Simple scheduling and internal document query bot with Telegram

Template Overview This workflow demonstrates how to build a simple Telegram bot that can schedule events, check service prices, and query company documents using AI integrated with MCP and RAG. It’s designed to show how n8n can connect conversational interfaces with internal tools in a clear and scalable way.

Key Concepts (explained simply):

MCP (Multi‑Channel Processing): A framework that lets the AI agent connect to external services (like Google Calendar, Docs, Sheets) through MCP Clients and Servers. Think of it as the “bridge” between the bot and your tools.

RAG (Retrieval‑Augmented Generation): A method where the AI retrieves information from documents before generating a response. This ensures answers are accurate and based on your actual data, not just the AI’s memory.
