get-airmets · Aviation Weather MCP Server MCP: Risk & Policy

WHAT IT DOES

What get-airmets does on Aviation Weather MCP Server

AI agents call get-airmets to retrieve information from Aviation Weather MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why get-airmets needs a policy

This tool retrieves existing aviation weather data (AIRMETs - Airmen's Meteorological Information) from aviationweather.gov. It performs a read-only query with no capability to modify, delete, execute code, or cause financial impact. The worst-case misuse would be providing incorrect or outdated weather information to a user, which is a low-severity informational risk, not operational.

From the tool's definition Tool name 'get-airmets' and description 'Fetch current AIRMETs' indicate data retrieval with no modification or side effects. AIRMETs are aviation weather advisories that are queried, not altered.

POLICY

How to control get-airmets

PolicyLayer is an MCP gateway — it sits between your AI agents and Aviation Weather MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get-airmets:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get-airmets": {}
  }
}

get-airmets is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
