Worldcitisim eSIM tools (4, 2 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • esim_check_orderwrite action

    Poll an order's status. Returns `status: pending` while waiting for payment, `status: processing` or `completed` once paid, with `activation` data (ICCID, QR URL, install instructions).

  • esim_create_orderwrite action

    Create a pending order. With `payment_method: "stripe"` (default) you get back a `payment_link_url` — present it to the user to tap and pay on Stripe's hosted page. With `payment_method: "btc"` you get back a `btc` block (on-chain address + amount + QR data URI + expiry) — present the address and amount to the user to pay from any Bitcoin wallet; no redirect. If the user hasn't said how they want

  • esim_get_plan

    Fetch the full detail of one plan by slug, including all variations (every days × GB permutation with its price).

  • esim_search_plans

    Search the Worldcitisim eSIM catalog. Returns plans matching the given filters (country ISO code, region, desired days, desired GB). Plans have variations — each variation is one specific (days × GB × price) combo. The user picks one variation_id to buy.

Install Worldcitisim eSIM in Claude Code, Cursor or VS Code

Runs npx -y @worldcitisim/mcp-esim on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add mcp-esim -- npx -y @worldcitisim/mcp-esim
Add to Cursor

What the publisher says

From the Worldcitisim eSIM repository's README, as published. We do not edit it. Read it on GitHub

@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/claudedesktopconfig.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.

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: <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 esimcreateorder({ ..., paymentmethod: "btc" }) and gets back a btc block — { address, satsamount, btcamount, qrdatauri, expiresat } — 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 btcunavailable error and Claude offers card instead. Either way, esimcheck_order polls until status=completed.

Environment

  • WCSESIMAPI_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"
