+# FAQ‑Bot – ChromaDB + MCP Tool
 
-Повторный экзамен: FAQ-бот — ChromaDB + один MCP-tool
+## Overview
+This project implements an FAQ‑bot that answers questions about local course notes stored in Markdown files using **ChromaDB** for retrieval and a single **MCP‑style tool** for metadata queries.
+
+- **Local knowledge** – 2–3 `.md` files in `data/`.
+- **Vector store** – ChromaDB with Ollama embeddings.
+- **Tool** – `fetch_course_meta` that performs a GET request to a local JSON file (mock MCP server).
+- **Agent** – LangGraph agent that routes the query to the appropriate source and labels the answer with `source: chroma | mcp_meta`.
+- **CLI** – 3 example questions (2 for Chroma, 1 for meta) and an interactive mode.
+
+## Setup
+```bash
+# Pull Ollama model
+ollama pull nomic-embed-text
+
+# Install dependencies
+pip install -r requirements.txt
+
+# Start local mock MCP server (JSON file)
+python -m http.server 8000 --directory mock
+```
+
+## Running the Bot
+```bash
+python main.py --question "What is the course schedule?"
+```
+
+## Example Questions
+1. **Chroma** – *"What topics are covered in week 3?"*
+2. **Chroma** – *"How many hours per week are required?"*
+3. **Meta** – *"What is the course schedule?"*
