@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/*.

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: "[email protected]", variation_id: 44941 })
→ returns { order_id, order_token, payment_link_url }.

Claude: "Tap this link to pay: <Stripe URL>. 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"
