# tool si.act.notification_channel

Writes one notification channel, which is where a notice goes: The channel is ready once its test notice is acknowledged.

[figure: Over MCP, si.act.notification_channel takes NotificationChannelInput and returns a card whose body is NotificationChannel.]

The channel is ready once its test notice is acknowledged. Until then it is not ready, with the reason. The call needs the act grant at the user rung.
