MCP tools · 4 exposed · ~1,266 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
get_judgment ~150

Pobiera pelne orzeczenie z SAOS po jego numerycznym ID. Zwraca metadane (sygnatura, sad, data, sklad, podstawy prawne), streszczenie (jesli dostepne) oraz pierwsze 2000 znakow tresci. ID orzeczenia pochodzi z wynikow narzedzia 'search' lub 'search_by_case'. Bledy: `missing_arg` (brak id), `not_found` (id poza baza), `upstream_error`.

saos_cite_check ~447

Citator 'czy wyrok zyje': dla podanej sygnatury szuka POZNIEJSZYCH orzeczen, ktore ja cytuja (pelnotekstowo w SAOS), i skanuje ich uzasadnienia pod frazy przelamania linii orzeczniczej (np. 'odstepuje od pogladu wyrazonego', 'nie podziela pogladu', 'traci moc uchwala', 'uchwala skladu siedmiu sedziow') w oknie ~500 znakow wokol wystapienia sygnatury. Werdykt: przelamanie_wykryte / uchwala_skladu_powiekszonego / nadal_cytowany / brak_cytowan_w_saos. To heurystyka - kazde trafienie ma fragment tekstu do recznej weryfikacji, a brak trafien NIE potwierdza aktualnosci orzeczenia. Bledy: `missing_arg` (nieczytelna sygnatura), `invalid_court_type`, `upstream_error`.

NameTypeReqDescription

courtTypestringOpcjonalnie: typ sadu orzeczenia badanego - sygnatury powtarzaja sie miedzy sadami, to doprecyzowuje ktore orzeczenie sprawdzamy.
deepScanbooleanCzy pobierac pelne teksty cytujacych orzeczen (domyslnie true). false = tylko szybki skan snippetow z wyszukiwarki.

Daty bywaja znieksztalcone przez OCR - weryfikuj sygnature i date w zrodle. Przydatny do: analizy linii orzeczniczej, precedensow, wyszukiwania po tresci / sygnatuze / sedzim / podstawie prawnej.
