Book Window Cleaning

Security checks for vulnerabilities and agentic risk

Overview

This skill is a narrow window-cleaning booking helper that uses a disclosed external Lokuli MCP endpoint and does not include executable code or persistence.

Before installing, understand that booking through this skill will use Lokuli's external MCP service and a booking request may include your name, email, and phone number. Confirm the provider, time slot, and contact details before asking the agent to create a booking.

Missing User Warnings

Medium

Confidence: 96% confidence
Finding: The skill facilitates bookings through an external MCP endpoint and the documented booking payload includes personal contact details such as name, email, and phone number. Because the skill description does not warn users that this information will be transmitted to a third-party service, users may disclose sensitive personal data without informed consent, creating a privacy and compliance risk.
