Its SKILL.md is 1.6 KB long, well organised into 10 sections with 2 code examples: moderately detailed.
It has no GitHub stars yet, so there is no community track record; judge it on its content.
Maintenance, license and trust
- The repository was last updated about 9 months ago. That is recent enough to be usable, but agent tooling moves fast, so check the instructions against your agent's current version.
- Our last check on 2026-10-19 found the source still online.
- No license is declared. By default that means all rights are reserved: you can read it, but reusing or redistributing it is not clearly permitted. Ask the author before building on it commercially.
- Its trust signals score 74/100, with 3 cautions from licensing, adoption, age or documentation. These come from repository metadata, not a code audit — read the skill file before letting an agent act on it.

行政オープンデータスキル
日本政府のオープンデータに MCP サーバー（mcp.n-3.ai）経由でアクセスする。
データソース
| # | 名前 | 用途 | ツール |
|---|------|------|--------|
| 1 | 不動産取引価格 | 国交省の実取引データ | reinfolib-real-estate-price, reinfolib-city-list |
| 2 | 官公需（入札） | 政府・自治体の調達案件検索 | kkj-search |
| 3 | e-Stat | 政府統計ポータル | e-stat-get-stats-list, e-stat-get-meta-info, e-stat-get-data-catalog |
呼び出し方法
exec で curl を使う。web_fetch は SSE 非対応のため不可。
スクリプト scripts/mcp-call.sh を使う:
bash <skill_dir>/scripts/mcp-call.sh <data_source> <tool_name> '<arguments_json>'
例
# 不動産: 大阪市の取引価格
bash scripts/mcp-call.sh reinfo reinfolib-real-estate-price '{"year":"2025","quarter":"3","area":"27","city":"27102"}'
# 不動産: 市区町村一覧を取得
bash scripts/mcp-call.sh reinfo reinfolib-city-list '{"area":"27"}'
# 官公需: AI関連の入札検索（カテゴリ3=役務）
bash scripts/mcp-call.sh kkj kkj-search '{"query":"AI 人工知能","category":"3"}'
# e-Stat: 統計一覧検索
bash scripts/mcp-call.sh estat e-stat-get-stats-list '{"searchWord":"人口"}'
ツール詳細
各ツールのパラメータ詳細は references/tools.md を参照。
注意点
- 官公需の地域フィルタ:
kkj-searchは都道府県パラメータ未対応。クエリ文字列に地名を含めて絞り込む - 官公需の詳細情報: MCP は検索結果一覧のみ返す。仕様書・金額・締切は元ポータルサイトを確認
- 不動産の都道府県コード: 2桁コード（東京=13, 大阪=27 等）。市区町村コードは
reinfolib-city-listで取得 - e-Stat: まず
get-stats-listで統計IDを特定し、get-meta-infoでメタ情報、get-data-catalogでデータ取得 - レート制限: 公共APIのため常識的な頻度で利用する
