Server behavior and tool contracts may change. Tool availability depends on the server configuration.

Kill (close) a tmux window. Requires exact window\_id (e.g. ‘@3’).

Destroys the window and all its panes. Use [kill\_pane](https://libtmux.org/en/py/latest/mcp/tools/kill_pane/) to remove a single pane instead. Self-kill protection prevents killing the window containing this MCP process.
