What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

    const run = t * 9 + k * (drop / 3)

    for await (const piece of $.process.spawn({ argv, input: JSON.stringify(snapshot) })) {

This one needs environment variables set before it will start: HA_URL (Your Home Assistant's address, e.g. http://homeassistant.local:8123 (or use VOMEHOME_TOKEN instead)), HA_TOKEN (A Home Assistant long-lived access token), HA_ALLOW_WRITE (Set to true to allow service calls and edits; reads only without it), VOMEHOME_TOKEN (A key from the Vome app's Agent tab, to reach the home through Vome instead of HA_URL and HA_TOKEN). The author declared them in the registry entry; get the values from the project itself.
