Description

An AI-powered workflow to automate Google Calendar operations using dynamic parameters and MCP (Model Control Plane) integration. Enables event creation, availability checks, updates, and deletions with timezone-aware scheduling [[1]][[2]][[8]].

Key Features:

  • 📅 Full Calendar CRUD: Create, read, update, and delete events in Google Calendar.
  • ⏰ Availability Checks: Verify time slots using AVALIABILITY_CALENDAR node with timezone support (e.g., America/Sao_Paulo).
  • 🤖 AI-Driven Parameters: Use $fromAI() to inject dynamic values like Start_Time, End_Time, and Description [[3]][[4]].
  • 🔗 MCP Integration: Connects to an MCP server for centralized AI agent control [[5]][[6]].

Use Cases

  1. Automated Scheduling: Book appointments based on AI-recommended time slots.
  2. Meeting Coordination: Sync calendar events with CRM/task management systems.
  3. Resource Management: Check room/equipment availability before event creation.

Instructions

1. Import Template

  • Go to n8n > Templates > Import from File and upload this workflow.

2. Configure Credentials

  • Add Google Calendar OAuth2 credentials under Settings > Credentials.
  • Ensure the calendar ID matches your target (e.g., ODONTOLOGIA group calendar).

3. Set Up Dynamic Parameters

  • Use $fromAI('Parameter_Name') in nodes like CREATE_CALENDAR to inject AI-generated values (e.g., event descriptions).

4. Activate & Test

  • Enable the workflow and send test requests to the webhook path /mcp/:tool/calendar.
