Implementation Reference
- src/gis_mcp/pyproj_functions.py:86-107 (handler)The primary handler function for the 'get_crs_info' tool. It takes a CRS identifier as input and returns detailed information about the CRS using the pyproj library, including name, type, axis info, geographic/projected status, datum, ellipsoid, prime meridian, and area of use.
