Unmeasured means there is not enough evidence to decide. How these checks work

Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 84 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name n.3.ai MCP Server.

  • Pass
    Lists tools

    tools/list returned 3 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 84 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 84 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

    Every tool description is at least 20 characters.

  • Pass

    32 of 32 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Fail
    Repo owner matches

    The GitHub repository owner does not match the namespace login.

  • Fail

Capabilities

Tools 3

e-stat-get-data-catalog

e-Statに登録されている統計データベースのカタログ情報（統計名、説明、提供状況、ファイルのダウンロードURLなど）を取得する。統計データの全体像把握やファイル取得用途に使用する。

Discovered
e-stat-get-meta-info

e-stat-get-stats-list ツールで取得した統計表IDに基づいて、メタ情報（分類項目、地域区分、時間軸、表章事項などの構造情報）を取得する。ここで得た分類ID・項目コードは e-stat-get-stats-data ツールの絞り込み引数（cdCat01, cdArea など）に指定する。

Discovered
e-stat-get-stats-list

指定した条件に基づき、e-Statに登録されている統計表の一覧および基本情報（統計表ID、統計名、調査年月、公開日など）を取得する。実際の統計数値は含まれないため、ここで得た統計表IDを e-stat-get-stats-data ツールに渡して取得する。
