Features

  • Zero PIP Dependencies: Implemented strictly with Python Standard Library (math, json, sys, typing).

  • Pressure-Volume Framework: Single-beat validated elastance and coupling models.

  • Cardiovascular Energetics: Direct computation of stroke work mechanical efficiency.

  • Dual Architecture: Native Python import and Model Context Protocol (MCP) JSON-RPC 2.0 stdio server.
