Build Your Own AI Personal Assistant: Automating Calendars with n8n and MCP

Описание и применение

Создайте AI‑ассистента, который проверяет свободное время и бронирует встречи, используя n8n для работы с API календаря и MCP для безопасного доступа к данным.

Задача

Users want an AI that can check free slots and book meetings without manual UI navigation, while keeping calendar credentials secure.

Результат

The setup allows secure, automated calendar management via an AI agent, with visual debugging and easy extensibility.

Рабочий процесс

• Create n8n workflow with listEvents and createEvent nodes and expose via Webhook.
• Build an MCP server that proxies requests to the n8n webhook and defines a tool (n8n_calendar_query).
• Configure the AI desktop client to use the MCP server.
• Interact: User asks AI to check availability and book a session; AI calls n8n_calendar_query with action "list"; n8n returns free slots; AI selects slot and calls action "book"; n8n updates calendar.

Доказательства

Your calendar credentials live inside your self-hosted n8n instance, not in an AI vendor's cloud.

Источник

Use n8n's visual execution history to see exactly why an agent failed to book a meeting.
