Changes things 2Claude Code: ask
  • check_ico_insolvencyCheck whether a Czech company (by IČO) has any active insolvency proceeding in ISIR.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
    Check whether a Czech company (by IČO) has any active insolvency proceeding in ISIR. Returns spisová značka, start date, and current phase if found. Returns "no record" if not (which is also informative).

    Annotations the server declares

    • title: Check IČO Insolvency in ISIR
    • readOnlyHint: true
    • openWorldHint: true
  • poll_isir_eventsPull a batch of recent ISIR events (insolvency register publications) since the given event id.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
    Pull a batch of recent ISIR events (insolvency register publications) since the given event id. ISIR is an append-only feed — each call returns up to ~1000 events newer than `since_id`. Use `last_id` from response as next `since_id`. Useful for compliance monitoring or to back-fill an index.

    Annotations the server declares

    • title: Poll ISIR Event Feed
    • readOnlyHint: true
    • openWorldHint: true
Only reads 1Claude Code: allow
  • search_person_insolvencySearch ISIR for an individual person (FO) by name and optional date of birth.No findings

    Why it is in this group

    • The name "search_person_insolvency" says "search": a word for reading.
    Description, as the server wrote it
    Search ISIR for an individual person (FO) by name and optional date of birth. Returns active insolvency proceedings (oddlužení / osobní bankrot). Used to screen statutory persons in KYC and DD workflows.

    Annotations the server declares

    • title: Search Person Insolvency in ISIR
    • 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.
