### `air_quality`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Current air quality for a place: PM2.5, PM10, ozone, NO2, SO2, CO and dust, plus the US and European AQI and the US AQI band ('Good', 'Unhealthy'). Takes a place name — no coordinates needed. (Free. This server also sells a paid API — call `paid_catalogue` for the routes and prices; x402 over USDC on Base, no signup.)
```

### `country_indicator`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
