CalendarPipe gives agents their own real calendars

CalendarPipe launched on Product Hunt today. On the surface it's a programmable calendar sync — filter, transform, route events across Google/Outlook/Apple through customizable pipes. But the agent angle is where it gets interesting.

It ships REST API, CalDAV, and an MCP server. Agents can spin up their own hosted calendar and send real email invites to real humans — no OAuth dance required. That's a small fix with a big blast radius: scheduling is still one of the most unsolved pieces of the 'AI chief of staff' category because nobody wants to hand an LLM their Google OAuth token.

Founders Jakub Beneš and Tomas Ruzicka built it on Vercel/Linear/Supabase. The framing I like: calendars are the last shared human protocol, and making them programmable for agents is table stakes for any assistant that actually schedules things.
