What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • get_shop_facts

    What worldwide eSIM is and how it works, in the shop’s own words: one mobile-data eSIM for the whole world or chosen continents, one data pool, validity (until the data is used up, up to 90 days from the first connection), recharge, delivery, installation, devices, payment, refun

  • list_coverage

    The five continents with their number of countries and the starting price of each (the smallest data size for that continent alone) plus the whole world. Pass continent to list its countries (continent "world" lists every country); include_networks adds the operator names and a 5

  • check_country

    Is one country included? Pass its name in any language or its ISO-2 code (map a city to its country first). Returns included true/false, the continent, the mobile networks (operator names + 5G flag) and the cheapest coverage choice that includes it (its continent alone) with the

  • quote_esim

    Use while the customer is still deciding — "how much is …?": the exact server price of ONE worldwide eSIM for the chosen continents (default: the whole world) and data size — the amount the customer would pay — with the number of countries, the validity (until the data is used up

  • price_grid

    Every data size (or the sizes asked for) for one coverage choice in one call, each with the server price and its own buy_url; with compare_continents also the whole world against each single continent — to show what a smaller coverage saves. Same server prices as quote_esim.

  • recommend_config

    Use when the customer names the countries of a trip instead of continents and a size: returns the smallest set of continents that covers every named country (countries that are not included come back in not_covered), a suggested data size from the days and usage (light ≈ 0.5 GB/d

  • start_checkout

    Use only once the customer has decided to buy ("I'll take it", "how do I buy?"): the checkout handoff for one choice (same input as quote_esim). Returns the buy_url to give the customer, the final price and a ready-to-send checkout block (next_step, payment_methods, delivery) — t

Common questions

Is worldwide eSIM — one eSIM for the whole world safe?

It passed 2 of 3 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 –, and the latest version (3.0.0) reached the registry 12 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 in developer mode.

What can I use instead?
