Finding

The skill explicitly instructs sending customerName, customerEmail, and customerPhone to an external MCP endpoint for booking, but it provides no user-facing notice, consent step, or data-minimization guidance. This creates a privacy and compliance risk because personal contact information may be transmitted to a third party without adequate transparency or confirmation.
