What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

  • get_topup_plans

    Mobile recharge: detects the operator of a mobile number and returns the live recharge and top-up options for it (airtime, data packs and plans): what the recipient receives, validity where it applies, and the price in USD. The number must include the country code, e.g. +91123456

  • list_esim_destinations

    Lists every country and region Slashtel sells travel data eSIMs for (about 200 destinations), returning each destination's code, name, lowest live price in USD and number of plans. Use it to find the destination code when the user names a place, a region such as Europe or Asia, o

  • get_esim_plans

  • create_checkout_link

  • check_esim_status

    For a traveller who already bought a Slashtel eSIM: returns data used, data left, plan size, expiry, status (not yet installed, active, used up or expired) and whether automatic top-up (Keep me connected) is on. Needs the email used at checkout AND the eSIM's ICCID (the long numb

  • check_phone_compatibility

    Explains how the traveller can confirm their own phone supports eSIM and is unlocked before buying, with steps for iPhone and Android. Optionally pass the phone brand to get brand-specific steps. Use it before create_checkout_link when the user is unsure their phone will work; an

  • get_flight_fares

  • get_layover_esim

    For a trip with a connection: finds Slashtel travel eSIM plans that cover the transit hub's country AND the destination country (and an optional second stop) on one QR code, cheapest first, with live prices in USD. Use it when someone flies via Dubai, Doha, Istanbul, Abu Dhabi, S

  • get_flight_status

    Live status of a flight by its number for yesterday, today or tomorrow: departure and arrival airports, scheduled and expected times, terminal, gate and baggage belt, whether it is in the air, its last reported position, and a slashtel.com link to see it live on the map and get a

  • create_price_alert_link

    Returns a slashtel.com link that opens the free flight price alert form with the route filled in. The traveller enters and confirms their own email on the site, then gets an email when the fare drops. Nothing is created until they confirm.

Common questions

Is Slashtel safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 42 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?
