Calling tabs_context_mcp with createIfEmpty:true creates a new window, tab group and an empty tab when none exists. If you then also call tabs_create_mcp to work in a fresh tab, the first blank tab remains open too. Track both tab ids and close each with tabs_close_mcp at the end. When the last tab closes, Chrome removes the group automatically, so the next run starts clean.
