japan-geospatial-open-data-mcp
日本全国規模のジオスパティアル・オープンデータを AI エージェントに届ける MCP Server。 GSI 地理院タイル・地理院住所検索・e-Stat 統計 API・国土数値情報(小学校区)・不動産情報ライブラリを 1 つの MCP でまとめて公開する。
Context: FOSS4G Hiroshima 2026 発表「Building an MCP Server Ecosystem on Japan's National-Scale Geospatial Open Data Platform」(Mami Enomoto, MLIT) が示した方向性に追従するエコシステム構築タスク。 Needs: 不動産分析(学区・用途地域)・教育インフラ評価・防災・都市計画。 TOS: GSI/e-Stat/国土数値情報は公式オープンデータ・再利用自由。
Tools (7)
| Tool | Description | Key required |
|---|---|---|
geocode_japan | 住所 → 緯度経度(GSI 住所検索 API, msearch.gsi.go.jp) | No |
get_gsi_tile | 地理院 XYZ タイル(std/pale/blank/aerial/vector)を base64 画像で取得 | No |
list_data_sources | アクセス可能な全データソース一覧と鍵要件 | No |
get_estat_data | e-Stat 統計データ取得(人口・人口動態・世帯 etc.) | ESTAT_APP_ID |
get_estat_meta | e-Stat 統計表メタ情報取得 | ESTAT_APP_ID |
list_school_districts | 全国小学校区 (A27) GML/GeoJSON ファイル一覧(国土数値情報, nlftp.mlit.go.jp) | No |
get_school_district_geojson | 小学校区 GIS タイル (XKT004) GeoJSON 取得(不動産情報ライブラリ) | REINFOLIB_API_KEY |
Environment variables (optional)
ESTAT_APP_ID— e-Stat application ID (free: https://www.e-stat.go.jp/api/)REINFOLIB_API_KEY— MLIT Real Estate Information Library API key (application: https://www.reinfolib.mlit.go.jp/)USER_AGENT— override default User-Agent string
No keys → core GSI + school district listing still works out of the box.

MCP Registry
Publishing to the official MCP Registry is a follow-up task.
The mcp-publisher CLI (GitHub auth, io.github.atushi1841/japan-geospatial-open-data-mcp namespace) is the standard flow.
