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 connection provides 10 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.
Coordinating schedules used to feel like an administrative nightmare.
Right now, setting up a simple meeting requires clicking into five different online portals. You copy the details from one site and paste them into another, making sure you don't miss time zones or who needs to be invited. If one person is out of office on Outlook but available on Google, you waste fifteen minutes figuring out where to look.
With this MCP, that friction disappears. Your agent reads your intent—saying 'Let's meet next week.' It automatically checks every connected calendar source and handles the cross-platform coordination in a single conversational turn. You just get the answer.
Fantastical makes managing appointments simple.
You no longer need to manually list out your available slots or worry about which link to share. The MCP automatically manages and updates all your scheduling openings, allowing you to just send one booking link that always points to real-time availability.
It's not just about adding events; it's about maintaining a fluid, single source of truth for every commitment across your entire digital life.
What your AI can actually do with this
You connect Fantastical to any AI agent to take full control of your work schedule and calendar details. Instead of opening five different apps just to check availability, you talk to your agent, which handles the complexity across all your providers. It parses natural language so you can just say 'Schedule a follow-up with Sarah next week' and it figures out the time zone, the people, and the event details automatically.
You get a single view of everything—your events, your tasks, even your available booking slots. This makes coordination easy. Through Vinkius, you connect once from any MCP-compatible client to manage all this data without ever leaving your chat window.
019d7596-7752-70f3-b7e7-c2d2481aeae4 Here's how it actually works
The bottom line is, you get centralized calendar control without manually opening or switching between any of your individual service apps.
Subscribe to the Fantastical MCP, then enter your specific API key into your AI client.
Tell your agent what you need. For example: 'I need to book a deep work session next Tuesday afternoon.'
The agent sends the request via your MCP connection and returns confirmation that the event was successfully created across all linked calendars.
Who is this actually for?
This MCP is for anyone whose job involves coordinating multiple people across disparate digital calendars. If you're tired of toggling between Google Calendar, Outlook, and Apple Reminders just to find an open slot, this is for you.
Coordinating meeting proposals and managing booking availability across several team members using only conversational commands.
Keeping track of project deadlines, recurring meetings, and ensuring all team calendars are accurate without manual data entry or cross-referencing multiple platforms.
Providing clients with up-to-date booking links and handling scheduling conflicts instantly to keep the sales pipeline moving.
What Changes When You Connect
Stop manually checking multiple apps. You can now use natural language to create events, letting your agent handle the time zone and formatting for every connected calendar.
Coordinate complex meetings by asking your agent to list proposals. It tracks suggested times and replies until a final slot is confirmed, eliminating back-and-forth email chains.
Manage booking links effortlessly. Use the list_openings tool to see all active scheduling pages, making it simple to give clients a link they can use immediately.
Keep your tasks synced with appointments by using the reminder tools. You can set up recurring task items right alongside your scheduled meetings, keeping everything in one place.
Maintain data integrity when things change. If a meeting location changes, you just tell your agent to update the event, and it pushes the change across every service like Google or Exchange.
Get a single source of truth. The MCP unifies all calendars—Google, iCloud, etc.—allowing you to view everything in one structural list, making auditing simple.
See it in action
Coordinating an internal team meeting
A PM needs to schedule a 'Q3 Review' with three department heads. Instead of logging into each person's calendar and comparing availability, they just ask their agent to suggest times. The agent uses list_proposals and handles the coordination until everyone accepts the final time.
Handling a new client booking
A Sales Rep gets an inquiry for a strategy session. Instead of sending a manual link, they ask their agent to list all active Openings. The agent provides the correct link and confirms the 60-minute slot is available right now.
Updating travel details mid-trip
A user's flight changes, forcing a meeting update. They tell their agent: 'Change my London appointment to Thursday at 1 PM.' The agent uses the update_event tool and pushes the new time across all linked calendars.
Quickly reviewing the week's commitments
A manager logs in and needs an overview. They ask their agent to list events for the current week. The agent uses list_events and presents a unified, color-coded view of every commitment across all linked services.
The honest tradeoffs
Manual calendar checking
Having to open Google Calendar, then Outlook, then iCloud to see if three different people are free next Tuesday.
Just ask your agent directly. It uses the MCP's unified view to cross-reference availability and suggests a time instantly.
Missing event details
Creating an event but forgetting to add the location or attendees, leading to follow-up emails.
Use natural language commands like 'Schedule lunch with Bob tomorrow at noon' using create_event. The tool handles all the missing context automatically.
Outdated information
Viewing an event that was canceled on one calendar but hasn't updated on another service.
The agent maintains a single source of truth. Use list_calendars to confirm all providers are connected and actively managed.
When It Fits, When It Doesn't
Use this MCP if your primary pain point is the manual, repetitive coordination across multiple scheduling platforms (Google, Exchange, etc.). If you frequently need to propose times or check availability for a group of people, this is essential. Don't use it if you simply need to manage local tasks; stick to dedicated task managers and use create_reminder only when those tasks must be linked to your calendar view.
Questions you might have
How do I use the create_event tool with different time zones? +
You don't have to. Just state the meeting details naturally, like 'Meet next Friday at 2 PM.' The MCP uses Fantastical's advanced parsing engine to correctly interpret and schedule that event across all your linked time zones.
Can I list_calendars to see what services are connected? +
Yes. Using list_calendars confirms which providers (Google, iCloud, etc.) are currently unified under the MCP, letting you audit your connection status at a glance.
What is the difference between list_events and list_openings? +
There's a big difference. list_events shows fixed appointments on specific dates. list_openings shows your customizable booking links, which are designed for people to schedule time with you.
How do I update an event if the location changes? +
Just tell your agent what changed: 'Update my Tuesday meeting. The location is now the new HQ address.' The update_event tool handles pushing that correction to every calendar provider.
What specific details does running list_proposals give me regarding attendee responses? +
It returns proposal titles, suggested times, individual responses, and which slots were finalized. You get a full status of the meeting negotiation without having to check multiple email threads.
If I use create_event for a time that conflicts with an existing booking, what happens? +
The MCP detects scheduling conflicts and alerts you instantly. Your agent can then suggest alternative times or help you modify the event to fit around your current commitments.
When I use create_reminder, how does it handle syncing between Todoist and Apple Reminders? +
It ensures consistency by creating the reminder in both linked services. This guarantees that the task is visible across all platforms you've connected to via Fantastical.
If I run get_event, does it pull details from only one calendar or multiple providers? +
It pulls event data from all your connected providers and presents them in a single view. You see the full picture of any scheduled item regardless of which account owns the booking.
Can my agent create events using natural language phrases like in the Fantastical app? +
Yes. Use the 'create_event' tool. Fantastical's engine is designed to parse phrases like 'Lunch with Bob at 1pm next Tuesday'. The agent will transmit the string and return the structured event data flawlessly.
How do I see my available scheduling links (Openings) via chat? +
Use the 'list_openings' tool. Your agent will retrieve all your active scheduling pages, providing the booking link URLs and duration settings so you can share them with others easily.
Can I suggest multiple meeting times to someone through the agent? +
Absolutely. Use the 'list_proposals' tool to monitor existing suggestions. Fantastical Proposals allow you to offer several slots to attendees, and your agent can help you track their responses and finalize the event.
