitor access logs for unauthorized access attempts

Error Handling

When authentication fails, the server returns:

• 401 Unauthorized for missing or invalid tokens
• Detailed error messages in JSON format for debugging
