A **Model Context Protocol (MCP)** server for political bias detection using a fine-tuned T5-large model with LoRA adapters. This server provides tools for analyzing news articles, opinion pieces, and political commentary for political leaning.

## Features

- **Political Bias Detection**: Analyzes text for Left/Center/Right political leaning
- **Bias Intensity**: Measures Low/Medium/High degree of bias
- **Reasoning**: Provides explanations for classifications
- **Hardware Acceleration**: Supports MPS (Apple Silicon), CUDA, and CPU
- **MCP Integration**: Works with AI assistants that support the Model Context Protocol
- **Batch Processing**: Analyze multiple texts efficiently

## Installation

### From PyPI (Recommended)

```bash
pip install bias-mcp-server
```

**That's it!** The package includes the trained LoRA adapter (~18MB), so it works out of the box.

### Quick Start

```python
from mcp_bias_server.bias_engine import BiasEngine

# Works immediately - no additional setup needed
engine = BiasEngine()
result = engine.analyze("Your news text here...")
print(result.to_dict())
```

### From Source

```bash
git clone https://github.com/yourusername/bias-mcp-server.git
cd bias-mcp-server
pip install -e .
```

## Usage
