Common questions

Is Worldcitisim eSIM safe?

It passed 0 of 1 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 on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.2) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

@worldcitisim/mcp-esim

MCP server that lets Claude and other MCP-compatible agents search and buy WorldCitiSim eSIM plans. Wraps https://shop.worldcitisim.com/wp-json/esim/v1/*.

Install

Claude Desktop / Claude Code

claude mcp add --scope user wcs-esim npx -y @worldcitisim/mcp-esim

Or paste into ~/Library/Application Support/Claude/claude_desktop_config.json:

"mcpServers": { "worldcitisim-esim": { "command": "npx", "args": ["-y", "@worldcitisim/mcp-esim"] } } }

Cursor / Windsurf / other MCP clients

Same shape — command: "npx", args: ["-y", "@worldcitisim/mcp-esim"].

ChatGPT Developer Mode

Settings → Developer Mode → Add MCP server → same npx command.

Tools exposed

Tool	Purpose
`esim_search_plans`	Filter catalog by country / region / days / GB. Returns matching plans with their first 5 variations.
`esim_get_plan`	Fetch one plan by slug with all variations.
`esim_create_order`	Create a pending order. `payment_method: "stripe"` (default) returns a Stripe Checkout URL for the user to tap; `payment_method: "btc"` returns an on-chain `btc` block (address + amount + QR) to show the user directly. Both return an `order_token` for polling.
`esim_check_order`	Poll an order's status. Returns activation data (ICCID, QR URL) once payment clears.

Example interaction

User: I'm going to Japan for 10 days, what eSIM should I get?

Claude calls: esim_search_plans({ country: "japan", min_days: 7, max_days: 15 }) → returns matching plans with variations priced and in stock.

Claude picks the best match, presents 2–3 options to the user.

User: the 10GB one

Claude: "Pay by card or Bitcoin?"

User: card

Claude calls: esim_create_order({ email: "user@example.com", variation_id: 44941 }) → returns { order_id, order_token, payment_link_url }.

Claude: "Tap this link to pay: . You'll get the eSIM QR in your email within ~30 seconds."

User pays. Claude optionally polls esim_check_order until status=completed.

For Bitcoin, Claude calls esim_create_order({ ..., payment_method: "btc" }) and gets back a btc block — { address, sats_amount, btc_amount, qr_data_uri, expires_at } — which it shows the user to pay from any on-chain wallet. No redirect. If BTC is declined for a small order during a network-fee spike, the call returns a btc_unavailable error and Claude offers card instead. Either way, esim_check_order polls until status=completed.

Environment

WCS_ESIM_API_BASE — override the API base URL. Default: https://shop.worldcitisim.com/wp-json/esim/v1.

Runtime

Node 20.11+ (for native fetch + ESM).
No secrets. No Stripe credentials touch this process. Payment happens on Stripe's hosted checkout page; the MCP just hands the agent the URL.
Catalog is client-side cached 5 minutes + ETag-aware; multiple search calls within a minute don't hit the network.

Development

npm install

npm run dev # stdio MCP server on this terminal npm run build # compile to dist/

Point a Claude Code session at the local dev build:

claude mcp add wcs-esim-dev node "$(pwd)/dist/index.js"
