It exposes 3 tools, read directly from the server on our last check. Among them: esim_find_plans, esim_order_status, esim_start_checkout.

Is NUM Travel 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 411 ms. The bar chart above shows every period we have measured.

How do I connect NUM Travel eSIM?

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 NUM Travel eSIM need an API key?

No. NUM Travel eSIM completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is NUM Travel eSIM?

It answers our handshake in 411 ms on average, which is faster than 32% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
