Japan Data Mcp

Overview

Japan Data Mcp is a Model Context Protocol (MCP) server: 日本の公的データ（統計・法人・不動産）にAIからアクセスするMCPサーバー。e-Stat統計API・法人番号Web-API・不動産情報ライブラリAPIの3API統合。全国約1,700市区町村対応。. Because it speaks the Model Context Protocol, AI assistants can use Japan Data Mcp as a set of callable tools instead of you copy-pasting between apps.

It runs locally: the Python package japan-data-mcp (via uvx) speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need ESTAT_APP_ID. The current release is v0.1.1, published under the MIT license, with source at Izyuusya/japan-data-mcp on GitHub.

On mcp.site, Japan Data Mcp sits in the Development category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
