## 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 2026-10-18.

- **Endpoint Security**: 63/100
  - 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 14 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 is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 72/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1360 tokens (~97/item across 14 items; 14 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 84/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 44% of tool parameters carry a description.
  - Structured output schemas are declared (21% 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 14 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 14 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (14)

### `search_tenders` (~181 tokens)

Semantic search over active Polish public tenders (przetargi) by meaning, with optional filters. Ranks by relevance (hybrid vector + keyword). Returns paginated tender cards, each with a public URL. Only publicly-servable tenders with an AI summary are returned. `mode` is 'semantic', or 'lexical' when the embedding service is temporarily unavailable.

Input parameters:

- `cpv` (string): Restrict to tenders whose CPV includes this code
- `deadline_before` (string): ISO date; only tenders with submission deadline before it
- `max_value` (number): Maximum estimated value (PLN)
- `min_value` (number): Minimum estimated value (PLN)
- `page` (integer)
- `query` (string, required): Natural-language query, e.g. 'budowa hali sportowej z basenem'

Output parameters:

- `filter` (string)
- `has_more` (boolean)
- `mode` (string)
- `page` (number)
- `per_page` (number)
- `query` (string)
- `tenders` (array)
- `total` (number)

### `list_tenders` (~159 tokens)

Browse tenders without a text query. `filter` selects the axis: 'all' (every active tender, or archived when archived=true), 'category' (CPV division code from list_facets), 'region' (voivodeship slug from list_facets), or 'city' (city slug from list_facets). Use list_facets first to get valid values.

Input parameters:

- `archived` (boolean): Only for filter='all': return finished tenders instead.
- `filter` (string)
- `page` (integer)
- `value` (string): Required for category/region/city. CPV division code (e.g. '45000000'), region slug, or city slug — all from list_facets.

Output parameters:

- `filter` (string)
- `has_more` (boolean)
- `mode` (string)
- `page` (number)
- `per_page` (number)
- `query` (string)
- `tenders` (array)
- `total` (number)

### `list_facets` (~57 tokens)

List the browsable facets of the active tender set: CPV categories, voivodeships (regions), and cities, each with a count and the slug/code to pass to list_tenders. Call this to discover valid filter values.

### `get_tender` (~121 tokens)

Fetch full detail for one tender by its public slug (from search_tenders/list_tenders results): metadata, the 12-section AI SWZ summary, the OPZ scope brief, full award results (winner, value, offer price band, rejected offers, whether the cheapest offer won), the cancelled predecessor it re-issues (with that procedure's offer band — a price signal), the EU project funding it, and the bidders' Q&A. Returns not-found for non-public tenders.

Input parameters:

- `slug` (string, required): public_slug from a listing result

Output parameters:

- `authority` (object)
- `cancelled_predecessor`
- `cpv` (array)

- `results` (array)
- `scope_brief`
- `slug`
- `source` (string)
- `submission_deadline`
- `summary_sections`
- `title` (string)
- `url`

### `search_entities` (~108 tokens)

Find contracting authorities (kind='buyer', zamawiający) or contractors (kind='contractor', wykonawcy — companies and sole traders) by name or NIP. Returns each match with its slug and public URL; pass the slug to get_buyer / get_contractor.

Input parameters:

- `limit` (integer)
- `query` (string, required): Name fragment or NIP, e.g. 'gmina wieliczka' or '6772...'

### `get_buyer` (~104 tokens)

Profile of one contracting authority (zamawiający) by slug (from search_entities or a tender's authority): identity (NIP, REGON, KRS, region), counts, its active tenders, recent awards with winners, top contractors, procurement plan positions and recent contracts — or, on older pages, its tenders and public finance (municipal budget, NFZ contracts, investments). Same data as its public page.

Input parameters:

- `slug` (string, required)

### `get_contractor` (~91 tokens)

Profile of one contractor (wykonawca — company or sole trader) by slug (from search_entities or a buyer's results): registry data (REGON, legal form, VAT status, PKD, debtor-register flags), wins and offers, recent wins and losses, its main buyers, rivals it meets, and recent public contracts. Same data as its public page.

Input parameters:

- `slug` (string, required)

### `cpv_stats` (~217 tokens)

Monthly market statistics for one CPV category, as on its public statistics page: awards with a price, median and p10/p90 award value, average offers per award, distinct winners, top winners, biggest awards and the regional split.
