Fetch-style servers pull HTML or Markdown. They are cheaper and easier to lock to a host. They fit docs and public pages.
A browser MCP can click, read the console, and keep cookies. It can also see an admin session you already opened.
Try read-only fetch first. If you truly need render or login, open a local browser tool and point it only at your origin.
See local vs remote MCP. Do not hand a production admin console to an unknown browser server.
