FAQ Bot with Chroma and MCP Tool

Overview

This project implements a FAQ bot that can answer questions from a local set of FAQ markdown files and from an external course metadata service via an MCP‑style HTTP tool.

• Local data – loaded from data/ and persisted in a Chroma vector store.
• MCP tool – HTTP GET request to https://api.example.com/course_meta.
• LLM – Ollama’s llama3 model with nomic-embed-text embeddings.
• CLI – preset questions and interactive mode.
