Geojp is a Model Context Protocol (MCP) server: MCP server for Japan geodata: cadastral lot numbers (chiban) and reverse geocoding, for AI agents. In practice that means any MCP-compatible AI assistant can call Geojp's tools directly — the model decides when to use them in a conversation or agent run.
You can run Geojp two ways: connect to the hosted endpoint at https://mcp.reversegeojp.com with no local install, or run it on your own machine via the npm package geojp-mcp. Configuration happens through environment variables — you'll need GEOJP_API_KEY. The current release is v0.1.0, published under the MIT license, with source at 55tarkun/geojp-mcp on GitHub.
Geojp is listed under AI & Agents on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
