-Solution for FAQ bot with ChromaDB and MCP tool
+## Overview
+
+This repository implements a FAQ bot that answers questions about course materials using a local **ChromaDB** vector store and, when needed, a single **MCP-style tool** that fetches course metadata.
+
+## Features
+
+* **ChromaDB** for semantic search over lecture markdown files.
+* **MCP-style tool** (`fetch_course_meta`) that simulates an external MCP service.
+* **LangGraph**‑based agent that routes queries to the appropriate tool and prefixes the answer with the source.
+* CLI with preset questions and an interactive mode.
+
+## Setup
+
+```bash
+# Pull embeddings model
+ollama pull nomic-embed-text
+
+# Install dependencies
+pip install -r requirements.txt
+
+# Run a simple HTTP server to serve meta.json (for the MCP tool)
+# In a separate terminal:
+#   python -m http.server 8000
+```
+
+## Running the Bot
+
+```bash
+python main.py
+```
+
+The script will load the FAQ data, build the ChromaDB index, and then run the demo questions followed by an interactive prompt.

+## Notes
+
+* The MCP tool currently points to `http://localhost:8000/meta.json`. Replace with your actual endpoint if needed.
+* The agent uses `ChatOpenAI` via OpenRouter; set `OPENAI_API_KEY` in your environment.
