Jarvis: Productivity AI Agent for Tasks, Calendar, Email & Expense using MCPs

Who’s it for

This template is designed for anyone who wants to use Telegram as a personal AI assistant hub.
If you often juggle tasks, emails, calendars, and expenses across multiple tools, this workflow consolidates everything into one seamless AI-powered agent.

What it does

Jarvis listens to your Telegram messages (text or audio) and processes them with OpenAI.
Based on your request, it can:

• ✅ Manage tasks (create, complete, or delete)
• 📅 Handle calendar events (schedule, reschedule, or check availability)
• 📧 Send, draft, or fetch emails with Gmail
• 👥 Retrieve Google Contacts
• 💵 Log and track expenses

All responses are returned directly to Telegram, giving you a unified command center.

How to set up

1. Clone this template into your n8n workspace.
2. Connect your accounts (Telegram, Gmail, Google Calendar, Contacts, etc.).
3. Add your OpenAI API key in the Credentials section.
4. Test by sending a Telegram message like “Create a meeting tomorrow at 3pm” or “Add expense $50 for lunch.” or "Draft a reply with a project proposal to that email from Steve"

Requirements

• n8n instance (cloud or self-hosted)
• Telegram Bot API credentials
• Gmail, Google Calendar, and Google Contacts credentials (optional, if using those features)
• OpenAI API key
• ElevenLabs API Key (optional, if you need audio note support)

How to customize

• Swap Gmail with another email provider by replacing the Gmail MCP node.
• Add additional MCP integrations (e.g., Notion, Slack, CRM tools).
• Adjust memory length to control how much context Jarvis remembers.

With this template, you can transform Telegram into your all-in-one AI assistant, simplifying workflows and saving hours every week.
