Google Calendar MCP App

What it does

This MCP App transforms Google Calendar interactions from plain text to rich, interactive visual experiences. It renders real-time calendar views, availability heatmaps, and event forms inline within the AI conversation.

Key features

• Visual Calendars: View schedules via Day, Week, Month, or Agenda grids.
• Availability Heatmap: Quickly visualize free/busy slots across multiple calendars.
• Interactive Event Forms: Create and edit events with date/time pickers and color selection.
• Multi-Account Support: Manage and query multiple Google accounts simultaneously.
• Direct Actions: RSVP to invites and join Google Meet calls directly from the UI.
