## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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 2026-09-20.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs setuptools.build_meta at install time, a recognised native-build step with no shell scripting around it.
  - 0 of 31 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 32/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - License check failed: no license is declared.
  - Actively maintained (last published 5 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 72/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 2303 tokens (~127/item across 18 items; 18 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability check failed: the tool surface changed between 0.2.0 and 0.3.0: 1 tool removals, 0 breaking changes, 5 additions.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 95/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 4 of 5 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "crpt_call_method" implies "execute" and declares readOnlyHint instead, contradicting what its own name says it does.
  - An AI judge read all 18 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.

### 2026-09-11 (score 36)

First indexed and scored.

## MCP tools (18)

### `crpt_check_auth` (~55 tokens)

Check whether the required credentials are present in the environment.

Does NOT reveal secret values — only reports which variables are set.
Returns JSON: {"ready": bool, "missing": [str], "required": [str]}.

Output parameters:

- `result` (string)

List API sections and how many catalog endpoints each contains.

Output parameters:

- `result` (string)

### `crpt_get_section` (~60 tokens)

List all endpoints in one section.

Args:
    section: section name (see crpt_list_sections), e.g. "statistics".
Returns JSON list of {operation_id, method, path, safety, summary}.

Input parameters:

- `section` (string, required)

Output parameters:

- `result` (string)

### `crpt_search_methods` (~79 tokens)

### `crpt_map` (~82 tokens)

The big picture: business entities this API covers and the go-to
methods for each. Call with no args to see the whole map ("you are
here"); pass entity="reviews" (or stocks/prices/orders/…) to list every
method of one entity. Use this before guessing — it orients you fast.

Input parameters:

- `entity` (string)

- `result` (string)

### `crpt_describe_method` (~50 tokens)

Return the full catalog record for one endpoint: method, host, path,

Input parameters:

- `operation_id` (string, required)

Output parameters:

- `result` (string)

### `crpt_call_method` (~180 tokens)

Args:
    operation_id: id from the catalog (see crpt_search_methods).
    path_values: values for {placeholders} in the path.

operations live in crpt_delete_method, reads in crpt_call_method.

Execute one DESTRUCTIVE endpoint: deletes or irreversibly changes data.

Target API: ГИС МТ и СУЗ «Честный знак» (markirovka.crpt.ru, suzgrid.crpt.ru).

Both confirm_write=true and i_understand_this_modifies_data=true are

styles. The array path is taken from the catalog automatically.

Args:
    operation_id: a read endpoint from the catalog.

Secret values are never returned.

Output parameters:

- `result` (string)

### `crpt_add_cabinet` (~219 tokens)

Add or update a cabinet (a named set of API credentials), from chat.

⚠️ This puts the key into the chat transcript — requires
i_understand_key_goes_to_chat=true. The terminal-free safe alternative is
the installer (install.py / double-click), where the key never enters chat.

Args:
    credentials: dict with the required fields for this service
        ({fields}). For Ozon: {{"client_id": "...", "api_key": "..."}};
        for WB: {{"token": "..."}}.
    name: optional label. If omitted, the cabinet is named after the real
        shop name fetched from the marketplace (falls back to "main").
    i_understand_key_goes_to_chat: must be true to proceed.
Saved to ~/.marketplace-mcp/cabinets.json (local, chmod 600), never echoed.

Input parameters:

- `credentials` (object, required)
- `i_understand_key_goes_to_chat` (boolean)
- `name` (string)

Output parameters:

- `result` (string)

### `crpt_set_key` (~222 tokens)

Change / rotate the API key from chat (e.g. the old one expired or
leaked).

⚠️ The key goes into the chat transcript — requires
i_understand_key_goes_to_chat=true. The safe, terminal-free alternative
is the installer, where the key never enters chat. Use a scoped key and
rotate it in the seller cabinet if it was exposed.

Args:
    credentials: dict with the required fields ({fields}).
    cabinet: which cabinet to update. Default: the active one (so "my key
        expired" just works). If there is none, the cabinet is named from
        the marketplace's shop name, else "main".
    i_understand_key_goes_to_chat: must be true to proceed.
On success the key is validated against the marketplace and the shop name
is reported. Saved locally (chmod 600), never echoed back.

Input parameters:

- `cabinet` (string)
- `credentials` (object, required)
- `i_understand_key_goes_to_chat` (boolean)

Output parameters:

- `result` (string)

### `crpt_use_cabinet` (~50 tokens)

Switch the active cabinet. Subsequent API calls use its credentials.

Args:
    name: the cabinet to activate (see crpt_list_cabinets).

Input parameters:

- `name` (string, required)

Output parameters:

- `result` (string)

### `crpt_remove_cabinet` (~43 tokens)

Delete a stored cabinet. If it was active, another becomes active.

Args:
    name: the cabinet to remove.

Input parameters:

- `name` (string, required)

Output parameters:

- `result` (string)
