How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Worldwide eSIM to help me. It is a free service with an MCP server at https://worldwideesim.com/wp-json/worldwideesim/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- 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 180 days from the first connection), recharge, delivery, installation, devices, payment, refu
- 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

- 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
