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. All calculations run on the server with engines that follow current Polish law and are updated every year, so the assistant does not guess rates or thresholds. No account, no personal data - only the parameters of each call are sent. Results are informational, not tax advice.
