# OmniTech Customer Support Chatbot

An AI-powered customer support chatbot built with:
- **Gradio** for the web interface
- **MCP (Model Context Protocol)** for tool orchestration
- **ChromaDB** for vector-based document search (RAG)
- **HuggingFace Inference API** for LLM responses

## ⚠️ IMPORTANT: Required Setup

**This Space requires `HF_TOKEN` to be set as a secret, or the LLM won't work!**

Without `HF_TOKEN`, you'll see truncated responses like:
> "Based on our Return policies: OmniTech Solutions Consumer Returns..."

**How to fix:**
1. On the Hugging Face spaces site (huggingface.co/spaces/userid/aia-capstone) click on the **Settings** link in the upper right. 
2. Scroll down until you see the **Variables and secrets** section.
3. Click **New secret** button on right.
4. Fill in the fields with Name: `HF_TOKEN`and Value: Your HuggingFace API token.
5. Click **Save** and the Space will restart automatically
6. You can watch progress back on the **App** tab.

- 🎫 **Ticket creation** - Automatically creates support tickets when needed
