Tutorials

Task-driven walk-throughs. Each tutorial assumes you have an MCP client connected to https://mcp.io-aerospace.org/mcp and have signed in. See Quick Start if not.

Tutorial	Level	What you learn
Connecting an MCP client	Beginner	Wire up Claude Desktop, the TypeScript SDK, or MCP Inspector
Ephemeris queries	Beginner	Get state vectors of planets, moons and barycenters
Coordinate conversions	Beginner	Frame rotations and equatorial coordinates
Orbits and elements	Beginner	Keplerian, equinoctial, Cartesian, and anomalies
TLE propagation	Beginner	Parse and SGP4-propagate a Two-Line Element set
Maneuvers and transfers	Intermediate	Hohmann, bi-elliptic, plane changes, phasing
Geometry and visibility	Intermediate	Visibility windows, eclipses, illumination
Mission scenarios	Advanced	End-to-end propagation with maneuvers, perturbations, constraints

The JSON payloads in these tutorials show the arguments of a tools/call. Most MCP clients will hand them to the LLM through their prompts; you generally do not write them by hand.
