## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false}; The name "geo_navigate" says "navigate": a word for a change.
```


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `geo_style`

- The input addresses people (input.to): what it sends cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Configure semantic basemap styles. Operations: explain and schema retrieve public definitions; intent generates a proposal; preview compiles changes; save, list, revisions, diff, and delete manage profiles. Submit semantic manifests or preset patches, not raw MapLibre JSON. Authenticated operations affect the current key's profiles.
```

## Changes things (6)

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

### `elevation`

- 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
Sample terrain at lat/lon. elevationMeters is clamped to zero; sampledMeters retains the raw model elevation. belowSeaLevel identifies negative samples and bathymetryTile references the source raster. Requires a subscription key. Not survey-grade.
```

### `geo_navigate`

- The name "geo_navigate" says "navigate": 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
Navigation operations: route, matrix, isochrone, map_match, snap, and optimize. Route accepts 2–10 waypoints and optional elevation profiles. Matrix supports up to 625 pairs. Map matching accepts up to 1,000 trace points; optimization accepts 3–20 stops. Results include geometry or travel costs and source metadata. Requires a subscription key. Unroutable requests return an error and require revised inputs.
```

### `geo_render`

- 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
Render a static PNG map from a center and zoom or bounding box. Supports GeoJSON overlays, result handles, and up to 50 labeled markers. Dark and light styles use raster rendering; other preset or profile names use vector rendering. Requires a subscription key.
```

### `isochrone`

- 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
Calculate reachable-area polygons from a coordinate for up to four travel-time bands. Returns GeoJSON for catchment, coverage, and accessibility analysis. Requires a subscription key.
```

### `overpass_query`

- The name "overpass_query" says "query": a word for reading.
- The description's first verb is "execute": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Execute bounded Overpass QL over OSM nodes, ways, relations, tags, geometry, areas, metadata, and spatial selectors. Historical attic queries are unsupported. Requires a subscription key or authorized x402 payment. Use service_status to retrieve the dataset timestamp.
```

### `route`

- 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
Calculate a turn-by-turn route between 2–10 waypoints. Supported costing: auto, bicycle, pedestrian, truck, motor_scooter, and bus. Returns GeoJSON, distance, duration, and maneuvers. Set elevation to true for a terrain profile with gain and loss. Requires a subscription key.
```

## Only reads (6)

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

### `basemap_catalog`

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

Description, as the server wrote it:

```untrusted-server-text
List raster and vector tile templates, source zoom ranges, dataset snapshots, and attribution. The catalog is public; tile requests require a subscription key.
```

### `find_features`

- The name "find_features" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find cafes, restaurants, buildings, parks, schools, hospitals, transit stops, drinking water, or trails within a bounding box up to 0.5 degrees per axis. Returns OSM geometry and tags, subject to the output limit. Requires a subscription key or authorized x402 payment.
```

### `geo_analyze`

- The name "geo_analyze" says "analyze": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Measure or transform geometry using buffer, centroid, bbox, area, length, distance, intersect, union, difference, contains, intersects, nearest, simplify, or convex. Inputs accept GeoJSON, coordinate pairs, Overpass results, and result handles. Polygon overlay operations require areas. Use operation pipeline for up to 12 ordered steps and estimateOnly for cost estimation. Requires a subscription key.
```

### `geo_data`

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

Description, as the server wrote it:

```untrusted-server-text
Read service status, basemap catalog, point elevation, contours, usage, and metrics. Status includes subsystem availability and replication lag. Elevation returns surface and raw model heights. Metrics report request rates, success rates, latency percentiles, and dataset ages. Status and basemaps are public; other operations require a subscription key.
```

### `geo_search`

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

Description, as the server wrote it:

```untrusted-server-text
Search places and retrieve geographic entities. Use lookup for local address, business, brand and landmark search with soft map-focus bias, strict house numbers, source IDs and ambiguity reporting. Use discover for POIs in a viewport, polygon or isochrone, optionally ranked by travel time. Other operations: search, autocomplete, nearby, reverse, details, geocode, resolve, entity. Requires a subscription key.
```

### `service_status`

- The name "service_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read Overpass engine readiness, dataset timestamp, billing state, and x402 payment mode. Public. Use geo_data with operation status for the full subsystem report.
```
