Changes things 6Claude Code: ask
  • business_daysBusiness days: is this date a working day in a country (or region) or on a market (TARGET2, NYSE, LSE…), the holiday's name, next and previous business day, date + N business days,…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
    Business days: is this date a working day in a country (or region) or on a market (TARGET2, NYSE, LSE…), the holiday's name, next and previous business day, date + N business days, business days between two dates, a year's holidays. Offline, python-holidays.

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Who registered this domain and when? RDAP from the TLD's own registry (found through IANA's bootstrap): created, updated, expires, age in days, registrar, status, nameservers, DNSSEC. Or registered: false. A TLD without RDAP costs nothing.

    Description, as the server wrote it
    Is this EORI number valid for EU customs? The European Commission's EOS service, up to 10 numbers per call; name and address where the operator consented to publication. A service that is down costs nothing.

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    ECB euro reference rate for any pair on any date since 1999 (the latest ECB day on or before it, named), cross rates through the euro in Decimal, optional amount rounded to the currency's minor units. Reference rate, not a dealing rate.

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

    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
    Is this wallet address or name on a public sanctions list? OFAC SDN (incl. ~500 digital-currency addresses), EU and UK lists — UN designations through them, each hit with its UN number — with each list's date and SHA-256. A lookup, not a compliance determination.

    • 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
    Is this EU VAT number valid today? Asks VIES (the member state's registry): valid, registered name and address, check time. Pass requester_vat (your own EU VAT number) to get VIES's consultation number — official proof of the check in your name. A registry that is down costs nothing.

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.
