How do I connect my existing calendars?

Fantastical unifies your Google, iCloud, and Microsoft 365 accounts. Once you connect the MCP, your agent can see and manage all of them through your Fantastical account.

What do I need to get started?

You will need a Fantastical API Key, which you can find in your Flexibits Account Hub under the Integrations section.

Can I use this with my reminders?

Yes. The MCP can create reminders that sync with Apple Reminders or Todoist depending on your specific setup.

Which AI clients can I use?

You can use this MCP with any compatible client, including Claude, Cursor, Windsurf, and VS Code.

Does it support natural language?

Yes. The core feature is using natural language to create and update events, such as 'Lunch tomorrow at noon'.

Can my agent create events using natural language phrases like in the Fantastical app?

Yes. Use the 'create_event' capability. 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' capability. 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' capability 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.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Automate a task

Put Fantastical to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

Fantastical works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Fantastical to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.
