## Tools
- 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. Endpoint: https://ares.cz-agents.dev/mcp
- 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. Endpoint: https://ares.cz-agents.dev/mcp
- 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. Endpoint: https://ares.cz-agents.dev/mcp
- 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. Endpoint: https://ares.cz-agents.dev/mcp
- 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. Endpoint: https://ares.cz-agents.dev/mcp
- 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. Endpoint: https://ares.cz-agents.dev/mcp
- 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. Endpoint: https://ares.cz-agents.dev/mcp
- 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). Endpoint: https://ares.cz-agents.dev/mcp
- get_history - Get historical record of a company (previous names, registered address changes, trade license history). Useful for due diligence. Endpoint: https://ares.cz-agents.dev/mcp
