### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session

## Tools (3)

- `get_listing`: Full details of one listing by id (e.g. 'c-152' or 'b-7'): full description, photos, dates. If `latest_id` is set, this is an older copy of a reposted listing — use the newest one instead.
- `list_regions`: Regions and areas of Northern Cyprus with the number of current listings (rent and sale), names in English and Russian. Use to pick `region` / `sub_region` for search_listings.
- `search_listings`: Search current property listings in Northern Cyprus. All filters are optional and accept English, Russian or Turkish spellings (e.g. region 'Kyrenia' or 'Гирне'). Returns up to `limit` listings (featured first, then newest by default) with a one-line `summary`, `url` and `contact_url`. Example: long-term rent of a 2+1 in Iskele up to £700 → deal='Rent', region='iskele', layout='2+1', price_max=700, price_period='month'.
