cities_by_coordinates_closest
Find cities nearest to given coordinates, ordered by distance.
LABSCO SUMMARY
You can try it before subscribing to anything.
Keyless mode is not a crippled trial: the autocomplete tool runs against pre-built static files, which is why it stays the fastest search path even after you add a key. The compound tools are where the subscription pays for itself — city_context and country_overview each replace three calls.
What it is
An MCP server over the Geomelon geographic API. It covers cities with population and name translations, countries and their administrative regions, distances and nearest-city lookups, plus compound tools that chain several API calls into one round trip.
What you get
- Cities — search_cities, get_city, get_city_translations, get_city_settlement_types, cities_by_coordinates_closest, cities_by_coordinates_largest, cities_distance
- Countries and regions — list_countries, get_country, get_country_translations, get_country_regions, list_regions, get_region, get_region_translations
- Languages — list_languages, get_language
- Compound calls that save round trips — find_cities_near_city, city_context, country_overview, compare_cities, search_cities_in_country
- search_cities_autocomplete is a country-scoped, language-specific prefix search backed by pre-built static files: the only tool available without a key, and the fastest search path once you have one
Requirements
Node.js 18 or newer. The geomelon-mcp package ships two binaries: geomelon-mcp over stdio for Claude Desktop, Cursor, Cline and Continue, and geomelon-mcp-http for Streamable HTTP. GEOMELON_API_KEY is a RapidAPI key with the Geomelon API subscribed; without it the server still starts, exposing search_cities_autocomplete only. A public keyless instance runs at https://mcp.geomelon.dev/mcp. The HTTP transport is stateless with CORS open, PORT changes the port it binds, and GET / returns a status object saying whether that instance has a key.

USE CASES
01
Turning a typed prefix into real cities
Country-scoped, language-specific prefix search, sorted by population, with an English fallback name.
02
Getting a city with its country and region attached
One call instead of three, or two cities and the distance between them in one.
03
Finding what is near a coordinate pair
Nearest cities by distance, or the largest ones in the area by population.
04
Profiling a country quickly
The country, all its administrative regions and its most populous cities, from a UUID or a name prefix.
05
Showing a place name in the reader's language
Every available translation for a city or region, rather than guessing the local spelling.
22 tools
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
cities_by_coordinates_largest
Find the largest cities near given coordinates, ordered by population.
cities_distance
Calculate the distance in kilometres between two cities.
city_context
Get a city together with its full country and region details in one call.
compare_cities
Fetch full details for two cities and the distance between them in one call.
country_overview
Get a country's details, all its regions, and its most populous cities in one call. Accepts either a country UUID or a name prefix.
find_cities_near_city
Find cities near a given city. Resolves the city's coordinates and returns nearby cities ordered by distance or population.
get_city
Get full details for a single city by its UUID.
get_city_settlement_types
Get settlement-type classifications for a city (e.g. city, town, village) by its UUID.
get_city_translations
Get all available name translations for a city by its UUID.
get_country
Get full details for a single country by its UUID, including translations and regions.
get_country_regions
Get all administrative regions belonging to a country by its UUID.
get_country_translations
Get name translations for a country by its UUID.
get_language
Get details for a single language by its UUID.
get_region
Get full details for a single region by its UUID.
get_region_translations
Get name translations for a region by its UUID.
list_countries
List countries with optional filtering by name prefix or telephone code. Supports localized names via preferredLanguages.
list_languages
List languages available in the Geomelon database.
list_regions
List administrative regions, optionally filtered by country.
search_cities
Search cities by name, country, population range, and more. Returns matching cities with geographic and translation data.
search_cities_autocomplete
Fast country-scoped, language-specific city name prefix search backed by pre-built static files. Works without a Geomelon API key. Returns up to 10 cities sorted by population, with the requested language name and an English fallback.
search_cities_in_country
Search cities using a country name instead of an ISO code. Resolves the country first, then searches cities within it.
BEFORE YOU INSTALL
What to know first
Tools you get
22 tools when we connected. Without GEOMELON_API_KEY only search_cities_autocomplete registers, and the public hosted instance at mcp.geomelon.dev runs in that keyless mode; run your own instance with a RapidAPI key for all 22.
Requires
- npx on PATH
- Node.js 18+
Optional
GEOMELON_API_KEY in your environment
