What it can do

Tool names and descriptions exactly as the server reported them on Nov 13, 2026. The maker wrote them, not us; we show them as plain text.

  • search_destinations

    Find a travel destination (country) sold by eSIM SOS by name in English or Russian, or by ISO code. Returns country codes for list_plans.

  • compare_prices

    Compare eSIM prices of several providers for a country and data size using the open esimdar.com dataset (CC BY 4.0). Disclosure: esimdar.com is owned and run by eSIM SOS, the shop behind this server; eSIM SOS is listed as an ordinary row. Tell the user about this ownership and pr

  • create_order

    Create an unpaid eSIM order and get a payment link. Payment is always done by the human: give the user the payment link, never try to pay yourself and never ask for card details. Ask the user for their email first: the eSIM QR code is sent there. Creates a real order, so call it

  • order_status

    Check the payment and delivery status of an order. Requires both order_id and the email used for the order.

  • install_instructions

    After payment: link to the order page with the QR code and step-by-step eSIM install instructions for iPhone and Android. Requires order_id and email.

Common questions

Is eSIM SOS safe?

It passed 4 of 4 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 in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 36 days ago, and the latest version (1.0.0) reached the registry 36 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

eSIM SOS MCP server

English · Русский

English

An MCP server for eSIM SOS, a travel eSIM shop. It lets Claude, ChatGPT, Cursor and other AI agents find a data plan for a trip, compare prices with other providers and create an order. The human always pays: the server returns a payment link, it never accepts card details and the AI never pays by itself.

Two ways to connect:

  • Remote (recommended): https://esimsos.net/api/mcp (Streamable HTTP, no sign-in).
  • Local: the esimsos-mcp package (stdio), installed straight from GitHub with npx -y github:uziame/esimsos-mcp (npm release coming soon). It is a thin proxy to the remote endpoint and needs no keys.
Tools
ToolWhat it does
search_destinations(query)Find a country by English or Russian name or ISO code
list_plans(country, min_gb?, days?)Plans with final prices in RUB (one price for every payment method)
compare_prices(country, gb)Prices of several providers from the open esimdar.com dataset (CC BY 4.0). esimdar.com is run by eSIM SOS; eSIM SOS is listed as an ordinary row
create_order(plan_id, email, payment_method?)Creates an unpaid order, returns order_id and payment_url for the user
order_status(order_id, email)Payment and delivery status (only when the email matches the order)
install_instructions(order_id, email)After payment: order page with the QR code and steps for iPhone and Android

Payment methods: sbp (Russian fast payments), card (Russian bank card), card_foreign (Visa/Mastercard issued abroad), crypto_usdt, crypto_ton.

Example prompts
  • "I'm flying to Turkey for two weeks. Find an eSIM with at least 10 GB."
  • "Compare 5 GB eSIM prices for Georgia."
  • "Order the 10 GB / 30 days plan for Turkey, my email is anna@example.com."
  • "Has my order cmg... been paid? Email anna@example.com."
  • "How do I install the eSIM on my iPhone?"
Connect

Claude.ai, Claude Desktop, Cowork (remote). Settings → Connectors → Add → Add custom connector → URL https://esimsos.net/api/mcp → Add. No authentication is needed. Docs: Get started with custom connectors, Connect to remote MCP servers.

Claude Desktop (local, npm). Settings → Developer → Edit Config, then add to claude_desktop_config.json (macOS ~/Library/Application Support/Claude/, Windows %APPDATA%\Claude\) and restart Claude. Requires Node.js 18+. Docs: Connect to local MCP servers.

{

"mcpServers": { "esimsos": { "command": "npx", "args": ["-y", "github:uziame/esimsos-mcp"] } } }

Cursor. Add to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project). Docs: Cursor MCP.

{

"mcpServers": { "esimsos": { "url": "https://esimsos.net/api/mcp" } } }

Or the local package: { "mcpServers": { "esimsos": { "command": "npx", "args": ["-y", "github:uziame/esimsos-mcp"] } } }.

ChatGPT. Plugins → + → Add custom MCP server → enter a name and the URL https://esimsos.net/api/mcp, authentication: none → confirm the warning → Create as a plugin. Then start a new chat and pick the plugin with @. Availability depends on your plan and workspace policy. Docs: Connect and test your plugin.

Any other client: use the remote URL with Streamable HTTP, or run npx -y github:uziame/esimsos-mcp over stdio. To debug: npx @modelcontextprotocol/inspector.

Privacy and limits
  • The email is used only for the order and the eSIM QR code. No reminders or marketing emails are sent to it.
  • order_status and install_instructions answer only when both order_id and email match.
  • Rate limits apply per email, per order and per IP.
  • Orders created through MCP are counted with utm_source=mcp.
  • ESIMSOS_MCP_URL overrides the endpoint for the npm package (for testing).

Русский

MCP-сервер магазина eSIM SOS (eSIM для путешествий). С ним Claude, ChatGPT, Cursor и другие ИИ-агенты подбирают тариф под поездку, сравнивают цены с другими магазинами и оформляют заказ. Платит всегда человек: сервер возвращает ссылку на оплату, данных карты не принимает, сама нейросеть не платит.

Два способа подключения:

  • Удалённо (рекомендуем): https://esimsos.net/api/mcp (Streamable HTTP, без входа).
  • Локально: пакет esimsos-mcp (stdio), ставится прямо с GitHub: npx -y github:uziame/esimsos-mcp (в npm выйдет позже). Тонкий посредник к удалённому адресу, ключи не нужны.
Инструменты
ИнструментЧто делает
search_destinations(query)Находит страну по названию на русском или английском или по коду ISO
list_plans(country, min_gb?, days?)Тарифы с итоговой ценой в рублях (одна цена для всех способов оплаты)
compare_prices(country, gb)Цены нескольких магазинов из открытого набора esimdar.com (CC BY 4.0). esimdar.com делает eSIM SOS, eSIM SOS в нём — обычная строка
create_order(plan_id, email, payment_method?)Создаёт неоплаченный заказ, возвращает order_id и payment_url для человека
order_status(order_id, email)Статус оплаты и выдачи (только если почта совпадает с заказом)
install_instructions(order_id, email)После оплаты: страница заказа с QR и шаги для iPhone и Android

Способы оплаты: sbp (СБП), card (карта российского банка), card_foreign (зарубежная Visa/Mastercard), crypto_usdt, crypto_ton.

Примеры запросов
  • «Лечу в Турцию на две недели, подбери eSIM от 10 ГБ».
  • «Сравни цены на eSIM 5 ГБ для Грузии».
  • «Оформи тариф 10 ГБ на 30 дней для Турции, почта anna@example.com».
  • «Оплачен ли мой заказ cmg...? Почта anna@example.com».
  • «Как поставить eSIM на iPhone?»

ChatGPT. Plugins → + → Add custom MCP server → название и адрес https://esimsos.net/api/mcp, аутентификация не нужна → подтвердите предупреждение → Create as a plugin. Затем новый чат и выбор плагина через @. Доступность зависит от тарифа и правил рабочего пространства. Документация: Connect and test your plugin.

Другие клиенты: удалённый адрес по Streamable HTTP или npx -y github:uziame/esimsos-mcp по stdio. Для отладки: npx @modelcontextprotocol/inspector.

Данные и ограничения
  • Почта нужна только для заказа и QR-кода eSIM. Напоминаний и рассылок на неё не приходит.
  • order_status и install_instructions отвечают, только если совпали и order_id, и почта.
  • Есть лимиты запросов по почте, по номеру заказа и по IP.
  • Заказы через MCP учитываются с меткой utm_source=mcp.
  • ESIMSOS_MCP_URL меняет адрес для npm-пакета (для проверки).
