Systemic Vascular Resistance (SVR) and Total Peripheral Resistance Index (TPRI) Quantitative Analyzer. Evaluates left-ventricular afterload and peripheral vascular compliance.

    A[SBP, DBP, and Central Venous Pressure] --> B[Calculate MAP = DBP + SBP - DBP / 3]
    C[Height & Weight] --> D[Mosteller BSA Formula]
    B & E[Cardiac Output CO] --> F[SVR = 80 * MAP - CVP / CO]
    F & D --> G[TPRI = SVR * BSA]
    G --> H[Autonomic Vascular Afterload Evaluation]
```

## Features
- **Zero PIP Dependencies**: Implemented strictly with Python Standard Library (`math`, `json`, `sys`, `typing`).
- **Standard Cardiovascular Hemodynamics**: Evaluates SVR in dyn*s/cm^5 and indexed TPRI in dyn*s*cm^-5*m^2.
- **Precision Anthropometry**: Incorporates Mosteller body surface area adjustment.
- **Dual Architecture**: Native Python import and Model Context Protocol (MCP) JSON-RPC 2.0 stdio server.

## Quickstart
```bash
python example_usage.py
```
