930m310n tools (21)

write = sends, deletes, buys or posts

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

How 930m310n compares

Against every graded MCP server, from our own scans and uptime checks. Updated after each scan run.

Safety score: 77/100; higher than 50% of 48,255 servers
Tools: 21; the typical server has 7
Tools that change things: 0%; typical: 0%. Fewer write tools means less an agent can break
GitHub stars: 1; more than 65% of 28,688 servers
Downloads a week: 81; more than 58% of 12,191 servers with a package

What its tools let an agent do: 21 read

Install 930m310n 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 mcp -- npx -y geomelon-mcp

Add to Cursor

What the publisher says

From the 930m310n 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

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").
