Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Builds a file path from a variable geospark/geodesy.py:334

    installed = all(any(d and os.path.exists(os.path.join(d, n)) for d in dirs) for n in names)

Executes code built at runtime geospark/cli.py:243

            mod = __import__(module_name)

Page executes code built at runtime geospark/ui/agents.html:200, geospark/ui/api.html:122, geospark/ui/context.html:233 и ещё 5

        el.innerHTML = html;

Reads files and sends them to the network geospark/api.py:269

    for f in sorted(assets.rglob("*")) if assets.exists() else []:

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 21

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

spatial

check_spatial_relationship

Ground-truth topology: does geometry_a <relationship> geometry_b? Use instead of guessing containment, overlap or adjacency. Invalid geometries (for example self-intersecting polygons) are refused with the reason.

spatial_operation

Compute a buffer (shape-preserving, metres), geodesic area or length, centroid or convex hull. Returns the resulting geometry as GeoJSON with its measurements and units.

sun

sun_position

The 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).

sun_times

Sunrise, 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.

active

get_active_fires

Satellite active-fire detections near a point (NASA FIRMS; the server needs a FIRMS_MAP_KEY).

air

get_air_quality

Latest PM2.5, NO2, O3 from the nearest monitoring stations (OpenAQ; the server needs an OPENAQ_API_KEY), with each station's data licence.

calculate

calculate_distance

Exact 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 server geocodes them, so never type coordinates for a place yourself. Use point_a/point_b only for coordinates the user gave or another tool returned. For lines and polygons the distance is between their nearest points. Returns metres and kilometres.

convert

convert_height

Convert a height between the ellipsoid (GNSS, drones) and a national height datum with the official geoid model: AHD (AUSGeoid2020), ODN (OSGM15), NZVD2016 (NZGeoid2016), NAVD88 (GEOID18), or global EGM2008. Never estimate a geoid separation from memory: it is often tens of metres and varies by metres across a region.

elevation

get_elevation

Ground elevation in metres (Copernicus GLO-30, Open Elevation fallback), with its vertical datum and accuracy.

geocode

geocode

Find coordinates for an address or place name (OpenStreetMap Nominatim). Check `geospark.warnings` for ambiguous names (e.g. "Springfield") and ask the user which one they mean, or add a region.

isochrone

isochrone

Where 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).

line

line_of_sight

Whether 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 zone clearance of a radio link (60% clear is the usual rule).

location

location_report

A 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.

overture

overture_features

Open 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 (geodesic length), or `divisions`, the administrative areas containing the point (country, region, city, neighbourhood). Results are nearest first, with distances in metres. Can take 5-20 s on a cold cache.

reverse

reverse_geocode

Find the address or place at a coordinate (OpenStreetMap Nominatim).

route

route

Driving route between two points (OSRM over OpenStreetMap): line geometry, distance in metres and duration in seconds.

select

select_site

Rank 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.

terrain

terrain_horizon

The 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 refraction). Use for solar-panel shading, valley sunlight, or what hills hide. ~10-60 s.

transform

transform_coordinates

Convert 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 other EPSG pair. Uses national grids (downloaded once), refuses PROJ's ballpark approximations, and returns the operation and its stated accuracy. Use this instead of applying datum parameters yourself.

travel

travel_time_matrix

Network travel time (minutes) and distance (metres) from each origin to each destination. Note: points here are [latitude, longitude] pairs.

weather

get_weather

Current weather and a daily forecast for a point (Open-Meteo, no key needed).

GeoSpark — questions

Answers built from our own checks of this server.

What can GeoSpark do?

It exposes 21 tools, read directly from the server on our last check. Among them: calculate_distance, check_spatial_relationship, convert_height, geocode, get_active_fires, get_air_quality and 15 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is GeoSpark mostly used for?

Its tools cluster around sun and spatial. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is GeoSpark working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 1127 ms. The bar chart above shows every period we have measured.

How do I connect GeoSpark?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does GeoSpark need an API key?

No. GeoSpark completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 21 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is GeoSpark?

It answers our handshake in 1127 ms on average, which is faster than 4% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is GeoSpark open source?

The code is open source: it is published under the Apache-2.0 licence, written in Python, 20 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at geospark.terrascout.app, which runs on its operator's own terms.
