Tool Reference

Every MCP tool, grouped by class. Each page lists the tools in that class, their parameters, and a usage example.

The on-wire tool name is the C# method name (e.g. GetEphemerisAsStateVectors). Parameter names below match the JSON keys MCP clients see.

Bodies, frames, time

  • Celestial bodies — ephemeris and geophysical properties
  • Time — UTC/TDB/TAI/TDT/GPS conversions, Julian Date, ephemeris time
  • Frames — rotation and state-rotation matrices between frames
  • TLE — parse and SGP4-propagate Two-Line Element sets

Orbital mechanics

  • Orbital parameters — Keplerian / equinoctial / state-vector conversions, anomaly conversions, period, mean motion, apsides, energy, angular momentum
  • Maneuvers — closed-form delta-V for plane / apsides changes, phasing, Hohmann and bi-elliptic transfers
  • Lambert solver — multi-revolution two-impulse transfer

Sites and ground stations

Geometry

  • Observation geometry — angular separation, angular size, light time, range rate, sub-observer point, phase angle, illumination fraction
  • Geometry finder — time windows where a coordinate / distance / angular-separation / phase-angle / elevation / occultation constraint is satisfied

Scenario simulation

  • Scenario simulation — end-to-end mission propagation with maneuvers, perturbing bodies, drag, SRP, geopotential, and constraint evaluation
