Agentic RAG with Multi-MCP Tools

Agentic Retrieval-Augmented Generation (RAG) system built with LangChain, Chroma, and multi-MCP tools for intelligent email and web scraping integration.

Overview

This project is a sophisticated agentic RAG system that integrates a Chroma vector database with a LangChain agent to enhance the response quality by incorporating historical conversation context and real-time external tool responses. The system is deployed as a Discord bot and is capable of utilizing multiple Modular Communication Protocol (MCP) tools. Two primary MCP tools are integrated:

• Gmail MCP Server: Provides email functionalities such as scheduling, sending, and fetching emails.
• Web Scraping MCP Server (using crawl4ai): Enables dynamic web extraction and content processing.

Features

• Intelligent Retrieval: Uses a Chroma vector database to split and index documents for efficient context retrieval.
• Memory-Enhanced Interaction: Remembers past conversation context for a more coherent dialogue.
• Multi-MCP Integration: Leverages specialized MCP tools to handle tasks like email operations and web scraping.
• Discord Bot Integration: Interacts with users through Discord commands, providing seamless access to the system’s capabilities.
• Dynamic Tool Invocation: Automatically routes requests based on keywords, whether for email management or web content extraction.

Getting Started

Prerequisites

• Python 3.8+
• A Discord account and server for bot deployment
• Environment variables properly set up in a .env file including:
  • DISCORD_TOKEN
  • GOOGLE_API_KEY
  • MISTRAL_API_KEY
  • SMTP_USERNAME and SMTP_PASSWORD (for Gmail MCP)

Installation

1. Clone the repository:

   git clone [https://github.com/yourusername/agentic-rag-mcp.git](https://github.com/MaitreyaM/MCP-compatible-Agentic-discord-bot)
   cd agentic-rag-mcp
   

2. Create a virtual environment and install dependencies:

   python -m venv venv source venv/bin/activate # On Windows use venv\Scripts\activate pip install -r requirements.txt

3. Set up your environment variables: Create a .env file in the project root with the following content:

   DISCORD_TOKEN=your_discord_token_here
   GOOGLE_API_KEY=your_google_api_key_here
   MISTRAL_API_KEY=your_mistral_api_key_here
   SMTP_USERNAME=your_smtp_username_here
   SMTP_PASSWORD=your_smtp_password_here
   

Running the Bot 1. Start the required MCP servers: • For Gmail MCP, ensure it is running on port 8000. • For the Web Scraping MCP (crawl4ai), ensure it is running on port 8001. 2. Run the Discord bot: python power.py 3. Interact with the bot: Use the Discord commands (e.g., !power <your_query> or !email <your_query>) in your Discord server to interact with the system.

Acknowledgments • Built using LangChain • Vector database powered by Chroma • Web scraping using craw4ai. • Email functionalities using gmail smtp and imap functionalities. • MCP server functionalities provided via Fastmcp.
