This document provides a comprehensive guide to building a Watsonx.ai Chatbot RAG Server using MCP, integrating ChromaDB for vector indexing, and exposing it via the MCP Python SDK.

The tutorial guides you through creating a Retrieval-Augmented Generation (RAG) server using IBM Watsonx.ai, ChromaDB for vector indexing, and the Model Context Protocol (MCP) Python SDK. The server processes PDF documents and allows clients to query them, leveraging large language models grounded in specific data. The server is designed to be standalone, with a client for making queries. The tutorial also covers integrating the server with Claude Desktop, providing a seamless interface for interaction.

Features

  • Integration with IBM Watsonx.ai for LLM capabilities.
  • Use of ChromaDB for efficient vector indexing and retrieval.
  • Implementation of the Model Context Protocol (MCP) for standardized communication.
  • Ability to process and query PDF documents for specific information.
  • Integration with Claude Desktop for direct interaction.

MCP Tools

  • {'chat_with_manual': 'A tool that answers questions about drone manuals using RAG with Watsonx.ai.'}

Frequently Asked Questions

What is the purpose of the Model Context Protocol (MCP)?

MCP standardizes the interface between applications and LLMs, allowing for separation of context provision, code execution, and user interaction management.

How does the server handle PDF documents?

The server extracts text from PDF documents, chunks the text for efficient processing, and indexes it using ChromaDB for retrieval during queries.

Can the server be integrated with other platforms?

Yes, the server can be integrated with platforms like Claude Desktop, allowing for direct interaction through a chat interface.
