Prompt Time

ryanjamesstewart/prompt-time

Windows-native reminder system that uses Task Scheduler and PowerShell toasts instead of running a Node process. Gives Claude three tools: schedule_reminder, list_reminders, and cancel_reminder. Handles the MSIX packaging quirks in Claude Desktop so reminders persist across reboots and survive the virtualized filesystem boundary. The MCP server just writes JSONL; a separate watcher task polls the queue and renders notifications. Zero dependencies, installs with a batch file, supports one-time and recurring schedules at weekday/daily/weekly granularity. Reach for this if you want Claude to manage Windows notifications without npm or keeping a daemon alive yourself.
