### `get_air_quality`

- The name "get_air_quality" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the current air quality for a city, from real-time monitoring
and atmospheric model data. Use for any "what's the air quality in X",
"is it safe to go outside in Y", "how polluted is Z" style question, or
whenever pollen/smog/wildfire-smoke/pollution conditions are relevant
to a plan (running, cycling, sensitive-groups advice, travel).

`city` is a free-text place name (e.g. "Bangkok", "Berlin", "Springfield, US").

Returns a dict with:
- `location`: resolved place name/country/admin1
- `us_aqi`: the current US Air Quality Index (0-500+)
- `aqi_category`: plain-language category computed from `us_aqi` --
  "Good" (0-50), "Moderate" (51-100), "Unhealthy for Sensitive Groups"
  (101-150), "Unhealthy" (151-200), "Very Unhealthy" (201-300), or
  "Hazardous" (301+); "Unknown" if no AQI could be resolved for that
  location
- `pm2_5`, `pm10`: particulate matter concentrations (ug/m3)
- `ozone`, `nitrogen_dioxide`, `sulphur_dioxide`, `carbon_monoxide`:
  trace gas concentrations (ug/m3)
- `local_time`: the timestamp of the reading, in the location's local time
- `attribution`
```

## Claude Code permissions

  "permissions": {
    "allow": [
      "mcp__air-quality__get_air_quality"
    ],
    "ask": [],
    "deny": []
  }
