What it can do

  • Starts and stops its own STK Engine or STK Desktop instance with the server.
  • Creates a scenario with a time period, ground facilities or places, and satellites from apogee, perigee, RAAN and inclination.
  • Resources list scenario objects, report health, compute access intervals between two objects and return satellite LLA ephemeris.
  • Serialises STK access with a lock and retries flaky Connect commands.

Limitations

  • Only three tools; create_satellite doesn't work with STK Engine on Linux.
  • macOS isn't supported, and the agi.stk12 wheel has to come from your STK install.
  • No licence file in the repository.

Install

uv add ./agi.stk12-12.10.0-py3-none-any.whl
uv sync
uv run -m stk_mcp.cli run --mode engine
