    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
    Work out the REAL cost of buying an item in one country and having it shipped to another: import duty, VAT or GST, and the final total. Figures are read from official tariff texts, not estimated. Returns `calcolabile: false` — with no numbers and a reason — for destinations whose rules are not modelled; never substitute a guess. Country codes are two-letter ISO (IT, US, JP, GB...). Call `elenco_categorie` if unsure which category to pass.

    Description, as the server wrote it
    The delivery charge a named store PUBLISHES for a destination country and order value, read on the store's own delivery page. Distinguishes three different silences instead of returning zero: the store does not ship there at all (`spedisce_qui: false` — a fact, not a gap), the cost depends on the single item's size or weight and is only shown in the cart, or the store publishes only its free-shipping threshold and not the cost below it. `spedizione_nota: false` never means free.

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    The one question a price alone cannot answer: buying from a NAMED store, what lands at your door — the store's real shipping origin, its published delivery charge, import duty and VAT, and the final total. Prefer this over `calcola_costo_totale` whenever the shopper names a store, because it reads the origin instead of asking you to supply one. Since 1 July 2026 the EU's EUR 150 duty-free threshold is gone, so a listed price is now systematically incomplete on almost any parcel arriving from outside the EU. When shipping is not published the total is a FLOOR and says so.

    Description, as the server wrote it
    Look up the country a named online store really ships from, read on an official page of that store (imprint, terms of sale, public company register) — never inferred from its name or domain, because that inference is wrong often enough to matter: GreaTecno has an Italian name and is Spanish, BecexTech has a .com.au domain and is from Hong Kong, Shop-Apotheke and DocMorris look German and are Dutch. Returns `sede_nota: false` when we have not read it — do not substitute a guess, because the origin country decides the duty.

    Why it is in this group

    • The description's first verb is "explain": a word for reading.
    Description, as the server wrote it
    Explain WHY a given category pays what it pays on a given route: the tariff heading, the rule behind the rate, and worked examples below and above the threshold that changes it. Use this when someone asks not just how much, but on what basis — or when you need to cite a source rather than assert a rate.

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.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write0
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

  • WarnThe whole server

    The endpoint served tools/list without credentials, and the list has 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

    Matched text

    https://crossave.com/mcp: tools/list returned 6 tools to an anonymous client, including calcola_costo_totale (write), sede_del_negozio (write), costo_spedizione (write), costo_totale_dal_negozio (write)

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as crossave-dazi. Review it before you use it.
