- Version: `1.0.0`

## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 46/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 52/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 2607 tokens (~651/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (50% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-04 (score 57, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

### `gratka_search` (~950 tokens)

Search Polish real-estate listings (Gratka.pl)

Search property listings on Gratka.pl, a major Polish real-estate portal: flats, houses, plots, commercial premises, offices, garages and rooms, for sale or for rent, filtered by location (any Polish city, district, town, village, county or voivodeship), price, area, rooms, private sellers only and primary/secondary market, sorted like the site. Returns one results page (up to 35 listings) with each listing's price, price per m², area, rooms, floor, location, seller and link; pass a listing `id` to gratka_offer for the full details. Gratka.pl shows the same listings as Morizon.pl (one platform, different ids and links): search one portal, not both, and use gratka_offer only with Gratka.pl ids. Fetched live from Gratka.pl's own API (typically under 1 s). 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); `resolved_location` is the place `location` was matched to. Each listing: { source, id, url, title, category, kind, development, price, price_per_m2, currency, area_m2, rooms, floor, location, street, district, city, region, seller_type, seller_name, date_posted, refreshed_at, image, photo_count, description }. Prices are numbers in PLN (for rent, `price` is the monthly rent) and area is in m²; fields are null when the listing omits them. `kind` is 'new_development' for a developer's unit in a new project (named in `development`), else 'listing'; `seller_type` is agency | private | developer. An empty match answers count: 0 with a `note` saying why and what to change — that is a successful result, not an error.

Input parameters:

- `area_max` (number): Maximum area in m² (the plot's area for type 'plot').
- `area_min` (number): Minimum area in m² (the plot's area for type 'plot').

- `market` (string): 'primary' = new build from a developer (rynek pierwotny), 'secondary' = resale (rynek wtórny).
- `no_cache` (boolean): Force a fresh fetch and bypass this server's result cache (5 min). Default false.
- `page` (integer): Results page, 1-based (35 listings per page). Default 1.
- `price_max` (number): Maximum total price in PLN (monthly rent when transaction is 'rent').
- `price_min` (number): Minimum total price in PLN (monthly rent when transaction is 'rent').
- `private_only` (boolean): Only listings posted by private owners — no agencies or developers. Default false.
- `rooms_max` (integer): Maximum number of rooms — not for types 'plot' and 'garage' (use min = max for exactly N).

- `sort` (string): Order: 'newest' (recently added), 'price_asc' / 'price_desc', 'price_per_m2_asc' / 'price_per_m2_desc', 'area_asc' / 'area_desc'. Default: the site's own order (recently refreshed).
- `transaction` (string, required): 'sale' = na sprzedaż (buying), 'rent' = na wynajem (renting; prices are monthly).
- `type` (string, required): Property type: 'flat' = mieszkanie, 'house' = dom, 'plot' = działka/grunt (land), 'commercial' = lokal użytkowy (any commercial premises), 'office' = biuro, 'garage' = garaż, 'room' = pokój (a room t…
