# adw.air_quality_risk

County-level air-quality index from EPA AQS annual summaries (ADW-308). Returns national percentile rank, band, median AQI, % unhealthy days, and p90 AQI. Pass county as a 5-digit county FIPS (e.g. '12011') or 'County Name, ST' (e.g. 'Broward County, FL'). Only EPA-monitored counties (~700-1,000 of 3,143) are covered; unmonitored counties return null.

## Why adw.air_quality_risk is rated Low

This tool queries and retrieves historical air quality index data from EPA datasets. It performs no side effects, creates no data, executes no code, and cannot delete or modify records. The parameters (county FIPS or name) are simple lookup keys.

From the tool's own definition: "Tool description states it 'Returns national percentile rank, band, median AQI, % unhealthy days, and p90 AQI' — purely retrieval of pre-computed EPA air quality summaries with no modification, deletion, or execution capability."

## Use case

AI agents call adw.air_quality_risk to retrieve information from AlpineDataWorks Intelligence Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches AlpineDataWorks Intelligence Server:

```json
{
  "version": "1",
