## 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 2026-08-20.

- **Endpoint Security**: 51/100
  - 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 3 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - 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 (excellent).
  - Context-footprint check failed: tool/resource definitions use about 699 tokens (~233/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**: 40/100
  - Stability observed for 12 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.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (3)

### `search_surveys` (~200 tokens)

アンケート調査を探す

キーワードでアンケート調査を検索します。言い換え（AI／人工知能、リモートワーク／在宅勤務など）でも見つかります。返ってくる survey_id を get_survey に渡すと集計結果を取得できます。

Input parameters:

- `category_id` (integer): list_categories が返した category_id。指定するとその配下（全階層）の調査だけを検索する
- `limit` (integer): 取得件数（既定10、最大30）
- `min_respondents` (integer): 回答者数の下限。引用に耐える標本だけが欲しい場合に指定する
- `query` (string, required): 探したい話題。日本語の自然な言い回しでよい（例: 老後の不安、AI活用、在宅勤務のつらいところ）

### `get_survey` (~151 tokens)

調査の集計結果を取得する

調査1件の設問・選択肢・得票数・割合を取得します。引用用の固定URL（citation.stable_url。固定できる時点が無い調査では null）とライセンスも一緒に返します。

Input parameters:

- `as_of` (string): YYYY-MM 形式。その月末時点までの累計に固定する（引用向け）。省略すると最新の累計
- `survey_id` (integer, required): search_surveys が返した survey_id
- `trusted_only` (boolean): true にすると、メール確認済みアカウントの票だけに絞った集計を返す

### `list_categories` (~79 tokens)

カテゴリ一覧を見る

どんな分野の調査があるかを大分類→中分類→小分類の階層で確認できます。何が調べられるか把握したいときに使います。

Input parameters:

- `parent_id` (integer): 指定するとその配下だけを返す。省略すると大分類の一覧
