Implementation Reference
- src/gis_mcp/shapely_functions.py:421-434 (handler)The handler function for the 'get_area' MCP tool. It takes a WKT geometry string, loads it with shapely.wkt.loads, computes the area using geom.area, and returns a dictionary with status, area, and message. Errors are logged and raised.
@gis_mcp.tool() def get_area(geometry: str) -> Dict[str, Any]: """Get the area of a geometry.""" try: from shapely import wkt geom = wkt.loads(geometry) return { "status": "success", "area": float(geom.area), "message": "Area calculated successfully" } except Exception as e: logger.error(f"Error calculating area: {str(e)}") raise ValueError(f"Failed to calculate area: {str(e)}")
