Security checks across malware telemetry and agentic risk

Overview

This is a straightforward NOAA marine-weather MCP skill, with ordinary supply-chain cautions around its unpinned npx install.

Before installing, confirm the exact npm package name and prefer pinning a known version instead of a floating npx install. Expect entered coordinates to be sent to NOAA weather services for forecast lookup.

Finding
The skill invokes an external package via `npx` and inherently requires network access to reach NOAA, but it does not declare any permissions or capability expectations to the user. This creates a transparency and trust problem: consumers may approve or run the skill without understanding that it can access the network and potentially read environment variables available to the spawned process.
