Changes things 1Claude Code: ask
  • sanctions_screen_nameDoes this person or entity name (Latin or Japanese) appear on the Japan MOF asset-freeze list under the Foreign Exchange Act?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
    Does this person or entity name (Latin or Japanese) appear on the Japan MOF asset-freeze list under the Foreign Exchange Act? Returns exact_match, candidates (similar names, not matches), no_match_in_checked_list or unknown (stale/unavailable), with entry ids, all name forms, program, notice dates, list version, freshness and attribution. Reference relay only: not a compliance determination or a statement that a transaction is permitted.

  • get_receiptRe-fetch the stored result of a settled paid call by its receipt_id, for when the response was lost after payment.No findings

    Why it is in this group

    • The name "get_receipt" says "get": a word for reading.
    Description, as the server wrote it
    Re-fetch the stored result of a settled paid call by its receipt_id, for when the response was lost after payment. Free. Unknown or unsettled receipt ids return RECEIPT_NOT_FOUND. Results are kept for 90 days after settlement.

    Annotations the server declares

  • sanctions_list_changesWhat was added to, removed from or modified in the Japan MOF asset-freeze list since a date?No findings

    Why it is in this group

    • The name "sanctions_list_changes" says "list": a word for reading.
    Description, as the server wrote it
    What was added to, removed from or modified in the Japan MOF asset-freeze list since a date? From this service's own record of list versions (MOF publishes only the current list). Each change has the entry id, names, program, before/after fields and the versions compared. History starts at tracking_since; nothing earlier was observed. Free window: last 30 days (an earlier since is clamped; see history_window). Reference relay only.

    Annotations the server declares

    • readOnlyHint: true
    • openWorldHint: true

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.
