概要

What is Epsg Mcp Server?

An MCP server that provides specialized knowledge and decision support for Coordinate Reference Systems (CRS) worldwide. It uses a 3-layer fallback: country packs, automatic UTM zone calculation, and safe defaults. Coordinate transformation execution is delegated to another server, so this server focuses on knowledge provision and decision support.

How to use Epsg Mcp Server?

Install via npm: npm install @shuji-bonji/epsg-mcp. Run directly: npx @shuji-bonji/epsg-mcp. Configure in Claude Desktop by adding to claude_desktop_config.json with command npx and args ["@shuji-bonji/epsg-mcp"]. Optionally set environment variables EPSG_PACKS and EPSG_LANG for country packs and language.
