The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
check_ico_insolvency ~80
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).
| Name | Type | Req | Description |
|---|---|---|---|
| ico | string | yes | Czech IČO — 7 or 8 digits. |
No output schema declared.
No examples provided.
poll_isir_events ~107
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.
| Name | Type | Req | Description |
|---|---|---|---|
| since_id | integer | – | Last seen event id. Use 0 to start from the beginning of recorded ISIR history (~2008). |
No output schema declared.
No examples provided.
search_person_insolvency ~146
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.
| Name | Type | Req | Description |
|---|---|---|---|
| dob | string | – | Date of birth, YYYY-MM-DD. Optional but strongly recommended — common names produce many false positives without DOB. |
| name | string | yes | Full name in any case (Czech diacritics tolerated). E.g. "Pavel Novák" or "Jana Svobodová". |
| only_active | boolean | – | When true (default), return only currently active proceedings. False also returns closed/dismissed. |
No output schema declared.
No examples provided.
