MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Travel eSIMs for 130+ countries: plan a trip, compare plans, buy, install and diagnose.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
search_destinationsCountries and regions with eSIM plans, with the lowest price per currency. Leave query empty to list all.
list_plansPlans that work in a country or region, cheapest first, with optional filters for data, days and price.
get_planOne plan with prices and every country and mobile network it covers.
recommend_plansPlans for a trip to one or more countries: estimates the data needed from the days and how the user uses their phone, then suggests the best-value plans that cover every country for the whole trip.
compare_plansSide-by-side comparison of 2 to 5 plans: data, days, price per GB and per day, countries and hotspot.
country_networksThe mobile networks GLOBALCELL eSIMs use in a country, how many plans work there and the lowest price.
check_deviceWhether a phone, tablet or watch model supports eSIM, from a list of known models, with how to check on the device itself.
create_orderCreates an order and returns checkoutUrl, the page where the user pays; nothing is charged by this call. Without confirm: true it only returns a preview with the price and creates nothing. Returns orderId and orderToken for check_order.
check_orderOrder status. Once "fulfilled", a new eSIM includes its install links, QR code link and manual codes.
check_usageData used and left on the eSIM of a fulfilled order, per package, with start and expiry dates.
diagnose_esimWhy an eSIM may not work: line state, every package (started, data left, expired) and the last mobile network the phone registered on, with the likely cause and the fix. For the eSIM of a fulfilled order.
install_helpStep-by-step eSIM installation and first-use help for iPhone or Android, and fixes for common problems.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
The registry does not list a required key, though some servers ask you to sign in on first use.
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.
The GitHub repo last changed –, and the latest version (2.1.0) reached the registry 3 days ago.
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.
