Available tools 5

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

esim

search_esim_plans

Find e-eSIM eSIM plans for one destination or several (countries or regions, any language). Returns the best-value plans first with full facts, coverage lists and a direct link; multi-country plans that include the destination are returned too and marked covers_via. Use when a user wants mobile data abroad; use recommend_plan when they describe a whole trip.

plan

get_plan_details

Full facts for one e-eSIM plan by product id: coverage list, data and speed rules (daily allowance, reduced speed, fair use), validity clock, expiry date, notice, carrier, price, reviews and link — quoted in the customer's bucket or currency when given.

recommend

recommend_plan

Turn a trip into up to three plan recommendations: countries (1-5, any language), number of days and how much data the traveller uses. Each fit carries the full plan facts, the total price for the whole trip and a one-sentence reason built only from catalogue facts. Use this first whenever the user describes a trip rather than asks for a list.

shop

get_shop_facts

How e-eSIM works, in the shop's own words: delivery and installation, device requirements, payment methods, refund policy, no top-ups, hotspot, Usage Dashboard and apps, support and company details. Use for any "how / when / what if" question that is not about one specific plan.

start

start_checkout

Hand the customer to the e-eSIM shop to buy one plan. Returns buy_url (the product page where they tap Buy now and pay securely — card, Apple Pay, Google Pay, PayPal, Amazon Pay, Klarna or a local method such as iDEAL | Wero, Bancontact, BLIK or Pix; there is no discount-code field) plus the plan name and price in the customer's bucket or currency. No account needed; the eSIM is emailed right after payment. There is no in-chat order tracking.

e-eSIM Catalog — questions

Answers built from our own checks of this server.

What can e-eSIM Catalog do?

It exposes 5 tools, read directly from the server on our last check. Among them: get_plan_details, get_shop_facts, recommend_plan, search_esim_plans, start_checkout. 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 e-eSIM Catalog working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 338 ms. The bar chart above shows every period we have measured.

How do I connect e-eSIM Catalog?

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 e-eSIM Catalog need an API key?

No. e-eSIM Catalog completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is e-eSIM Catalog?

It answers our handshake in 338 ms on average, which is faster than 42% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
