eSIM Genius connector for Claude

Last updated 2026-11-10

The eSIM Genius connector lets Claude search our live eSIM plans while you plan a trip. Ask for an eSIM for your destination and Claude can compare plans, check that your phone supports eSIM, and give you a link that opens our checkout with the plan you picked. You pay on esimgenius.ai, never in the chat.

Server URL

https://esimgenius.ai/api/mcp

A remote MCP server over Streamable HTTP. No sign-in and no API key: it only reads our public catalog.

Add it to Claude

  1. In Claude, go to Customize > Connectors and choose Add custom connector.
  2. Name it eSIM Genius and paste the server URL above. If Claude asks how people sign in, choose No sign-in.
  3. Select Add.
  4. In a chat, open + > Connectors and turn eSIM Genius on.

On a Team or Enterprise plan, an Owner adds it for the organization under Organization settings > Connectors (Add, then Custom). The Free plan allows one custom connector. Other MCP clients that support remote servers can use the same URL.

What it can do

  • Search eSIM plans (search_esim_plans): Finds plans for a country, a region (Europe, Asia, Africa, Middle East, Global) or a multi-country trip, filtered by trip length and data, with the countries each plan covers and a link to buy it.
  • Get eSIM plan details (get_plan_details): Shows one plan in full: every covered country, local networks, validity, price and phone requirements.
  • Check phone eSIM support (check_phone_esim): Says whether a phone model supports eSIM, and how to confirm it on the phone itself.
  • List eSIM destinations (list_destinations): Lists every country and region we sell, with the lowest price for each.

Every tool only reads. Plans are data-only (no phone number, calls or SMS), and validity starts when the eSIM first connects to a network in any country the plan covers.

Try asking

  • “Find me an eSIM for Turkey for 2 weeks.”
  • “I am visiting France, Italy and Spain for 10 days. Which eSIM covers all three?”
  • “Does the Samsung Galaxy A55 support eSIM?”
  • “What does the cheapest Japan plan with at least 10 GB cost in euros?”
  • “Which regions does eSIM Genius sell plans for?”

Buying

Each plan comes with a link to esimgenius.ai. It opens our checkout with that plan: you sign in (Google, Apple or an email code) and pay there. Claude never sees your payment details. Prices in the chat are in US dollars unless you ask for another currency; checkout shows the final price in your currency.

Privacy

The connector needs no login and collects no personal data. It receives only what Claude sends to a tool: a destination, trip length, data amount, currency or phone model. It stores no IP address and no conversation content: its log line holds the tool name, the destination or phone model asked about, the number of results and which assistant called. Logs are deleted automatically within 30 days. A purchase on esimgenius.ai is covered by our Privacy Policy.
