# Docs Navigator MCP
A powerful documentation assistant that combines **Model Context Protocol (MCP)** with **Claude AI** to provide intelligent Q&A over your documentation files. Built with FastMCP and Gradio for an easy-to-use web interface.

## ✨ Features

- 🔍 **Smart Document Search**: Full-text search across your documentation files
- 🤖 **AI-Powered Responses**: Uses Claude AI to provide intelligent answers based on your docs
- 📁 **Multi-Format Support**: Works with `.md`, `.txt`, `.rst`, and `.pdf` files
- 🌐 **Web Interface**: Clean Gradio-based chat interface
- ⚡ **MCP Integration**: Leverages Model Context Protocol for seamless tool integration
- 🔧 **Easy Setup**: Simple configuration and deployment
- 📄 **PDF Support**: Extract and analyze text from PDF documents

## 🚀 Quick Start

### Prerequisites

- Python 3.10 or higher
- An Anthropic API key
- UV package manager (recommended) or pip

### 1. Clone and Setup

```bash
git clone <your-repo-url>
cd docs-navigator
```

### 2. Install Dependencies

Using UV (recommended):
```bash
uv sync
```

Or using pip:
```bash
pip install -r requirements.txt
```

### 3. Configure Environment

Create a `.env` file:
```bash
echo "ANTHROPIC_API_KEY=your_api_key_here" > .env
```

### 4. Add Your Documentation

Place your documentation files in the `docs/` directory:
```
docs/
├── overview.md
├── setup.md
├── troubleshooting.md
└── your-other-docs.txt
```

### 5. Launch the Application

```bash
# Using UV
uv run app_gradio.py

# Or directly with Python
python app_gradio.py
```

The app will be available at `http://127.0.0.1:7860`

## 📚 Usage Examples

Once the app is running, you can ask questions like:

- "How do I set up the authentication?"
- "What are the troubleshooting steps for connection issues?"
- "Where can I find information about API endpoints?"
- "Summarize the main features mentioned in the docs"

The AI will search through your documentation and provide contextual answers with references to the source files.

## 🛠️ Development

### Project Structure

```
docs-navigator/
├── app_gradio.py          # Gradio web interface
├── client_agent.py        # MCP client and Claude integration
├── server_docs.py         # MCP server with doc tools
├── docs/                  # Your documentation files
├── tests/                 # Test scripts
│   ├── test_mcp.py       # Test MCP server functionality
│   ├── test_anthropic.py # Test Claude API connection
│   └── test_complete.py  # End-to-end functionality test
├── .env                   # Environment variables
├── pyproject.toml         # Project configuration
└── requirements.txt       # Python dependencies
```

### Available MCP Tools

The server exposes these tools to the AI:

1. **`list_docs()`**: Get a list of all available documentation files
2. **`search_docs(query, max_results)`**: Search for specific content across all docs

### Testing

Run the test suite:

```bash
# Test MCP server functionality
python test_mcp.py

# Test Claude API connection
python test_anthropic.py

# Test complete end-to-end functionality
python test_complete.py
```

## 🔧 Configuration

### Environment Variables

| Variable | Description | Required |
|----------|-------------|----------|
| `ANTHROPIC_API_KEY` | Your Anthropic Claude API key | Yes |

### Supported File Formats

- **Markdown**: `.md`
- **Text**: `.txt`
- **reStructuredText**: `.rst`
- **PDF Documents**: `.pdf` (text extraction)

### Model Configuration

The app currently uses `claude-3-haiku-20240307`. To change the model, edit the model name in `client_agent.py`:

```python
model="claude-3-haiku-20240307"  # Change to your preferred model
```

## 🐛 Troubleshooting

### Common Issues

1. **"Model not found" error**: Your API key may not have access to the specified Claude model. The app will automatically test available models.

2. **MCP connection issues**: Ensure the `server_docs.py` script is executable and in the correct location.

3. **No documents found**: Make sure your documentation files are in the `docs/` folder with supported extensions.

4. **Gradio interface not loading**: Check that port 7860 is available or modify the port in `app_gradio.py`.

### Debug Mode

Enable verbose logging by modifying the logging level in the respective files.
