Swiss-Weather

Security checks across malware telemetry and agentic risk

Overview

This skill is a straightforward Swiss weather helper that fetches public MeteoSwiss weather data and shows no hidden access, persistence, or destructive behavior.

Safe to install for Swiss weather lookups. Be aware that forecast queries send the requested Swiss postal code to MeteoSwiss, and use a trusted Python environment if you choose the optional requests-based scripts.

MCP Least Privilege
Confidence
88% confidence
Finding
The skill documentation instructs the agent to invoke shell scripts and Python programs that make network requests, yet the skill declares no permissions for those capabilities. This creates a transparency and policy-enforcement gap: an orchestrator or reviewer may treat the skill as low-risk while it can still trigger command execution and external data access.
