Ship group scheduling without rebuilding it.
Plug WonderCal's already-built calendar logic into your agent or product. We handle availability, participant coordination, overlap, and booking through MCP or API.
Calendar logic gets hard the moment a third person joins.
One-to-one scheduling is a link. Group scheduling is required and optional participants, Google, Microsoft, and Apple calendars, time zones, reschedules, missing availability, and people outside your company.
You can spend product cycles discovering those edge cases yourself. Or your system can call WonderCal and use the logic we already built to return a confirmed meeting.
Ship sooner. Skip the calendar edge cases.
Use logic that is ready now
Add multi-person scheduling without turning calendar edge cases into a new product roadmap.
Keep your interface and agent
Call WonderCal from your own product while your system keeps the conversation and user relationship.
Grow from one-to-one to real groups
Handle required and optional people across companies, calendar systems, and time zones without a rewrite.
One call in. A confirmed group meeting out.
Your system sends the brief
Pass the participants, duration, timing, and constraints through MCP or the REST API.
WonderCal resolves availability
Our logic checks connected Google Calendar, Microsoft Outlook, and Apple Calendar free/busy data and searches for the best group overlap.
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, returns the confirmed time, and fires webhooks so your workflow can continue.
The scheduling engine behind your product.
The hard group-scheduling logic is already built.
WonderCal exposes 25 MCP tools plus a REST API, OpenAPI specification, API keys, webhooks, and Google, Microsoft, and Apple calendar availability. You plug that logic into your system instead of rebuilding it.
What people need to know before they hand off a meeting.
Do we have to use Claude?
No. Claude and other MCP-compatible agents can use the MCP tools. Custom agents and products can integrate through the REST API and webhooks.
Does WonderCal work when participants use different calendar systems?
Yes. WonderCal is designed to find overlap across Google, Microsoft, and Apple calendars and across company boundaries.
What if a participant has not connected a calendar?
WonderCal can request availability conversationally and combine that response with connected free/busy data.
Can we keep our own interface and agent?
Yes. Your product owns the conversation and user experience. WonderCal runs the scheduling logic behind it.
Do not spend your roadmap rebuilding group scheduling.
Plug in the logic WonderCal already built. Keep your team focused on the product only you can build.
