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. How we score → Why this is hard to score →
Endpoint Security46
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 2 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability47
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1175 tokens (~587/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management10
- Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (50% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

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.

The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

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 Polish real-estate listings (nieruchomosci-online.pl) ~780
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.
