## 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 2026-09-25.

- **Endpoint Security**: 83/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 47/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1390 tokens (~1390/item across 1 items; 1 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 50/100
  - Stability observed for 15 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 (100% 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 1 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

Hledání pronájmů bytů

Najde pronájmy bytů v Česku podle zadaných kritérií. Vrátí prvních deset nabídek, celkový počet a odkaz na celý výpis na bydleno.cz. Všechny parametry jsou volitelné a bez nich dostaneš nejnovější nabídky; zadávej jen ta kritéria, která uživatel řekl. Nejčastěji stačí location_texts, layout_id a price_range_to. Hodnoty výčtů piš přesně jako popisky ze schématu ("2+kk", "Vybavený"); hodnotu mimo výčet i neznámý parametr zahodíme.

Když nic neodpovídá, vrátí nulový počet a odkaz na výpis; když hledání selže, vrátí isError a text chyby. Vždy nabídni uživateli odkaz na výpis i na jednotlivé nabídky.
