Polish payroll, tax and public-registry tools from cash-service.pl, exposed as 17 read-only MCP tools. Calculators: net-from-gross salary (employment contract), civil contracts (zlecenie, dzieło), B2B vs employment comparison, ZUS and health-insurance contributions for sole traders, ZUS stages for a new business, loan instalments, tax late-payment interest. Registries: company lookup by NIP on the Ministry of Finance VAT whitelist (status, bank accounts), Polish bank account number validation (NRB/IBAN) with bank name, competent tax office / district court / bailiff for an address, postal codes, NBP exchange rates and yearly ZUS/PIT indicators.
