describe_ui tool not working as expected

[ricardo-luzia]

Hi!

I'm testing the UI automation capabilities but I am never able to get a good response from the describe_ui tool. I always get something like the following:

`Accessibility hierarchy retrieved successfully:

[
  {
    "AXFrame" : "{{0, 0}, {0, 0}}",
    "AXUniqueId" : null,
    "frame" : {
      "y" : 0,
      "x" : 0,
      "width" : 0,
      "height" : 0
    },
    "role_description" : "application",
    "AXLabel" : null,
    "content_required" : false,
    "type" : "Application",
    "title" : null,
    "help" : null,
    "custom_actions" : [

    ],
    "AXValue" : null,
    "enabled" : true,
    "role" : "AXApplication",
    "children" : [

    ],
    "subrole" : null,
    "pid" : 51117
  }
]

Any clue what could be happening? Am I messing something?

Thanks for the MCP!

Can you share more about your project? Is it a standard iOS project, Swift UI or UIKit. I’ve not seen this issue before so I don’t believe it’s widespread but it would be good to understand why it’s happening for you.
