Ask from a terminal, or let your assistant ask.

The macometer command talks to the running app over a local socket and answers with what the app already knows. The same answers are available to AI assistants over MCP. Add --json for scripts.

Sample commands and output.

A short list of real questions.

status, top, app, find, ports, projects, containers, agents, tokens, awake, battery, history, why, can-quit, quit and stop.

It reaches back in time.

top --by memory --at 14:02 and history cpu --period day answer from the same history the window draws.

15 tools over MCP.

get_status, top_apps, find_process, inspect_process, list_ports, list_projects, list_containers, list_agents, get_token_usage, get_battery, get_history, get_insights, what_is_keeping_awake, can_quit and request_quit.

Nothing can skip the confirmation.

quit, stop and request_quit raise the same question in the app and wait. No flag turns that off, for you or for an assistant. A no is a normal answer.

Nothing is edited behind your back.

Installing the command adds one link, from a button in Settings. Macometer never edits an assistant's settings. It gives you the text to paste.

$7.99 for the first 25, then $14.99, once. No subscription.
