Keeper.sh
Keeper.sh copies events between Google Calendar, Outlook, iCloud, Fastmail, and other calendar feeds so a booking in one calendar blocks time in the others. It minimizes shared event details and supports Claude or other MCP clients for calendar management; the code can also run on a user's own server.
