eSIM Tabby is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Screening looks for known threats and hidden instructions at the time of the check, and runs again weekly and whenever the tool list changes. It cannot see the server's code, so only connect what you need and review what Muse asks to do. How screening works.
search_esim_plansFind travel eSIM data plans available for a destination.get_plan_detailsFull details of one eSIM plan, including current price.create_checkoutStart 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 hostpay_orderPay 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 get_order_statusCheck 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_esim_activationGet 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.list_topup_optionsData 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.create_topup_checkoutBuy 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 andget_esim_usageHow much data an active eSIM has used, and how much is left.cancel_orderCancel 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 nlist_my_ordersList this account's eSIM orders, newest first.https://esimtabby.com/mcpNot in Muse's Connectors list yet, but Muse can still use it.
