Implementation Reference

• src/gis_mcp/shapely_functions.py:372-387 (handler)

  The handler function for the 'voronoi' tool. It takes a WKT string of points, computes the Voronoi diagram using shapely.ops.voronoi_diagram, and returns the result as WKT.

  def voronoi(geometry: str) -> Dict[str, Any]:
      """Create a Voronoi diagram from points."""
      try:
          from shapely import wkt
          from shapely.ops import voronoi_diagram
          geom = wkt.loads(geometry)
          result = voronoi_diagram(geom)
          return {
              "status": "success",
              "geometry": result.wkt,
              "message": "Voronoi diagram created successfully"
          }
      except Exception as e:
          logger.error(f"Error creating Voronoi diagram: {str(e)}")
          raise ValueError(f"Failed to create Voronoi diagram: {str(e)}")

• src/gis_mcp/shapely_functions.py:51-59 (registration)

  Resource listing that registers 'voronoi' as an available advanced GIS operation.

  def get_advanced_operations() -> Dict[str, List[str]]:
      """List available advanced operations."""
      return {
          "operations": [
              "triangulate_geometry",
              "voronoi",
              "unary_union_geometries"
          ]
      }
