## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `autocomplete_regions`

- 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
Suggest holiday regions by (partial) name, typo-tolerant. Names are matched in the response language, with German (the native names, e.g. "Seenplatte") always accepted as well. Returns region ids usable as regionId in search_accommodations, with accommodation counts.
```

## Only reads (3)

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

### `get_accommodation`

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

Description, as the server wrote it:

```untrusted-server-text
Full localized detail of one accommodation: description, location with coordinates, capacity, rating, feature codes, image gallery, base price, and `url` (the listing page on the website of the locale).
```

### `get_accommodation_availability`

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

Description, as the server wrote it:

```untrusted-server-text
Per-day availability for one accommodation: bookable days, arrival/departure flags, minimum stay, nightly price and discounts. Window defaults to today and is capped at 24 months.
```

### `search_accommodations`

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

Description, as the server wrote it:

```untrusted-server-text
Paginated holiday accommodation search over directly bookable/inquirable own inventory (externally managed listings are not exposed). Filter by region (regionId from autocomplete_regions), a radius around a point (lat/lng/radiusKm — use the coordinates of the place the user names; results then carry distanceKm and can be sorted by distance) or a map bounding box (neLat/neLng/swLat/swLng); these three are mutually exclusive. Travel dates (arrival/departure, both together; add bookableOnly to drop stays below the minimum stay), persons (a minimum: beds ≥ persons — add personsMax to exclude oversized houses; optional adults split for families — children can use extra-children slots), bedrooms, bathrooms, livingSpaceMin (m²), minReviews, price range per night, feature codes (e.g. swimming_pool, wifi, pets_allowed), accommodation types and offers. Sort: relevance (default), rating (best first; website formula, a single 5.0 review outranks many 4.8s — use minReviews), persons, bedrooms, living_area, distance (radius searches). Every result carries `url` (the listing page on the website of the locale) and, on dated searches, `stayUrl` with dates and guests pre-filled — give these to the user as the link. `location.place` is the actual town; `location.region` is the (marketing) region it is listed under. Dated searches include a stayPrice per result: the exact total for the stay incl. mandatory costs and discounts (kind "total"; "min_stay" when the stay is below the minimum), or "from"/"on_request" where only the static basePrice or no price is available. `approximate: true` means some nights were priced from the owner's base price; the website confirms the final total.
```
