Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

deposit

create_deposit

Open a top-up of the wallet and get what is needed to pay it. Floors: $10 for a wallet's first deposit, $1 after that; cap $1000 per deposit. Crypto deposits earn a bonus (+2% from $25, +3% from $50, +5% from $100, capped at $25); every purchase returns 3% cashback. With payment_method "crypto" pass a currency from: BTC, ETH, TRX, USDTTRC, USDTETH, USDTBSC — the answer then carries `pay`: the address, the exact amount in the coin (network fee included) and expires_at (about 15 minutes; after that open a new deposit). Send exactly `pay.amount` to `pay.address` on `pay.network`, then poll get_deposit(token) until status is paid. checkout_url is the hosted pay page for a person; card deposits have only that. Needs the wallet code.

get_deposit

One deposit of the wallet by its token: status pending → paid (credited, bonus included) | underpaid (nothing credited yet, the rest can still arrive) | payment_held (the payment processor's compliance check stopped the payment and holds it: nothing is credited, do not pay again, the person should write to support) | expired. Poll every ~30 s after sending; crypto needs the network's confirmations. Needs the wallet code.

wallet

create_wallet

Mint a prepaid wallet with no account behind it and get its secret ONCE: `code` (32 hex characters) and the same secret as a 12-word `phrase`. Save the code before doing anything else and send it as `Authorization: Bearer <code>` on every wallet call; there is no recovery and no identity to prove. The balance is spent on eSIMs (retail price, cashback on every purchase) and never paid back out. accept_terms must be true (https://esimker.com/terms). Then create_deposit to fund it. Rate-limited and geo-blocked like checkout.

get_wallet

The wallet behind the code: ref (a public handle for support), balance_usd, cashback_percent, the deposit rules that apply to it now (min_usd, max_usd, first, bonus tiers), the last 50 transactions, orders (with their tokens — the wallet is where a buyer's order links are kept) and deposits. Needs the wallet code.

checkout

create_checkout

Create an order for a person to pay. Returns token, checkout_url (the gateway's page: hand it to the person) and order_url (the order page in `lang`, with the QR code once paid: show it to the buyer only, the token is a secret). Confirm the plan and the price first: every call creates a new unpaid order, so do not retry while a checkout is open. `email` (optional) also gets the eSIM by mail. `period_num` (1–365) only for daily_unlimited plans. `topup_iccid` with a plan_id from list_topups tops up an existing eSIM. A 403 means the caller's jurisdiction is embargoed. To pay from a wallet use purchase_esim.

destinations

search_destinations

Destinations on sale. `query` matches the name in any of 18 languages, the slug or the ISO code; empty lists everything. Each item: dest_code, slug, name, min_retail (USD, the cheapest fixed plan), unlimited_from (USD per day of a Daily Unlimited pass, or null), plan_count. Continue with get_plans(slug).

order

get_order

An order by its token. status goes pending (unpaid) → paid → provisioning → ready; also expired, underpaid, failed_provisioning, gift_waiting, and payment_held — the payment processor's compliance check stopped the payment and holds the money: nothing is issued, the person must not pay again and should write to support. When ready, esim.activation_code is the LPA string (render it as a QR code), with iccid, smdp and matching_id. After payment poll every ~10 s; delivery usually takes under a minute.

payment

get_payment_methods

Checkout methods open right now: "crypto" (a hosted invoice: BTC, ETH, TRX, USDT), "card", and "wallet" (a prepaid balance, see create_wallet). `gateways` names the providers behind each method; a checkout that does not ask for one by name goes to the first, which is what these tools do.

plans

get_plans

The plans of one destination (slug from search_destinations). Each plan: id (the plan_id for an order), name, gb, days, retail (USD; per day when daily_unlimited is true), daily_unlimited, location_codes (the countries it covers), networks, speed, supports_topup. Also the published rating.

purchase

purchase_esim

Charge the wallet and issue an eSIM, no checkout. `client_ref` (1–64 chars) is your own reference for this purchase and makes the call idempotent: a retry with the same value returns the existing order without a second charge, so reuse it after a timeout and never invent a new one for the same purchase. `period_num` (1–365, default 7) only for daily_unlimited plans; the charge is price × days. `topup_iccid` with a plan_id from list_topups tops up an eSIM. Returns the order (status paid) with order_url; poll get_order(token) for ready and the activation code. A 402 is a short balance: create_deposit first. A wallet pays for at most 50 orders in 24 hours (429 beyond that; a retry answered from client_ref does not count). Needs the wallet code.

topups

list_topups

Top-up plans that fit an eSIM we issued: plan_id, name, gb, days, retail. Order one with create_checkout(plan_id, topup_iccid=iccid) or, from a wallet, purchase_esim(plan_id, client_ref, topup_iccid=iccid).

usage

get_usage

Remaining data and status of an eSIM we issued.

Answers built from our own checks of this server.

What can esimker eSIM store do?

It exposes 12 tools, read directly from the server on our last check. Among them: create_checkout, create_deposit, create_wallet, get_deposit, get_order, get_payment_methods and 6 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is esimker eSIM store mostly used for?

Its tools cluster around deposit and wallet. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is esimker eSIM store working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 300 ms. The bar chart above shows every period we have measured.

How do I connect esimker eSIM store?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does esimker eSIM store need an API key?

No. esimker eSIM store completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 12 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is esimker eSIM store?

It answers our handshake in 300 ms on average, which is faster than 47% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
