Implementation Reference
- src/gis_mcp/shapely_functions.py:299-316 (handler)Core handler function for the rotate_geometry tool. Converts input WKT geometry to Shapely object, rotates it using shapely.affinity.rotate, and returns the result as WKT.@gis_mcp.tool() def rotate_geometry(geometry: str, angle: float, origin: str = "center", use_radians: bool = False) -> Dict[str, Any]: """Rotate a geometry.""" try: from shapely import wkt from shapely.affinity import rotate geom = wkt.loads(geometry) result = rotate(geom, angle=angle, origin=origin, use_radians=use_radians) return { "status": "success", "geometry": result.wkt, "message": "Geometry rotated successfully" } except Exception as e: logger.error(f"Error rotating geometry: {str(e)}") raise ValueError(f"Failed to rotate geometry: {str(e)}")
- src/gis_mcp/main.py:66-72 (registration)Imports shapely_functions module, triggering registration of rotate_geometry and other tools via @gis_mcp.tool() decorators.from . import ( geopandas_functions, shapely_functions, rasterio_functions, pyproj_functions, pysal_functions, )
- MCP resource listing rotate_geometry as an available transformation operation.@gis_mcp.resource("gis://operations/transformations") def get_transformations() -> Dict[str, List[str]]: """List available geometric transformations.""" return { "operations": [ "rotate_geometry", "scale_geometry", "translate_geometry" ] }
