# esimoa MCP — travel eSIM comparison for AI assistants Search and compare travel eSIM data plans from **[esimoa](https://www.esimoa.com)** inside Claude, ChatGPT, Gemini, Cursor and any MCP client: filter by country, trip length, data, local phone number, local or roaming network, several countries at once, budget, hotspot and 5G. Each plan comes with a link to its page on esimoa.com, where you review and buy it. ``` https://api.esimoa.com/mcp ``` Remote server · Streamable HTTP · **no sign-in, no API key needed** · MCP protocol 2024-11-05 to 2026-07-28 · listed in the [official MCP Registry](https://registry.modelcontextprotocol.io) as `com.esimoa/esim`.

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](https://modelcontextprotocol.io/extensions/apps/overview) (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.
