MCP support
The remote MCP server exposes public plan search, coverage, checkout, and order tools, plus OAuth-protected account and top-up tools. It uses streamable HTTP and requires no API key.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

Details
From the project READMEHungry eSIM — MCP Server
Buy and manage travel eSIMs from AI assistants like Claude, Cursor, and VS Code via the Model Context Protocol.
Endpoint: https://api.hungry-esim.com/mcp (remote, streamable HTTP — no install, no API key)
Unlimited data plans where you pick your days, top-ups for eSIMs you already own, and plain credit-card checkout on hungry-esim.com. No crypto wallet, no prepaid balance, no API key required.
This repository is the public home of the server: docs, manifest, and setup guides. The server itself is a hosted remote service.
What you can do
| Tool | What it does | Auth |
|---|---|---|
search_esim_plans | Search travel eSIM data plans by destination, data amount, and validity | — |
check_destination_coverage | "Does it work in …?" — coverage check for a destination with representative plans | — |
find_cheapest_plan | Cheapest plan(s) for a destination and trip length (total-trip cost ranking) | — |
get_plan_details | Full details for one plan (coverage, speed, top-up support) | — |
create_checkout | Create a card checkout link for a plan — for unlimited plans, choose how many days | — |
get_order_status | Check an order and eSIM installation status | — |
my_esims | List eSIMs on your account with status and usage | OAuth |
my_orders | List your past orders | OAuth |
list_esim_topups | Top-up options for an eSIM you already own | OAuth |
topup_esim | Buy a top-up for an existing eSIM — no new QR code needed | OAuth |
Public tools work immediately with no sign-in. Account tools use OAuth: the assistant sends you to hungry-esim.com to sign in once, then can see your eSIMs and orders.
Payment always happens on hungry-esim.com in a normal browser checkout with a credit card. The assistant never touches your payment details.
Setup
Claude (claude.ai / Claude Desktop)
Settings → Connectors → Add custom connector → paste:
https://api.hungry-esim.com/mcp
Cursor
Add to ~/.cursor/mcp.json:
{
"mcpServers": {
"hungry-esim": {
"url": "https://api.hungry-esim.com/mcp"
}
}
}
VS Code (GitHub Copilot)
Add to your mcp.json (Command Palette → “MCP: Add Server” → HTTP):
{
"servers": {
"hungry-esim": {
"type": "http",
"url": "https://api.hungry-esim.com/mcp"
}
}
}
Then ask things like:
- “I’m going to Japan for 10 days — find me an eSIM with unlimited data.”
- “What’s the cheapest data plan for France?”
- “Top up the eSIM I bought last month.”

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
