## Features
- **Deterministic Math**: Pure Python standard library implementation with zero external dependencies.
- **Clinical Neurological Standards**: Implements validated age-dependent Rydel-Seiffer cutoff formulas.
- **Hand-Arm Vibration & Large-Fiber Screening**: Non-invasive assessment of Pacinian mechanoreceptive integrity.
- **Model Context Protocol (MCP)**: Native JSON-RPC tool integration for LLMs and autonomous agents.

## Quickstart

```python
from client import VibrationPallesthesiaClient

client = VibrationPallesthesiaClient()
result = client.evaluate_vibration_threshold(
    rydel_seiffer_reading=7.5,
    age_years=32.0
)
print("Pallesthesia Score:", result["pallesthesia_sensory_score"])
print("Classification:", result["classification"])
```
