Direct calendar scheduling with this MCP Server

This MCP Server lets Cline run `create_event` to block out time for your development tasks. You tell Cline to build a feature, and it reserves a two-hour block on your calendar so nobody schedules a meeting while you write code. It checks your existing schedule first using `list_events`. If you are booked, Cline finds the next empty slot and schedules the work block there, updating you in the sidebar chat.

Manage client bookings while writing code

The `list_openings` tool allows Cline to fetch your active scheduling templates directly from Fantastical using this MCP Server. If you are building a contact page, Cline can pull these openings and embed them directly into your frontend code. It uses `get_opening` to retrieve the exact booking link details. This lets Cline write precise integration tests using real, live scheduling data from your account.

Sync task reminders with your active codebase

The `create_reminder` tool lets Cline turn code comments into actionable tasks. When Cline finds a broken test or a legacy code block, it writes a reminder directly to your Fantastical inbox. These reminders sync to Apple Reminders or Todoist. Cline links the reminder back to the specific file and line number, so you know exactly what needs fixing when the alert pops up.
