GeoSpark
Verifiable geospatial tools: distances, topology, isochrones, Overture Maps, with sources.The vendor's description, from its MCP Registry listing.
Every public check ran and passed. Public audit: we connect as an AI client would, list the tools and check what they say. We do not run them. How we audit
- Does it work?
- YesConnected in 885 ms.
- Sign-up?
- None neededIt answered without any account or key.
- Can it change things?
- No, read-onlyAll 21 tools say they only read.

Tools (21)
As the server describes them. The labels are the server's own: it says whether each tool only reads or can change things.
- calculate_distanceExact geodesic distance between two places or geometries on the WGS84 ellipsoid. Use for any "how far" question instead of estimating. For NAMED places pass place_a and place_b; the…Read-only

- get_air_qualityLatest PM2.5, NO2, O3 from the nearest monitoring stations (OpenAQ; the server needs an OPENAQ_API_KEY), with each station's data licence.Read-only
- get_active_firesSatellite active-fire detections near a point (NASA FIRMS; the server needs a FIRMS_MAP_KEY).Read-only
- isochroneWhere can you get to from a point within N minutes on foot, by bike or by car? Returns one polygon per contour with its geodesic area (Valhalla over OpenStreetMap).Read-only
- travel_time_matrixNetwork travel time (minutes) and distance (metres) from each origin to each destination. Note: points here are [latitude, longitude] pairs.Read-only
- overture_featuresOpen global map data from Overture Maps, no API key: points of interest (with categories), building footprints (height, floors, geodesic footprint area), road and path segments (geode…Read-only
- transform_coordinatesConvert coordinates between CRSs as the official transformation does: GDA94 to GDA2020, MGA zones, British National Grid (OSTN15), NAD27 to NAD83 (NADCON), ITRF at an epoch, and any o…Read-only
- convert_heightConvert a height between the ellipsoid (GNSS, drones) and a national height datum with the official geoid model: AHD (AUSGeoid2020), ODN (OSGM15), NZVD2016 (NZGeoid2016), NAVD88 (GEOI…Read-only
- sun_positionThe Sun's apparent elevation and azimuth (from true north) at a place and time, and the shadow a vertical object casts on level ground (NOAA solar position, refraction included).Read-only
- sun_timesSunrise, solar noon, sunset and day length on a date for a flat horizon; with terrain=True, also the hours of direct sun once hills are taken into account.Read-only
- terrain_horizonThe skyline the terrain makes around a point: for each azimuth, the elevation angle of the horizon and how far away the blocking terrain is (Copernicus 30 m DEM, Earth curvature and r…Read-only
- line_of_sightWhether A and B can see each other over the terrain (Copernicus 30 m DEM, curvature and refraction), the minimum clearance and where it occurs; with frequency_mhz, the first Fresnel z…Read-only
- location_reportA dossier for a place: address, elevation, weather, and nearby amenities with exact distances, as a GeoJSON map layer listing every data source used. Takes ~10-30 s.Read-only
- select_siteRank candidate sites in an area by geodesic distance to amenities you want nearby and away from ones to avoid (OpenStreetMap data). Takes ~10-30 s.Read-only
