Call this server's tools from your browser. Nothing to install.
Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.
Tool list from our last check. Connect live to refresh it.
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.
order_id of the order to cancel

}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.
| Argument | Type | Description |
|---|---|---|
| plan_id* | string | plan_id from search_esim_plans |
| pay_with | string | How the buyer intends to pay. 'card' returns a hosted checkout link for a human to open in a browser. 'x402' returns an x402_url for a wallet tool to settle in USDC, with no browser step — only choose it if you have a wallet. An order keeps the rail it was first given: to pay an existing card order in USDC instead, cancel it and start a new one, so there are never two live ways to pay it. |

}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 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.

}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.

}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.
| Argument | Type | Description |
|---|---|---|

}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.
