THE RISK

Low Risk

Why determine-flight-category needs a policy

This tool analyzes and interprets provided weather conditions to categorize flight safety levels. It is a read-only computation that retrieves no new data, modifies nothing, and produces informational output only. Even though the output could inform safety-critical decisions, the tool itself performs no side effects and poses minimal risk of misuse.

From the tool's definition Tool name 'determine-flight-category' and description 'Determine the flight category (VFR/MVFR/IFR/LIFR) for given weather conditions' indicate a classification/analysis function that processes existing weather data to produce categorical output.

POLICY

How to control determine-flight-category

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 determine-flight-category:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "determine-flight-category": {}
  }
}

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

Create a free account and register Aviation Weather MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
