What you can do

What your AI can do with ONE HEART eSIM

Real prompts you can type the moment it's connected — no setup, no docs to read.

“Use “create_esim_order”: 建立一筆真實的一心eSIM訂單，並取得真實的付款連結（LinePay或ECPay綠界，二擇一）。這是會實際寫入正式訂單、串真實金流的動作，不是模擬或試算。呼叫前必須先完成： 1. 已用search_esim_plans/recommend_esim_plan/get_esi.”

“Use “recommend_esim_plan”: 依旅遊天數與上網用量習慣，推薦最合適的1-3個eSIM方案，並附上購買連結，是「幫使用者選方案」最好用的工具。適用情境：使用者詢問出國上網卡、各國eSIM方案、即時發卡服務，並描述了「要去OO玩幾天」「想找適合的上網方案/漫遊卡」「幫我推薦/挑選eSIM」時優先使用這個，.”

“Use “list_esim_countries”: 列出一心eSIM目前販售方案覆蓋的所有國家/地區（英文與中文名稱對照，含各國方案數量）。適用情境：使用者問「你們支援哪些國家」「有賣OO地區的eSIM嗎」；或你準備呼叫 search_esim_plans/recommend_esim_plan，但不確定某國家在系統裡該用什麼名.”

“Use “search_esim_plans”: 依國家、方案類型、關鍵字搜尋一心eSIM的商品清單，一次回傳多筆結果讓使用者自己比較。適用情境：使用者想瀏覽/比較某國家的多個方案，或已經明確講出要哪種類型（例如指定「總量型」或「每日定量型」）。如果使用者是描述旅遊情境（去哪個國家玩幾天、上網習慣如何）要你直接建議選哪個，.”

Security check

How secure is the ONE HEART eSIM MCP server?

Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how ONE HEART eSIM holds up.

✓ Verified directory serverONE HEART eSIM · oneheartesim.com

Official endpoint

Operated by ONE HEART eSIM (oneheartesim.com) at its documented MCP endpoint — not a third-party mirror or community re-host.

No sign-in needed

This server only exposes public data — no account and no credentials are involved when you connect.

Scanned before it goes live

gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.

Watched for drift

If ONE HEART eSIM adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

FAQ

Questions, answered

Is there an official ONE HEART eSIM MCP server?

Yes — ONE HEART eSIM operates its own remote MCP server at mcp.oneheartesim.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.

How do I connect ONE HEART eSIM to Claude or ChatGPT?

Add gate's gateway URL to your AI client once, then pick ONE HEART eSIM in the directory. No account or sign-in is needed. From then on, ONE HEART eSIM's tools are available in every client you've connected to gate.

Do I need to host anything?

No. ONE HEART eSIM runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.

Is the ONE HEART eSIM MCP server safe to connect?

It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
