## 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 2026-08-04.

- **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 21 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**: 39/100
  - 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 3294 tokens (~149/item across 22 items; 21 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 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.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

Aggregated search by VIN across all car-kinds (ОТТС/ОТШ/ЗОТТС/ЗОТШ/
    СБКТС/ЗОЕТС). Open for any active API key — no subscription required.

    Returns documents whose VIN field contains the given fragment, newest
    first. For exact full-VIN search within a single registry use the
    per-kind tool (search_otts/search_sbkts/…) with its `vin` parameter.

Input parameters:

- `vin` (string, required): VIN substring or full code (5-17 chars).

Output parameters:

- `result` (string)

### `fulltext_search` (~196 tokens)

Full-text search inside type-approval document bodies (PDF text).

    Covers ОТТС / ОТШ / ЗОТТС / ЗОТШ. Other document kinds (СБКТС / ЗОЕТС /
    СУТ / cert / decl) are not covered by full-text search.

    **Premium feature** — requires a plan that includes full-text search
    (see https://hpt.su/pricing/) with a subscription covering at least
    one type-approval kind.

Input parameters:

- `kind`: Filter by registry kind. One of: otts, otch, zotts, zotch. Default: search across all 4 type-approval kinds.
- `page` (integer): 1-based page index.
- `page_size` (integer): Rows per page (max 50).
- `query` (string, required): Free-text query (Russian, tsquery-syntax allowed).

Output parameters:

- `result` (string)

### `list_document_files` (~148 tokens)

List the files attached to a document.

    Returns `[{file_uid, file_name, kind, pages_count, published_at}]` —
    each entry's `file_uid` can be passed to `download_document_file`.

    A document often has several PDFs (e.g. cleaned + original); use this
    tool to enumerate them and pick the right one before download.

Input parameters:

- `document_slug` (string, required): Document slug (from search.slug field).
- `kind` (string, required): One of: otts, otch, zotts, zotch, sbkts, zoets, sout, cert, decl. Slug isn't globally unique between kinds, so kind is required.

Output parameters:

- `result` (string)

### `download_document_file` (~166 tokens)

Get links for a document file: page URL for everyone, direct
    download URL when the plan allows it.

    Always returns `document_page_url` — the document's page on hpt.su
    where the user can download the file manually under their account.
    Share this link with the user.

    When the plan includes direct downloads, the response also contains
    `download_url` — a personal link to the PDF (works only when signed
    in to hpt.su under the same account that owns the API key; the
    download quota is charged at actual download time). Otherwise
    `download_url` is null and `download_note` explains why.

Input parameters:

- `file_uid` (string, required): DocumentFile UID (from list_document_files).

Output parameters:

- `result` (string)

### `list_brands` (~70 tokens)

- `page_size` (integer): Rows per page (max 50).

Output parameters:

- `result` (string)

### `list_vehicle_models` (~76 tokens)

TN VED EAEU classifier lookup.

    Note: TN VED codes are linked **only** to certificates and declarations —
    not to vehicle type approvals or safety reports.

Input parameters:

- `page` (integer): 1-based page index.
- `page_size` (integer): Rows per page (max 50).
- `prefix`: TN VED code prefix (e.g. '8704').
