Common questions

Is esimoa — travel eSIM comparison 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 last month, and the latest version (1.1.0) reached the registry last month.

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).

What can I use instead?

Tools

Tool	What it does
`search_esims`	Search and compare plans. Filters: `country` (ISO code or name in any language) or `countries` (plans that work in all of them), `days`, `data_gb` / `max_data_gb`, `unlimited`, `data_type` (`daily` \	`total`), `local_number`, `network` (`local` \	`roaming`), `multi_country`, `min_price_krw` / `max_price_krw`, `provider`, `hotspot`, `five_g`. Sort: `recommended`, `price`, `data`, `price_per_gb`, `validity`.
`get_esim`	Details of one plan: data, validity, coverage countries, hotspot, network, provider, local number, link.
`compare_esims`	Compare 2–5 plans side by side (ids from `search_esims`): price, data, validity, price per GB, coverage, network, hotspot, local number — and which has the lowest price, most data, longest validity and lowest price per GB.
`list_countries`	Destinations with plan counts and lowest prices.
`search` / `fetch`	Free-text search and document fetch (ChatGPT deep research format). Understands "unlimited", "daily", "local phone number", "local network", "hotspot", "5G".

All tools are read-only. Prices are in KRW. Results come in 13 languages (lang: ko, en, ja, zh-CN, zh-TW, es, fr, ar, vi, th, id, it, de). The tools never take payment or create orders, and they cannot see your esimoa account (orders, installed eSIMs, remaining data).

Plan cards — in clients that support MCP Apps (Claude, ChatGPT, VS Code and others), search_esims, get_esim and compare_esims results are shown as plan cards (ui://esimoa/plans.html). *View plan* opens the plan page on esimoa.com; the cards make no network requests of their own.

Try asking

"Find an eSIM for a 7-day trip to Japan."
"Find a 3-day eSIM for the USA with a local phone number."
"A 10-day eSIM that works in France, Italy and Spain."
"A 5-day Japan eSIM on a local network with hotspot, under 20,000 KRW."
"Compare unlimited data eSIMs for 5 days in Vietnam."
"Compare the first three plans side by side."

Partners

esimoa partners can add their API key so the links carry their partner code (commission on purchases through the link): send X-API-Key: esk_live_…, or append ?key=esk_live_… to the URL in clients that cannot set headers. Get a key at the esimoa Developer Center.

AI(Claude·ChatGPT·Gemini·Cursor 등)에서 이심모아 여행 eSIM 요금제를 검색·비교하는 MCP 서버입니다. 로그인·키 없이 https://api.esimoa.com/mcp 하나만 넣으면 됩니다.

여행지·기간·데이터·현지 전화번호·로컬망/로밍·여러 나라 동시·예산·핫스팟·5G 로 거를 수 있어요.
마음에 드는 요금제 2~5개를 나란히 비교할 수 있고(compare_esims), Claude·ChatGPT 처럼 MCP Apps 를 지원하는 앱에서는 상품 카드로 보여요.
요금제마다 이심모아 상품 페이지 링크가 나오고, 결제는 이심모아 사이트에서 해요(AI 안에서 결제하지 않아요).
예: "미국 3일, 현지 번호 있는 eSIM 찾아줘", "프랑스·이탈리아·스페인 10일, 세 나라 다 되는 eSIM"
