## Tools (as reported by the server, not verified)

- `lookup\_by\_ico`: Get a single Czech company record by its IČO \(8-digit Business ID\). Returns official name, registered address, legal form, VAT ID \(DIČ\), founding date, and trade license activities. Returns null if IČO is not found in ARES.
- `search\_companies`: Search ARES by company name, city, street, PSČ, or NACE code. Combines all filters with AND. Useful when user knows name but not IČO, looking for companies in a building, or all businesses in a sector.
- `search\_by\_address`: Find all companies registered at a given Czech address. Useful for due diligence \(virtual offices, shell companies\), real estate research, or competitor mapping in a building.
- `search\_by\_nace`: Find Czech companies by CZ-NACE activity code \(economic sector classification\). Example: "62" = IT, "47" = retail, "86" = healthcare. Optional city filter. Useful for market research.
- `get\_bank\_accounts`: Get transparent bank accounts published for this company \(only available for VAT-registered subjects\). Useful to verify payment details on an invoice match the company.
- `get\_statutaries`: Get current statutory body \(jednatelé, představenstvo, etc.\) of a Czech company — who can legally act on its behalf. Returns active members only \(with valid zápis, not yet removed\). Essential for due diligence and compliance checks.
- `get\_owners`: Get owners of a Czech company from the Veřejný rejstřík \(public register\) — společníci \(partners of s.r.o./v.o.s./k.s.\) and akcionáři \(shareholders of a.s.\), with their share \(vklad/splaceno/velikost podílu\) exactly as published, including historical members with their date of removal \(datum výmazu\)
- `validate\_dic`: Validate a Czech DIČ \(VAT ID\). Format check: "CZ" + 8-10 digits. For 8-digit tail \(legal entities\) also runs MOD11 checksum against the embedded IČO.
- `check\_vat\_payer`: Check whether a Czech company is a registered VAT payer \(plátce DPH\). If yes, returns DIČ, financial office, and any transparent bank accounts \(payment details\).
- `get\_history`: Get historical record of a company \(previous names, registered address changes, trade license history\). Useful for due diligence.
- `watch\_entity`: Start onboarding for free monitoring of one Czech company by IČO. Stub only — persists nothing yet. Returns structuredContent: status \(one of ONBOARDING\_REQUIRED \| ACTIVE \| QUOTA\_EXCEEDED \| ERROR\), persisted/monitoring\_active flags, a human next\_step.url for onboarding \(the user completes onboarding
