You can with python, but you’ll need to be comfortable with the Revit API. Here’s some code for getting the Categories.
Getting the rules is a lot harder and not that easy to code if you don’t know what you’re looking for.

import clr

clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
doc = DocumentManager.Instance.CurrentDBDocument

clr.AddReference("RevitAPI")
import Autodesk
from Autodesk.Revit.DB import *

clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.Elements)
clr.ImportExtensions(Revit.GeometryConversion)

filters = UnwrapElement(IN[0])
categories = []
for filter in filters:
	cat = filter.GetCategories()
	sublist = []
	for c in cat:
		sublist.append(Category.GetCategory(doc,c))
	categories.append(sublist)
#Assign your output to the OUT variable.
OUT = categories
