## Quality 87/100 (good)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 3600000)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 69 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 1 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: nieruchomosci_online_search (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); nieruchomosci_online_offer (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 1,289 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name
- pass `stability.new_links`: no tool change named a new site

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 2, about 1,289 tokens to load them all
- tool set hash: a40a4d2f106be89b32d0d5706f09ff1f

## Tools (2)

- `nieruchomosci_online_offer`: Full details of one nieruchomosci-online.pl listing: price and price per m² (PLN), area, rooms, floor, year built, address with district and coordinates, seller type and name (agency, developer or private), the listing's detail table as shown on the page (Polish labels and values: rent and extra charges, deposit, building, heating, parking, source…), amenities, the full description and photo URLs. Get the id from nieruchomosci_online_search. Fetched live from nieruchomosci-online.pl (typically 1–3 s via direct fetch; up to ~20 s when it falls back to an unblocker). Result: { source, fetchedAt, listing: { id, url, title, property_type, transaction, kind, market, price, price_per_m2, currency, area_m2, rooms, floor, year_built, address, geo, seller_type, seller_name, agent_name, date_posted, updated, details, amenities, description, photos } }.
- `nieruchomosci_online_search`: Search property listings on nieruchomosci-online.pl, one of Poland's largest real-estate portals: flats, houses, plots, commercial premises and rooms, for sale or for rent, filtered by city/district or voivodeship, price, area, rooms and private-owner-only. Returns one results page (~40 listings) with each listing's price, price per m², area, rooms, floor, location, seller type and link; pass a listing `id` to nieruchomosci_online_offer for the full details. Fetched live from nieruchomosci-online.pl (typically 1–3 s via direct fetch; up to ~20 s when it falls back to an unblocker). Result shape: { source, fetchedAt, query, search_url, heading, resolved_location, total_count, page, total_pages, count, listings: [...], note? } — the list key is `listings`; `total_count` counts matches across all pages (use `page` for more). Each listing: { id, url, title, kind, market, price, price_per_m2, currency, area_m2, rooms, floor, location, street, city, region, seller_type, image, description }. Prices are numbers in PLN (for rent, `price` is the monthly rent) and area is in m²; fields are null when the page omits them. `kind` is 'new_development' for a developer's unit in a new project (primary market), else 'listing'; `seller_type` is agency | private | developer | company. An empty match answers count: 0 with a `note` saying why and what to change — that is a successful result, not an error.
