Give your AI agent the power to book the hard meetings.
WonderCal finds the time across Google, Microsoft, and Apple calendars, coordinates people inside and outside your company, and sends the invite.
Your agent has your calendar. It doesn't have anyone else's.
Every calendar connector can answer ‘what's on today?’ It falls apart when your user says ‘book a call with the client's team next week.’ Now the agent needs availability from people it cannot see across organizations that do not share calendars.
You can build that path: Google OAuth review, Microsoft Graph, time-zone normalization, recurrence expansion, conflict detection, the booking write, and the reschedule flow. Call it three weeks if nothing goes wrong. Something goes wrong.
Give your agent reach, not another calendar reader.
Cross organization
Reach participants at other companies instead of stopping when your user's own calendar runs out.
Required vs. optional
Book when the people who matter are free and include everyone else when the overlap allows it.
Computed, not generated
Let scheduling logic calculate the windows while your agent handles the conversation around them.
One MCP handoff in. A booked hard meeting out.
Your system sends the brief
After OAuth authorization, pass the participants, duration, timing, and constraints through MCP.
WonderCal resolves availability
WonderCal checks Google, Microsoft, and Apple calendars for the best overlap. Everyone else sees only busy or free, never event details.
WonderCal handles the gaps
Participants who are not connected can provide availability without forcing your agent to stop at a booking link.
Your system gets the result
WonderCal sends invitations and returns the confirmed meeting state so your agent can continue.
Safe and secure by design.
Built for agents. Simple for everyone else.
Your agent provides the meeting brief. WonderCal handles cross-calendar availability, required and optional people, and the invitations. Participants see only busy or free—never one another's event details.
What people need to know before they hand off a meeting.
How does my AI agent use WonderCal?
Connect WonderCal through MCP, then tell your agent who should attend, how long the meeting should be, and when it should happen. WonderCal handles the calendar coordination and returns the confirmed meeting.
Which AI agents can use WonderCal?
MCP-compatible agents can use WonderCal, including Claude, Codex, Hermes Agent, and OpenClaw. Once connected, each can hand off a scheduling request in plain language.
Which calendars does WonderCal work with?
WonderCal coordinates availability across Google Calendar, Microsoft Outlook, and Apple Calendar—even when one meeting includes people using all three.
Is it safe to use with private calendars?
Yes. WonderCal shares only whether someone is busy or free with other participants. Your event titles, descriptions, attendees, and other calendar details are never shared with anyone else.
Do guests need to create an account?
No. Anyone who has not connected a calendar can share availability through a private link, so your agent can keep the meeting moving without another signup.
Don't build the calendar. Book the meeting.
Connect WonderCal, give your agent the meeting brief, and let it coordinate Google, Microsoft, and Apple calendars without sharing anyone's event details.
