Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (7)

`check_risk_flags`read-only	Compliance red-flag check for a Polish company (legal entity) by NIP. USE THIS for KYC/AML or before onboarding a counterparty: returns whether the company appears on Polish or EU sanctions lists (as the sanctioned subject) and whether it has a public warning from the KNF (Polish Financial Supervision Authority). A KNF warning is a notice filed with the prosecutor, not a conviction: apply the presumption of innocence. Legal entities only (sole traders are out of scope). Exact match on NIP/KRS/REGON. Read-only.
`check_vat_whitelist`read-only	Check a Polish company's VAT status in the Ministry of Finance taxpayer register (the 'white list', biała lista KAS) and, optionally, whether a given bank account number is registered to that company. USE THIS before paying an invoice: in Poland, paying over PLN 15,000 to an account outside the white list has tax consequences. Returns VAT status and account-match result. Live query to the official KAS register. Read-only.
`get_company`read-only	Get the full registry profile of a Polish company by its NIP (10-digit tax ID). USE THIS when the user gives a NIP and wants company details, address, board members, or registry status. Returns address, legal form, status, KRS, REGON, PKD activity codes, board members (names from the public KRS register) and VAT status. Data from KRS, REGON and CEIDG public registers. Read-only.
`get_financials`read-only	Get yearly financial statements of a Polish company by NIP, as filed with the National Court Register (KRS). USE THIS when the user asks about a company's revenue, profit, assets or financial results. Returns per-year revenue, net profit, total assets, equity and liabilities. Data from financial statements (RDF/KRS). Read-only.
`get_lei`read-only	Get the Legal Entity Identifier (LEI, ISO 17442) of a Polish company (legal entity) by NIP, from the GLEIF register. USE THIS when the user needs a company's LEI for cross-border or financial-market reporting (MiFID, EMIR, payments). Returns the LEI, the registered legal name and the LEI status. Coverage is partial. Legal entities only. Read-only.
`get_public_tenders`read-only	Get Polish public-procurement contracts awarded to a company (legal entity) by NIP, as published in the Public Procurement Bulletin (BZP). USE THIS for due diligence or sales intelligence when the user asks what public tenders or government contracts a company has won. Returns up to 25 most recent awards (subject, contracting authority, city, date, value) plus the total count and total value across all awards. Legal entities only. Read-only.
`search_company`read-only	Search Polish companies by name (fuzzy match). USE THIS when the user asks to find a Polish company, look up a firm by name, or get its NIP/KRS/REGON. Returns NIP, KRS, city, status and a profile URL. Data from the Polish court (KRS) and statistical (REGON) registers. Read-only.
