mcp-server-proj is an MCP server for cartographic projections and coordinate transformations. It provides tools to transform coordinates between different coordinate systems using EPSG codes, WKT, or Proj formats, and is intended for users working with geospatial data in MCP-compatible clients like Claude Desktop.
Install and run the server using uvx mcp-server-proj (published) or uv pointing to a local copy (development). Configure the server in your MCP client’s JSON configuration file (e.g., Claude Desktop). The server exposes two tools: transform-coordinates and list-supported-crs.
It supports EPSG codes (e.g., EPSG:4326), Well-Known Text (WKT) format, and Proj format.
Edit the `claude_desktop_config.json` file located in `~/Library/Application Support/Claude/` (macOS) or `%APPDATA%/Claude/` (Windows). Use `uvx mcp-server-proj` for published servers or `uv --directory <path> run mcp-server-proj` for development.
Use the MCP Inspector by running `npx @modelcontextprotocol/inspector uv --directory <path> run mcp-server-proj` and opening the provided URL in a browser.
The tool accepts an array of points with x, y values, so it can transform multiple coordinates in a single call.
Visit https://epsg.io/ for EPSG definitions, or the proj4js library repository for JavaScript implementations.
