`pipe_pane`

Log a pane’s live output to a file (or stop an active log).

Streams everything written to the pane (stdout plus terminal control sequences) into a file on disk — the common use is output_path="/tmp/pane.log" to capture scrollback continuously while the agent watches for errors. When output_path is given, starts logging; when output_path is None, stops any active pipe for the pane.

MCP request method: tools/call Send pipe_pane as the tool name, with the arguments below.

Arguments#

append? = true (boolean) #

Whether to append to the file. Default True. If False, overwrites.
output_path? = null (string | null) #

File path to write output to. None stops piping.
pane_id? = null (string | null) #

Pane ID (e.g. ‘%1’).
session_id? = null (string | null) #

Session ID for pane resolution.
session_name? = null (string | null) #

Session name for pane resolution.
socket_name? = null (string | null) #

tmux socket name.
window_id? = null (string | null) #

Window ID for pane resolution.

No other arguments are accepted.
