Japan Data MCP

Overview

Japan Data MCP is a Model Context Protocol (MCP) server: 30 tools for Japanese data: address, furigana, transit, Diet, holidays, weather, corporate registry. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.

It runs locally: the npm package @mameta/japan-data-mcp speaks MCP over stdio on your machine. The current release is v1.1.0, published under the Apache-2.0 license, with source at Mameta29/japan-data-mcp on GitHub.

You'll find Japan Data MCP in the AI & Agents category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
