This tool retrieves calendar event data from Outlook without creating, modifying, deleting, or executing any actions. It is a pure read operation with minimal security risk. Even if an AI agent misuses it by reading calendar events it shouldn't access, the worst case is information disclosure (typically low severity unless the calendar contains highly sensitive data, but the tool itself poses no inherent risk).
