One API call. We handle multi-party negotiation, external coordination, follow-ups, conflict resolution, and booking. MCP server plus REST API.
They can talk about scheduling but can't actually do it. Building a real scheduling engine takes 6 months minimum and 70+ edge cases. Raw calendar APIs give you events, not coordination. Most agent teams give up and ship a Calendly link.
Claude, GPT, Gemini, and the agent runtimes built on them don't want to write a calendar state machine. They want to call schedule_meeting and get a result. That's what the ANCI MCP server is. Let the AI be the brain. Let ANCI be the hands.
The MCP server is a thin wrapper around the production scheduling engine that has served 128 enterprises since 2020. Not a prototype.
Full scheduling state machine from intent parsing to calendar event creation.
Coordinates with external participants via email. They reply, we book. No accounts required.
24h, 48h, 72h automated follow-ups with host approval gates.
Detects calendar conflicts across all attendees and proposes alternatives automatically.
Full read/write integration with Google Calendar and Microsoft Graph.
Respects each participant's timezone and working hours settings.
Schedule multiple 1:1s in one request. Interview panels, team round-robins.
Made a mistake? Undo any scheduling action within 15 minutes. Full rollback.
Async events: meeting booked, external replied, follow-up sent, action failed.
Every tool your agent needs to schedule, reschedule, cancel, negotiate, and coordinate meetings.
schedule_meetingSchedule a meeting with one or more attendees. Handles internal calendar checks, conflict resolution, and external attendee coordination.
negotiate_with_externalCoordinates scheduling with external participants via email. No account or software install required on their end.
find_availabilityFind available slots for one or more people across calendar systems. Supports constraints and working hours.
reschedule_meetingReschedule an existing meeting. Finds it, checks new availability, notifies all attendees.
cancel_meetingCancel a meeting and notify all attendees with optional reason.
check_conflictsCheck if a proposed time conflicts with any attendee's calendar. Returns alternatives.
schedule_panelSchedule sequential meetings (interview panels, back-to-back sessions with different people).

undo_last_actionUndo any scheduling action within the 15-minute window. Full rollback.
Building a copilot? Add scheduling powers with one integration.
Internal tools that need to book across organizations.
"Schedule a follow-up" is the most-requested AI feature in your roadmap.
