navigation toolkit

This MCP server gives LLM/AI/Agents the ability to provide accurate navigation information. There are three main application areas (all can be combined): time & place, road-trips, and general aviation.

Time and Place

Accurate determination of local time and sun position at any place in the world, taking into account time zones and daylight savings corrections.

LLM prompt examples using these tools:

“How many hours of daylight will there be on the Isle of Man on June 15th this year?”

“What time is it in Hong Kong right now, and what are the light conditions (daylight, twilight, or darkness)?”

“What time is sunrise and sunset in Hamburg, Germany tomorrow?”

“My flight is departing for San Francisco from London at 3 hours from now. The flight will take ten hours. What time will it be when I arrive in San Francisco, and what will the lighting conditions be?”

Roadtrips

Accurate determination of driving distances and times anywhere in the world, taking into account current traffic (and allowing for ferry trip times if water crossing required). Computation of latitude and longitude for any place specified by address, postal code, name, landmark, etc. Search for hotels, restaurants, or any other typical feature, within a specified range of any location.

LLM prompt examples using these tools:

“What is the distance, and how long will it take, to drive from Joshua Tree to Oakland CA?”

“Find me 10 hotels within 20 miles of Prestwick Airport, UK”

“What is the latitude and longitude of UK postcode IM4 7BN?”

“If I drive from Berlin to Munich tomorrow, departing at 9am local time, will it be dark when I arrive?”

General Aviation

Provides tools for the following

• Accurate computation of distances between points on Earth using the World Geodetic System 1984 (WGS84), the geodetic reference system that defines the Earth’s shape and size as an oblate spheroid, the standard for the Global Positioning System (GPS). The distances can be computed either as great-circles (i.e., shortest distance between the two points) or rhumblines (i.e., the distance measured along a straight line drawn on a mercator projection map).
• Accurate computation of the end-point for a given start-point, bearing, and range. The bearing can be referenced to either true or magnetic north (if magnetic, the magnetic variation is automatically calculated and corrected for), and the track can be specified as a great circle or rhumbline.
• Search for airports within a specified range from any location in the world, with multiple optional filters (such as “must have AVGAS” etc). For the US only, can also search for navaids, fixes, features, and obstacles.
• Obtain the latest aviation weather report (METAR) and forecast (TAF) for any worldwide ICAO designated weather station (in raw and decoded formats).
• Find the nearest ICAO designated weather station to a given location, or multiple stations within a specified range of that location.
• Computation of aviation-pertinent atmospheric parameters (versus altitude) given the measured temperature and pressure (from METARs).
• Perform VFR (Visual-Flight-Rules) flight route calculations between specified origin and destination airfields, plus up to ten optional intermediate waypoints (when not routing direct).
• Automatically computes wind corrections (using latest METARs along the route, and assuming a power-law extrapolation from METAR measured winds at 10m AGL to wind aloft), magnetic variation, and sunlight conditions (e.g., if daylight, twilight, or night-time at each waypoint plus direction (azimuth and zenith) to the sun relative to flight track (to assess if glare will be an issue).
• For the origin and departure airfields, gives essential information for each runway (surface, dimensions) plus the crosswind and headwind/tailwind components (computed from latest METARs), pl
