Overview

Description from the maker (original English)

Every country in Arabic and English: names, nationalities, dial codes, phone validation.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Other

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "worldref": {
      "command": "npx",
      "args": [
        "-y",
        "worldref",
        "mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add worldref -- npx -y worldref mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "worldref": {
      "command": "npx",
      "args": [
        "-y",
        "worldref",
        "mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "worldref": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "worldref",
        "mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Worldref safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.2) reached the registry 2 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

worldref

Every country in Arabic, English, or both: names, nationalities, capitals, currencies, languages, time zones, dial codes, phone validation, address formats and subdivisions. One dataset, ready for JSON, CSV, SQL, TypeScript, Python, Swift, Kotlin, Dart, PHP, Go and C#, and for AI agents (MCP).

العربية · Website and search demo · Best practices · Field reference · Data sources

import { countries, search, parsePhone, byIso2 } from "worldref";

byIso2("SA").name_ar; // "السعودية" byIso2("SA").nationality.nationality_ar_f; // "سعودية" search(countries, "الامارات", "ar")[0].iso2; // "AE" (ignores «ال», hamza and tashkeel) parsePhone("٠٥٠١٢٣٤٥٦٧", byIso2("SA")); // { e164: "+966501234567", valid: true, mobile: true, ... }

Why worldref

  • Arabic done natively. Short common names (السعودية, not a transliteration), nationality in masculine and feminine (سعودي / سعودية), search that ignores «ال», tashkeel, tatweel and hamza forms, Arabic-Indic and Persian digits accepted everywhere, and sort keys that give correct Arabic alphabetical order on every platform.
  • Works for one language or two. Every file comes in three builds: bilingual (name_ar, name_en), Arabic-only (name) and English-only (name).
  • Phone fields that work. Dial codes, valid lengths, mobile prefixes and exact validation patterns for every country, shared calling codes resolved (+1, +7, +44...), and international (E.164) output.
  • Everything a form or app needs in one place: official names, capitals, currencies with symbols (including the new Saudi riyal sign), official languages, week start and weekend, preferred calendars (including Umm al-Qura), postal code rules, address templates, emergency numbers, plug types and voltage, FIFA and IOC codes, and ISO 3166-2 subdivisions.
  • Sourced, not guessed. Official sources first (Unicode CLDR, Google libphonenumber, World Bank, IANA, ITU and government sources). Every column names its source in data/sources.json. A missing value is null, never a guess or a machine translation.

Each language folder has its own README with a usage example: python, Swift, kotlin, dart, php, go, csharp.

Use only what you need

  • The data is split into modules that share the key iso2: core, nationality, phone, currency, geo, locale, address, travel, sports, plus subdivisions. Find them in data/modules/.
  • Each module comes in 3 builds: .json (Arabic and English), .ar.json (Arabic only), .en.json (English only).
  • JS/TS: import only the module you use, and your bundler ships only that file:
  import phone from "worldref/data/modules/phone.json" with { type: "json" };

import { parsePhone } from "worldref/helpers";

- **Other languages:** load only the module files you need. [`data/worldref.json`](data/worldref.json) has everything.
  • One country, no install: https://arj-89.github.io/worldref/api/v1/{iso2}.json.
  • A missing value is null (or an empty list). Treat it as unknown; never fill it in.
  • Within a major version, fields are never renamed or removed.

Recipes

Country picker (user's country first, then alphabetical in the UI language):

import { countries, sortCountries, search } from "worldref";

const list = sortCountries(countries, "ar", "SA"); // السعودية first, then Arabic order const hits = search(countries, userQuery, "ar"); // names, aliases, ISO codes, +966 / 00966 / 966

Show: flag, name in the UI language, then the dial code. In Arabic, isolate the dial code left-to-right (`<bdi dir="ltr">+966</bdi>`).

Phone field (store the international form plus the country the user picked):

const p = parsePhone(input, byIso2(pickedIso2), countries);

if (p?.valid && p.mobile) save({ phone: p.e164, phone_country: p.iso2 });

Nationality field (only rows that have one: countries, plus Taiwan, Hong Kong and Macau):

const options = countries.filter((c) => c.nationality.nationality_en);

const label = (c, female) => (female ? c.nationality.nationality_ar_f : c.nationality.nationality_ar_m);

Database seed: run data/sql/postgres.sql (or mysql.sql, sqlite.sql). It creates countries and subdivisions.

Best practices

Every rule below is built into the helpers of all eight packages and locked by the shared tests in tests/vectors.json. Use the helpers; if you write your own, follow these rules exactly.

Search (normalize(), search())

  • Normalise both sides, the query and the names, the same way.
  • Arabic: drop «ال» at the start of every word (not only the first); remove tashkeel (fatha, damma, kasra, sukun, shadda, tanween) and tatweel (ـ); treat أ إ آ ٱ as ا, ة as ه, ى as ي, ؤ as و, ئ as ي. So «الإمارات», «امارات» and «الأمارات» all find the UAE.
  • Latin: ignore case and accents, and treat punctuation as a space, so «cote d'ivoire» finds Côte d’Ivoire.
  • Digits: convert Arabic-Indic (٠١٢٣٤٥٦٧٨٩) and Persian (۰۱۲۳۴۵۶۷۸۹) digits to Western before anything else.
  • Match names and aliases in both languages, ISO codes (SA, SAU), and dial codes with or without «+» or «00» (+966, 00966, 966).

Sorting (sortCountries())

  • Put the user's country first: from their profile, else the device region, else pin nothing.
  • Then sort by sort_ar or sort_en with plain string comparison. Do not use locale collation (Intl.Collator("ar"), localizedStandardCompare): neither ignores «ال», so every «ال» name bunches under ا.

Display

  • Show the flag, then the name in the UI language, then the dial code.
  • In Arabic, isolate the dial code and any Latin text left-to-right in the UI ( +966 , or U+2066 ... U+2069). The data never contains bidi marks.
  • Show Western numerals (0-9) in the UI, in both languages.
  • Use flag_svg on the web: Windows does not draw flag emoji.
  • Currency: show symbol (the Saudi riyal sign is U+20C1) and fall back to symbol_fallback (ر.س) where the font lacks the new sign.

Phone fields (parsePhone(), formatNational())

  • Accept whatever the user types: Arabic or Western digits, spaces, dashes, a leading 0, «+» or «00».
  • Store the international form (e164) together with the iso2 the user picked. Shared calling codes (+1, +7, +44, +599...) cannot be read back to one country from the number alone.
  • Validate a mobile with mobile_pattern. Where mobile_distinguishable is false (US, Canada), do not reject a number for not looking like a mobile.
  • Format for display with formatNational() (5X XXX XXXX style).

Nationality fields

  • List only rows where nationality.nationality_en is not null (countries, plus Taiwan, Hong Kong and Macau).
  • In Arabic, use the form that matches the person: nationality_ar_m (سعودي) or nationality_ar_f (سعودية).

Data

  • null (or an empty list) means unknown. Show it as unknown; never fill it from elsewhere.
  • Load only the modules you need; they join on iso2.
  • Pin a version (#v1.1.2, @1.1.2) so names and rules do not change under you.

Data policy

  • Israel is not in this dataset, in any file, under any name or code. A test enforces this on every output.
  • Palestine is «فلسطين» / "Palestine", a country, with its capital «القدس» / "Jerusalem". Numbers with +970 and +972 (including Jerusalem and the 1948 lines) are Palestinian numbers here. Its currencies are the Jordanian dinar and the shekel (shown as «شيكل» / "Shekel").
  • Disputed places follow the official positions of Saudi Arabia: Western Sahara is part of Morocco (no separate row), Kosovo is included, Northern Cyprus is not, and Taiwan, Hong Kong and Macau are territories that still have a nationality (they issue their own passports).
  • Requests to change this policy are closed without discussion. Corrections to data are welcome with a source link (see CONTRIBUTING).

Fields

Single-language builds drop the _ar / _en suffix (name_ar becomes name in .ar.json).
