What you can do with this MCP connector
Fantastical handles your whole calendar stack. Your agent lets you create, read, and manage events and reminders across Google, iCloud, Exchange, and Microsoft 365—all from a single chat. You'll never have to jump into a separate calendar app again.
create_event lets you schedule new events just by talking to your agent. If you tell it something like, 'Lunch with Bob tomorrow at noon,' it automatically creates the event in Fantastical and adds it to the necessary accounts.
create_reminder makes new tasks or reminders that sync up with Apple Reminders or Todoist. delete_event permanently removes an existing event from Fantastical. get_event pulls all the details for one specific event using its unique ID. list_calendars shows you all the calendar accounts connected to Fantastical, telling you their status and color coding.
Need to know what's on the books? list_events lists all calendar events for a date range you specify. update_event lets your agent modify an existing event—it handles the title, time, location, or notes across all connected calendars. You'll never have to worry about keeping your schedule consistent across multiple services again.
Managing time slots is simple. list_openings retrieves a list of all your active scheduling pages or booking links, and get_opening gets specific details about one of those booking openings. list_proposals summarizes all meeting proposals, showing suggested times and who's responded to get a final slot confirmed. list_openings also lets you see your current availability to meet.
That's it. You've got your whole schedule view in one place, and your agent acts on your behalf.
How Fantastical MCP Works
- 1 Subscribe to this server and provide your Fantastical API Key (find it in your Flexibits Account Hub).
- 2 Start the conversation in your preferred AI client (Claude, Cursor, etc.) and ask your agent to perform a scheduling action.
- 3 Your agent calls the necessary tools, gathers the data from all connected calendars, and presents the final, confirmed schedule details in the chat.
The bottom line is, you tell your agent what you need done, and it handles the connection, data retrieval, and writing to all your calendar services.
Who Is Fantastical MCP For?
Anyone who deals with more than one calendar app is going to love this. It's for the busy professional who hates switching between Google Calendar, Outlook, and Apple Calendar just to book a meeting. It’s for the executive assistant who needs to manage 10 different people’s schedules without ever leaving their chat window.
Manages proposals and booking openings for teams. They use the agent to check multiple calendars, suggest three times, and finalize the booking without manual email chains.
Needs to audit the unified schedule across multiple team members' accounts. They ask the agent to list all events for the week to spot conflicts or gaps.
Needs to provide quick booking links to clients. They ask the agent to list open slots so they can send a direct booking link.
What Changes When You Connect
- Audit your entire schedule instantly. Instead of opening five different calendar apps, your agent uses
list_eventsto pull every event across Google, iCloud, Exchange, and M365 into one view. - Book meetings without back-and-forth. Use
list_proposalsto suggest multiple times to attendees and track replies until the meeting is finalized, saving hours of email ping-pong. - Always look available. Use
list_openingsto check and manage your shareable booking links. You can let people book time with you without you ever having to give them a direct link. - Keep tasks synced. Don't use a separate to-do list.
create_reminderhandles task-like items and syncs them to Todoist or Apple Reminders alongside your actual calendar entries. - Fix event details fast. If a meeting moves, don't manually update it everywhere. Use
update_eventto change the title, time, or location across every provider simultaneously. - Build events from plain text. Use
create_eventto tell your agent, 'Coffee with John tomorrow at 2 PM.' It handles the date parsing and creation across all accounts automatically.
Real-World Use Cases
The Quarterly Review Coordination
The Project Manager needs to schedule a review with five people across three time zones. They ask the agent to check availability. The agent runs list_calendars first, then uses list_openings to check common availability, and finally uses list_proposals to suggest three optimal slots, solving the coordination mess in one go.
The Out-of-Office Scheduler
The Sales Rep is going on vacation and needs to set up availability. They tell the agent to check their status. The agent runs list_openings to list their active booking links and ensures all calendar providers are correctly linked via list_calendars.
The Quick Follow-Up Meeting
A team member needs to schedule a quick 30-minute follow-up call with a client. They prompt the agent with, 'Book a quick call with Sarah tomorrow morning.' The agent uses create_event to parse the intent and adds the event to the correct calendar.
The Historical Audit
The Operations Lead needs to see everything that happened last month. They ask the agent to list all events for the last 30 days. The agent executes list_events using the date range, providing a unified view of the past month's activities.
The Tradeoffs
Juggling multiple calendar apps
Opening Google Calendar, logging into Outlook, switching to iCloud, and manually copying and pasting event details just to see if everyone is free.
→
Ask your agent to check availability. It uses list_calendars to unify the view, then runs list_proposals to suggest slots and confirm the booking in one go.
Forgetting to update event details
A meeting location changes, so the user manually updates it in Google Calendar but forgets to change it in Outlook.
→
Use update_event to change the location or title. This tool ensures the modification syncs across all connected calendar providers simultaneously.
Using a separate to-do app for tasks
Creating a reminder in Todoist and then manually entering the same date and time into Outlook just so it shows up with the meeting.
→
Use create_reminder. This tool handles task-like items and ensures they sync with the calendar ecosystem, keeping your to-do list and schedule aligned.
When It Fits, When It Doesn't
Use this if you need to coordinate schedules across different platforms (Google, Apple, Microsoft) or if you need to book meetings without sending multiple emails. It's best for complex, multi-party coordination. Don't use this if you just need to check one calendar source—you'll use a simpler single-service API. If your primary need is just simple data retrieval without any write capabilities, check the list_events tool first, as it's read-only. But if you need to schedule, this is the right choice.

Works with Claude, ChatGPT, Cursor, and more
The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.
This server provides 10 capabilities that interface natively with Claude, ChatGPT, Cursor, and any MCP client. No middleware. No custom integration required.
Available Capabilities
Coordinating a schedule shouldn't feel like logging into five different apps.
Today, scheduling means clicking through tabs. You check Google Calendar for morning availability, then switch to Outlook to check with the finance team. If that's clear, you open Apple Calendar to check with your boss. Then, you copy the details and paste them into a separate tool to create the event.
With this MCP server, you just tell your agent the goal: 'Schedule a review with John, Sarah, and me next Tuesday.' The agent runs `list_calendars` to see what's connected, and then uses `list_proposals` to suggest three slots that work for everyone, all from the chat.
Fantastical MCP Server: Schedule events from plain text.
Manual event creation requires specific formatting: 'Event Title' must go in one field, 'Start Time' in another, and 'End Time' in a third. This is tedious and easy to mess up.
Now, just ask your agent: 'Schedule a follow-up call with the client tomorrow afternoon.' The agent uses `create_event` to parse the natural language, figuring out the time, title, and necessary accounts without you having to structure a single field.

Yes. The tool modifies an event and transmits the change synchronously across every underlying calendar provider, ensuring your schedule stays consistent everywhere.
Can I set up recurring tasks using `create_reminder`? +
