eSIM Tabby MCP server

• cancel_orderwrite actionFree

  Cancel an order and refund it. Only possible while the eSIM is uninstalled. Once the profile has been installed on a device the provider refuses to take it back, and this returns an error instead — send the user to support. Card payments refund automatically. A USDC payment has no on-chain refund rail, so the order becomes `refund_pending` and support returns the money by hand.

• create_checkoutwrite actionFree

  Start a purchase — the step after the user picks a plan from search_esim_plans. Call it with that plan's plan_id (get_plan_details shows the current price first). Returns an order_id and where to pay, on the rail you asked for: 'card' (the default) returns a checkout_url — a hosted Stripe page for a human to open in a browser; once they say they've paid, call get_order_status to confirm and carry on to the QR code. 'x402' returns an x402_url for a wallet to settle in USDC, with no browser step — only choose it if you actually hold a wallet. Never accepts payment details — a card is entered on the hosted page, and a wallet signs for itself. Calling it again for the same plan reuses the pending order (reused: true) instead of creating a duplicate.

• create_topup_checkoutwrite actionFree

  Buy more data for an eSIM the user already has — the step after list_topup_options. Call it with the order_id of the fulfilled eSIM and a plan_id chosen from list_topup_options. The top-up lands on the existing eSIM: same QR code, nothing to re-install. Returns a new order_id and where to pay, exactly like create_checkout: 'card' returns a checkout_url for a human to open, confirmed via get_order_status; 'x402' returns an x402_url for a wallet to settle in USDC. Never accepts payment details — a card is entered on the hosted page, and a wallet signs for itself.

• get_esim_activationFree

  Get the QR code and activation details for a purchased eSIM. Not read-only: like get_order_status, an order that is not ready yet is advanced first, so this can change the order's state.

• get_esim_usageFree

  How much data an active eSIM has used, and how much is left.

• get_order_statuswrite actionFree

  Check an order. Call this after the user says they've paid. Not read-only: an order still in progress is advanced first — payment is confirmed and the provider order placed or collected — so the status can change as a result of calling this.

• get_plan_detailsFree

  Full details of one eSIM plan, including current price.

• list_my_ordersFree

  List this account's eSIM orders, newest first.

• list_topup_optionsFree

  Data top-ups that can be added to an eSIM the user already has. A top-up extends the existing eSIM — same QR code, nothing to re-install. Not every plan is reloadable; this returns an empty list when none apply.

• pay_orderwrite actionFree

  Pay for an order in USDC over x402, without opening a browser. Only for an MCP client that signs x402 payments itself: call it once for the payment requirements, then repeat the call carrying the signed payment in _meta['x402/payment'] and it settles and starts the eSIM. If your wallet is a separate tool, make an x402 request to the order's x402_url instead — this tool cannot take a payment on a wallet tool's behalf.

• search_esim_plansFree

  Find travel eSIM data plans available for a destination.
