## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `maptiler_batch_geocode`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Forward-geocode up to 50 queries in one request. Returns a JSON ARRAY of GeoJSON FeatureCollections, one per query, in order. API: GET /geocoding/{q1;q2;...}.json.
```

### `maptiler_geolocate_ip`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Geolocates the IP address making the request — from a hosted Worker this is the server's egress IP, not the end-user's. API: GET /geolocation/ip.json.
```

### `maptiler_transform_coordinates`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Transform up to 50 coordinate pairs from a source coordinate reference system to a target one (EPSG codes). API: GET /coordinates/transform/{coordinates}.json.
```

## Only reads (5)

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

### `maptiler_geocode`

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

Description, as the server wrote it:

```untrusted-server-text
Search for a place, address, or POI by name and get matching locations as GeoJSON features. e.g. 'Zurich' or '1600 Pennsylvania Ave'. API: GET /geocoding/{query}.json.
```

### `maptiler_get_data_features`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch the GeoJSON FeatureCollection of a MapTiler-hosted dataset by its data id. API: GET /data/{dataId}/features.json.
```

### `maptiler_get_elevation`

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

Description, as the server wrote it:

```untrusted-server-text
Look up ground elevation at up to 50 coordinates. Returns an array of [lng, lat, elevation] triples. API: GET /elevation/{locations}.json.
```

### `maptiler_reverse_geocode`

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

Description, as the server wrote it:

```untrusted-server-text
Find the place(s) at a given longitude/latitude, returned as GeoJSON features. API: GET /geocoding/{longitude},{latitude}.json.
```

### `maptiler_search_coordinate_systems`

- The name "maptiler_search_coordinate_systems" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search MapTiler's CRS/EPSG database by free text or key:value filters (e.g. 'code:4326', 'kind:CRS-PROJCRS'). API: GET /coordinates/search/{query}.json.
```
