The **AI Digital Library Assistant** is a next-generation knowledge management tool built for the **MCP 1st Birthday Hackathon**. It transforms your static document collection into an interactive, living library.

Unlike traditional RAG (Retrieval Augmented Generation) apps, this project leverages the **Model Context Protocol (MCP)** to create a modular ecosystem of tools—Ingestion, Search, and Podcast Generation—that work harmoniously to help you consume information in the way that suits *you* best.

## 🚀 Quick Start

Check out [QUICKSTART.md](QUICKSTART.md) for detailed local setup instructions.

1.  **Clone & Install**:
    ```bash
    git clone https://huggingface.co/spaces/Nihal2000/AiDigitalLibraryAssistant
    pip install -r requirements.txt
    ```
2.  **Configure**: Add your `OPENAI_API_KEY` and `ELEVENLABS_API_KEY` to `.env`.
3.  **Run**: `python app.py`

## 💡 How It Works

### 1. The MCP Core
At the heart of the application is the `AiDigitalLibraryAssistant`. It exposes atomic capabilities (Tools) that the frontend consumes. This means the same tools powering this UI could be connected to Claude Desktop or any other MCP client!
    
    ```bash
    {
      "mcpServers": {
        "ai-library": {
          "command": "npx",
          "args": [
            "-y",
            "mcp-remote",
            "https://mcp-1st-birthday-ai-digital-library-assistant.hf.space/gradio_api/mcp/sse"
          ]
        }
      }
    }
    ```

### 2. 🎧 Podcast Studio (Star Feature)
Turn your reading list into a playlist! The **Podcast Studio** is a flagship feature that transforms any selection of documents into an engaging, multi-speaker audio podcast.
-   **Intelligent Scripting**: Uses **LlamaIndex** and **OpenAI/Nebius AI** to analyze your documents and generate a natural, conversational script.
-   **Multi-Speaker Synthesis**: Leverages **ElevenLabs** to bring the script to life with distinct, realistic voices for each host.
-   **Customizable**: Choose your style (Educational, Casual, Teaching) and duration.
