What it can do
Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.
plan-tripAnswer "which eSIM should I buy for this trip?". Give it the stops, a country code and the days spent in each, and it compares one plan covering the whole route against one plan per country against a mix of the two, on live prices, then flags the cheapest option that covers every
list-destinationsFind the countries SimFuse sells eSIMs for, with the cheapest plan price ("from" price) for each in the currency you ask for. Start here when someone names a place: it turns "Portugal" into the two-letter country code the other tools take, and shows what that destination starts a
list-regionsDiscover available eSIM regions, including worldwide scopes, with their canonical slugs, display names, member countries and starting prices. Only published regions with active displayed regional plans are listed. Pass a returned region slug to list-plans as region, not destinati
get-destination-infoDetails for one destination: its name and codes, region, how many eSIM plans are sold there, the cheapest and most expensive, the smallest and largest data bundles, and its storefront page. Takes a country name ("Japan") or two-letter code ("JP"). Use this to describe a destinati
list-plansShow the eSIM plans on sale for one country or region, or search the whole catalog, narrowing by data allowance, validity and price. Use destination with a country code from list-destinations, or region with a slug from list-regions; never both. Use it when the traveller wants to
get-planRead everything about one eSIM plan by its id: data allowance, how long it stays valid, what happens after a fair-use cap, whether hotspot and top-ups are supported, the network it runs on, and the retail price in the currency you ask for. Use it to answer a specific question abo
build-planBuild an eSIM plan to the traveller's liking for one destination: how much data, for how many days, optionally which network it runs on and whether calls and texts are bundled. Returns the one real plan that matches, with its id and live price, never a made-up combination: a shap
get-plan-coverageList every country one eSIM plan works in, plus any country of its own region that it leaves out. Use it to answer "does this plan also cover Austria?" for a regional or worldwide plan, where the plan name says a region and the traveller needs the actual list. For a single-countr
check-coverageAnswer "does this eSIM plan work in X?" for one destination, as a yes or no rather than a country list. Takes a plan id and a destination (a country name or two-letter code). Reports whether the destination is covered, and separately whether it is explicitly excluded from an othe
get-checkout-linkGet the page where a person buys one specific eSIM plan, for an assistant to hand them a link. The page sells exactly this plan with Apple Pay, Google Pay and card, takes the email at payment, and sends the eSIM there. Nothing is charged or reserved by this call and the buyer nee
create-checkout-sessionOpen a checkout session for one or more eSIM plans at frozen prices, using the plan ids that plan-trip, list-plans or get-plan returned. Use it once the traveller has chosen what to buy. It CHARGES NOTHING and reserves no stock: it prices the basket, freezes those prices until th
get-order-statusCheck an eSIM order after payment: whether it completed and whether its eSIMs have been provisioned yet. Identified by the order id together with the email that bought it, both of which are on the buyer's confirmation email. Provisioning usually finishes within a minute of paymen
get-esim-activationFetch the installable eSIM(s) for a paid order: the QR code image, the LPA activation string, the SM-DP+ address and activation code for manual entry, one-tap install links for iPhone and Android, and a hosted install page to send the buyer. Identified by the order id together wi
check-esim-usageHow much data an eSIM has used and how much is left, for one eSIM on a paid order. Identified by the order id and the email that bought it, plus the ICCID from get-order-status or get-esim-activation. Allowances are in megabytes. Readings are served from a cache refreshed every c
list-topup-optionsData top-ups that can be added to an eSIM the buyer already has, narrowed to what its network will actually accept. Identified by the order id and the email that bought it, plus the ICCID. Read-only: a top-up is bought in the SimFuse app, not through this server, and the response

Common questions
Is SimFuse eSIM Storefront 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 (1.2.0) reached the registry today.
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?
