World Clock Pro: Time & Timezone Converter

Security checks for vulnerabilities and agentic risk

Overview

The skill is a small world-clock integration that clearly discloses its use of the worldclock.pro MCP endpoint and does not request local files, credentials, persistence, or mutation authority.

Install this if you are comfortable with time, location, coordinate, or meeting-conversion queries being sent to worldclock.pro for live results. Avoid entering sensitive meeting details if the location/time query itself would reveal private information.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
