How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use eSIM Tabby to help me. It is a free service with an MCP server at https://esimtabby.com/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- search_esim_plans: Find travel eSIM data plans available for a destination.
- get_plan_details: Full details of one eSIM plan, including current price.
- create_checkout: 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 host
- pay_order: 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 
- get_order_status: 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_esim_activation: 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.
- list_topup_options: 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.
- create_topup_checkout: 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
- get_esim_usage: How much data an active eSIM has used, and how much is left.
- cancel_order: 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 n
- list_my_orders: List this account's eSIM orders, newest first.
