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

esim
get_esim_plan
Fetch full details of a single Siima eSIM plan by its id (from search_esim_plans). To buy: call create_checkout_link with the plan id, give the returned URL to the user. After payment the eSIM (QR code + activation link + manual codes) is emailed to them automatically — no account needed.
search_esim_plans
Search prepaid travel eSIM data plans by destination country (ISO 3166-1 alpha-2, e.g. "JP"), region (e.g. "Europe"), minimum data in GB, maximum total price, or plan duration in days. Returned price is the final amount the customer pays at checkout (all fees included), in the requested currency. To buy: call create_checkout_link with the plan id, give the returned URL to the user. After payment the eSIM (QR code + activation link + manual codes) is emailed to them automatically — no account needed.
checkout
create_checkout_link
Create a secure payment link on siima.io for a Siima eSIM plan (Stripe-powered, but hosted on our own site — never a redirect to checkout.stripe.com). Give the returned url to the user to complete payment. Optionally pass the buyer's email so the link goes straight to the payment page; otherwise the page collects it first. After payment, the eSIM QR code, one-tap activation link, and manual installation codes are emailed to the buyer within a minute. No account or signup is required.
destinations
list_destinations
List all countries Siima has eSIM plans for, with plan counts and the cheapest total price per country. Country codes are ISO 3166-1 alpha-2.

Siima eSIM — questions

Answers built from our own checks of this server.

What can Siima eSIM do?
It exposes 4 tools, read directly from the server on our last check. Among them: create_checkout_link, get_esim_plan, list_destinations, search_esim_plans. 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 →
Is Siima eSIM 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 231 ms. The bar chart above shows every period we have measured.
How do I connect Siima eSIM?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Siima eSIM need an API key?
No. Siima eSIM completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Siima eSIM?
It answers our handshake in 231 ms on average, which is faster than 57% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
