claude-code-ntfy-notification-hook

A Claude Code hook that forwards Notification events to an ntfy.sh topic as push notifications.

Installation

pip install claude-code-ntfy-notification-hook

Usage

Configure Claude Code to call send-ntfy-claude-notification as a hook for Notification events. In your Claude Code settings (.claude/settings.json or ~/.claude/settings.json):

{
  "hooks": {
    "Notification": [
      {
        "matcher": "",
        "hooks": [
          {
            "type": "command",
            "command": "send-ntfy-claude-notification my-ntfy-topic"
          }
        ]
      }
    ]
  }
}

Replace my-ntfy-topic with your ntfy.sh topic name.
