`get_window_info`

Return metadata for a single tmux window (ID, name, layout, dimensions).

Use this instead of list_windows + filter when you only need one window’s info. Resolves the window by window_id first; falls back to window_index within a session if window_id is not given.

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

Arguments#

session_id? = null (string | null) #

Session ID for window_index lookup.
session_name? = null (string | null) #

Session name for window_index lookup.
socket_name? = null (string | null) #

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

Window ID (e.g. ‘@1’).
window_index? = null (string | null) #

Window index within the session. Requires session_name or session_id to disambiguate.

No other arguments are accepted.

Result#

Returns object

active_pane_id? = null (string | null) #

Pane id (%N) of the window’s active pane.
pane_count (integer) #

Number of panes
session_id? = null (string | null) #

Parent session ID
session_name? = null (string | null) #

Parent session name
window_active? = null (string | null) #

Active flag (‘1’ or ‘0’)
window_height? = null (string | null) #

Height in rows
window_id (string) #

Window ID (e.g. ‘@1’)
window_index? = null (string | null) #

Window index
window_layout? = null (string | null) #

Layout string
window_name? = null (string | null) #

Window name
window_width? = null (string | null) #

Width in columns
