Implementation Reference
- src/gis_mcp/shapely_functions.py:237-251 (handler)The main handler function for the 'get_centroid' tool. It takes a WKT string representing a geometry, uses Shapely to compute its centroid, and returns the centroid geometry as WKT in a structured response dictionary. Errors are logged and raised.@gis_mcp.tool() def get_centroid(geometry: str) -> Dict[str, Any]: """Get the centroid of a geometry.""" try: from shapely import wkt geom = wkt.loads(geometry) result = geom.centroid return { "status": "success", "geometry": result.wkt, "message": "Centroid calculated successfully" } except Exception as e: logger.error(f"Error calculating centroid: {str(e)}") raise ValueError(f"Failed to calculate centroid: {str(e)}")
