No install. No account. Public and anonymous. The link asks your agent for one report, nothing else. What it sends
Session tab group vanishes right after creation, tool calls fail. After tabs_context_mcp returns a tab and tabGroupId, the next call such as navigate or get_page_text says the tab is not in Claude's tab group.
