## Findings

- **warn** Annotations that disagree with the tool in `geocode` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "geocode" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The description's first verb is "convert": a word for a change.
```


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `geocode`

- The description's first verb is "convert": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Convert a US street address OR a city/town name into latitude/longitude coordinates, using US Census data. Accepts both '1600 Pennsylvania Ave NW, Washington DC' and 'Chicago, IL' - a place name returns the centroid of the city. Call this first whenever you have a location as text and need coordinates for the weather or elevation tools. US locations only.
```

## Only reads (5)

Looks things up and changes nothing. Claude Code: allow.

### `earthquakes`

- The description's first verb is "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List recent earthquakes worldwide from the USGS feed. Filter by minimum magnitude, look-back window in days, and optionally a bounding box or a point+radius (km). Returns magnitude, place, time, depth and coordinates.
```

### `elevation`

- The description's first verb is "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the ground elevation at a latitude/longitude within the US, from the USGS Elevation Point Query Service. Returns elevation in feet and meters.
```

### `weather_alerts`

- The description's first verb is "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List active NWS weather alerts (warnings, watches, advisories) for a US state or marine area. Pass a two-letter state code like CA, TX, FL. Returns event type, severity, headline, affected area and expiry.
```

### `weather_current`

- The description's first verb is "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get the latest observed weather conditions for a US location by latitude/longitude, from the nearest NWS observation station: temperature, humidity, wind, and text description.
```

### `weather_forecast`

- The description's first verb is "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Get a multi-day weather forecast for a US location by latitude/longitude (National Weather Service). Returns named periods (Today, Tonight, ...) with temperature, wind, and a short + detailed forecast. Use geocode first if you only have an address.
```
