eSIM Tabby is an MCP server with 11 tools an agent can call, among them cancel_order, create_checkout, create_topup_checkout. It answers at https://esimtabby.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
Buy and manage travel eSIM data plans in the conversation. Pay by card (Stripe) or USDC over x402.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
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 re Inputs: order_id |
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 Inputs: plan_id, pay_with |
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 t Inputs: order_id, plan_id, pay_with |
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. Inputs: order_id |
get_esim_usage | How much data an active eSIM has used, and how much is left. Inputs: order_id |
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 Inputs: order_id |
get_plan_details | Full details of one eSIM plan, including current price. Inputs: plan_id |
list_my_orders | List this account's eSIM orders, newest first. |
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. Inputs: order_id |
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 Inputs: order_id |
search_esim_plans | Find travel eSIM data plans available for a destination. Inputs: country, min_data_mb, max_duration_days |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://esimtabby.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
