Methodology

  • Both servers use identical tool implementations (imported from shared_tools.py)
  • Each scenario runs in an isolated server subprocess
  • Warmup period excluded from measurements
  • Load generated by async httpx workers (not external tools)
  • MCP tests use full protocol lifecycle (initialize → call_tool)
  • System metrics sampled every 1s via psutil
