Changes things 2Claude Code: ask
  • check_deviceWhether a phone model supports eSIM, from the models eSIMpass documents (Apple, Samsung, Google).No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Whether a phone model supports eSIM, from the models eSIMpass documents (Apple, Samsung, Google). The phone must also be carrier-unlocked; a model not in the list is not necessarily incompatible.

  • fetchOne destination as a document: plans, live prices and a checkout link per plan.No findings

    Why it is in this group

    • The name "fetch" says "fetch": a word for reading.
    Description, as the server wrote it
    One destination as a document: plans, live prices and a checkout link per plan. The id comes from search.

    Why it is in this group

    • The name "get_esim_install" says "get": a word for reading.
    Description, as the server wrote it
    After the traveller has paid: one-tap install links for their eSIM, for iPhone (iOS 17.4+) and Android (10+), plus the manual-entry codes. Takes the private eSIM link from the traveller's order confirmation page (https://www.esimpass.com/…/my-esim/…); any other value is refused. Each install link installs the eSIM when opened on the phone that will use it. The result is that traveller's private eSIM details.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false

    Why it is in this group

    • The name "get_plans" says "get": a word for reading.
    Description, as the server wrote it
    The plans on sale for one destination right now, with live prices, data, validity and the product page URL. For a regional plan it also lists every country covered; a country missing from that list is not covered. Prices and plans change, so these are the current ones.

    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false

    Why it is in this group

    • The name "search_destinations" says "search": a word for reading.
    Description, as the server wrote it
    Find the eSIMpass travel eSIM for a place: a country ("Japan"), a region ("Europe", "Asia", "Global") or a city ("Tokyo", which is covered by its country's plans). Returns matching destinations with the slug that get_plans and create_checkout_link take.

    • readOnlyHint: true

    • openWorldHint: false

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
