Implementation Reference

• src/gis_mcp/shapely_functions.py:283-296 (handler)

  The handler function decorated with @gis_mcp.tool() that implements the get_geometry_type tool. It takes a WKT geometry string, loads it with Shapely, and returns the geometry type (e.g., 'Point', 'LineString') along with status and message.

  @gis_mcp.tool()
  def get_geometry_type(geometry: str) -> Dict[str, Any]:
      """Get the type of a geometry."""
      try:
          from shapely import wkt
          geom = wkt.loads(geometry)
          return {
              "status": "success",
              "type": geom.geom_type,
              "message": "Geometry type retrieved successfully"
          }
      except Exception as e:
          logger.error(f"Error getting geometry type: {str(e)}")
          raise ValueError(f"Failed to get geometry type: {str(e)}")
