## Tools (as reported by the server, not verified)

- `convert\_speed`: Convert a speed value between knots, mph, km/h, m/s, and ft/s.
- `convert\_coordinates`: Parse latitude and longitude and format them as decimal degrees or DMS.
- `calculate\_distance`: Calculate great-circle and rhumb-line routes between two GPS coordinates.
- `calculate\_bearing`: Calculate the initial true bearing between two GPS coordinates.
- `calculate\_cross\_track\_error`: Calculate cross track error \(XTE\) — the perpendicular distance from a vessel position to the great-circle track between two waypoints — plus side of track \(port/starboard\) and along-track distances.
- `list\_tools`: List the public Mariner GPS Tools calculators currently available.
