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.
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. The tools never take payment or create orders, and they cannot see your esimoa account (orders, installed eSIMs, remaining data).

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."

• "Compare unlimited data eSIMs for 5 days in Vietnam."

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.
• 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"
