What's Wrong?

The Claude in Chrome extension blocks all navigation and interactions with cloud.comfy.org (ComfyUI Cloud - a legitimate AI image generation platform).

Errors encountered:

1. Attempting to navigate: "Navigation to this domain is not allowed"
2. Manually opening the page, adding it to MCP tab group, then attempting screenshot/interaction: "Permission denied for this action on this domain"

This domain appears to be incorrectly classified/blocked by the extension's server-side domain filter.

What Should Happen?

cloud.comfy.org is a legitimate AI image generation platform (ComfyUI Cloud). The extension should allow navigation and interaction with this domain without any restrictions.
