Geomelon tools (22)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • cities_by_coordinates_closest

    Find cities nearest to given coordinates, ordered by distance.

  • 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.

What its tools let an agent do: 22 read

Install Geomelon in Claude Code, Cursor or VS Code

Runs npx -y geomelon-mcp on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add geomelon-mcp -- npx -y geomelon-mcp
Add to Cursor

What the publisher says

From the Geomelon repository's README, as published. We do not edit it. Read it on GitHub

geomelon-mcp

MCP server for the Geomelon geographic API. Exposes cities, countries, regions, and languages as tools any MCP-compatible AI client can call.

Looking for other ways to integrate? See all official libraries at geomelon.dev/libraries.

Two transports are included:

Requirements

  • Node.js 18+
  • A RapidAPI key with the Geomelon API subscribed — optional, see keyless demo mode below

Keyless demo mode

No GEOMELONAPIKEY? Run the server anyway — it starts up with just the searchcitiesautocomplete tool, backed by the free oneshot host, no signup required. Every other tool needs a key. This is the fastest way to try the server before subscribing on RapidAPI.

Try it with zero setup

Geomelon also runs a public hosted instance of this same keyless demo — no npx, no local process. Point any remote-MCP-capable client (Claude web/desktop connectors, ChatGPT connectors, MCP Inspector, etc.) at:

https://mcp.geomelon.dev/mcp

It exposes only searchcitiesautocomplete, same as running the server yourself with no API key. For the full 22-tool set, run your own instance (below) with your RapidAPI key.

Claude Code (HTTP)

Create a .env file in the directory you'll run the server from:

cp .env.example .env
# then edit .env and set GEOMELON_API_KEY

Start the server (dotenv loads .env automatically):

npx geomelon-mcp-http

Register it with Claude Code:

claude mcp add --transport http geomelon http://localhost:3000/mcp

Verify it's connected:

claude mcp list

The server must be running whenever you use Claude Code. To use a different port set PORT=your_port and update the URL in the claude mcp add command accordingly.

Claude Desktop (stdio)

Add to ~/Library/Application Support/Claude/claudedesktopconfig.json:

{
  "mcpServers": {
    "geomelon": {
      "command": "npx",
      "args": ["-y", "geomelon-mcp"],
      "env": {
        "GEOMELON_API_KEY": "your_rapidapi_key_here"
      }
    }
  }
}

Restart Claude Desktop after saving.

Cursor / Windsurf / Cline (stdio)

Add to your editor's MCP config:

{
  "geomelon": {
    "command": "npx",
    "args": ["-y", "geomelon-mcp"],
    "env": {
      "GEOMELON_API_KEY": "your_rapidapi_key_here"
    }
  }
}

Remote / hosted HTTP server

Create a .env file on your server:

cp .env.example .env
# set GEOMELON_API_KEY and PORT in .env

Start the server:

npx geomelon-mcp-http

Then register with any MCP client using http://your-host:3000/mcp as the URL.

The HTTP transport is stateless — each request is independent, no session management needed. CORS is wide open (Access-Control-Allow-Origin: *) since this transport is meant to be reachable by browser-based remote-MCP clients too. GET / (or /health) returns a small JSON status object — useful for uptime checks — reporting whether the instance has a key configured ("mode": "full" or "mode": "keyless-demo").

Yes. The registry entry asks for GEOMELON_API_KEY, PORT.
Is Geomelon maintained?
The last commit was 110 days ago (2026-07-17). The latest release is v1.1.1.
How does Geomelon compare with other MCP servers?
safety score 77/100 (higher than 50% of 48,255 servers); tools 22 (the typical server has 7); tools that change things 0% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
