## 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 2026-11-04.

- **Endpoint Security**: 74/100
  - 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.
  - 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**: 60/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1428 tokens (~476/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 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 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 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).

### `search_listings` (~781 tokens)

Search Spanish auction listings

Search active Spanish court auctions (BOE section IV), State/public-body sales (BOE section V-B) and Social Security auctions (TGSS). Sources: the BOE (Agencia Estatal Boletín Oficial del Estado) for court auctions (section IV) and State sales (section V-B), and the TGSS (Tesorería General de la Seguridad Social) for Social Security auctions. Only active listings are returned: a listing whose bid deadline (Europe/Madrid date) has passed is left out, checked on every request. Use it first to find listings by province, town, type, asset type, starting price or dates; then call get_listing with an id for the full record. Returns total count, paging (limit/offset) and short records: id, title in 5 languages, approximate place, seller, starting price in EUR when the notice gives one, publication date, deadline, HammerMap risk light and links (HammerMap page, official channel, BOE notice when there is one). Coverage: Spain only. Data are updated once per working day; attribution.data_updated and attribution.latest_boe_publication show how fresh they are. Court auction notices in BOE open data have no price, description or closing date (those are on the official portal). All filters are optional and combine with AND.

Input parameters:
