Command line

The mightty binary inside the app is also the command-line tool. Install explains how to put it on your PATH.

Open a window

mightty [--SETTING=VALUE...] [-e PROGRAM [ARGS...]]

Opens a window. With -e, the window runs that program in the current folder and closes when the program exits. Any setting can be given as a flag; see Settings.

Edit settings

mightty config [--export]

Opens the settings screen in the terminal you are in. With --export, it prints every setting and action as JSON instead.

Control a running Mightty

mightty ctl COMMAND

Controls panes in a running Mightty: running commands, pressing keys, reading output, changing focus and watching events. See Agents and scripting.

Serve MCP

mightty mcp [--all-panes]

Runs an MCP server for AI agents on standard input and output. See Agents and scripting.

Run a program without a window

mightty run [--cols N] [--rows N] [--screen] -- PROGRAM [ARGS...]

Runs a program in a terminal with no window, then prints what the program displayed: its scrollback and screen, or the screen only with --screen. The terminal is 80×24 unless you set --cols and --rows. mightty run exits with the program's exit code, which makes it useful in tests.
