## MCP tools (3)

### `check_ico_insolvency` (~80 tokens)

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).

Input parameters:

- `ico` (string, required): Czech IČO — 7 or 8 digits.

### `search_person_insolvency` (~146 tokens)

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.

Input parameters:

- `dob` (string): Date of birth, YYYY-MM-DD. Optional but strongly recommended — common names produce many false positives without DOB.
- `name` (string, required): 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.

### `poll_isir_events` (~107 tokens)

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.

Input parameters:

- `since_id` (integer): Last seen event id. Use 0 to start from the beginning of recorded ISIR history (~2008).
