Implementation Reference
- src/gis_mcp/shapely_functions.py:421-434 (handler)The main handler function for the MCP tool 'get_area'. Decorated with @gis_mcp.tool() for automatic registration. Parses WKT geometry using Shapely and computes its area.@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)}")
- src/gis_mcp/shapely_functions.py:61-70 (registration)Resource endpoint that lists 'get_area' among available measurement operations, aiding in tool discovery.@gis_mcp.resource("gis://operations/measurements") def get_measurements() -> Dict[str, List[str]]: """List available measurement operations.""" return { "operations": [ "get_length", "get_area" ] }
