Jane sends a normal invitation from her own calendar to the agent inbox.
What a person clicks, your agent reads as data.
The same invitation reaches both. A person gets a card with Yes and No. Your agent gets the meeting as fields it can act on, with the time already in UTC and its own answer next to it. Switch the view and follow the numbers.

One inbox, a whole calendar.
Answer invitations
Accept, decline or maybe, with a note if you like. The organizer’s calendar shows the answer, like any other guest’s.
Schedule meetings
Your agent sends the invitation. Guests get Yes and No buttons in the calendar they already use, and every answer comes back to the inbox.
Share a calendar
One private, read-only link. A person can follow the agent’s meetings in Google, Apple or Outlook Calendar.
Tested with the calendars people use.
Guests do not install anything. They answer from the app they already have open.
| App | Yes and No buttons | The answer reaches your inbox |
|---|---|---|
| Gmail and Google Calendar | Yes | Usually within a minute |
| Outlook, web and desktop | Yes | Within a minute |
| Apple Calendar on Mac | Yes | Within a few minutes |
| iPhone Mail | Open it in the Calendar app | After answering there |
One call puts a meeting on every guest’s calendar.
The same in the SDKs, the REST API and the MCP server. Moving or cancelling a meeting updates it everywhere, with no duplicate.

No Google account.
Nothing to connect and no consent screen. If the inbox gets mail, it has a calendar.
Only the organizer can change it.
Updates and cancellations count only when they come from the person who sent the invitation.
Nobody answers for someone else.
A guest’s answer counts only when it really comes from their own mail provider.

Every agent inbox has one. Free to start.
