How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 38 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability71
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 753 tokens (~150/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management73
- Stability observed for 22 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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 →
brutto_na_netto ~168
Ile netto zostaje z podanej kwoty brutto w Polsce: umowa o pracę (z rozbiciem na składki ZUS, zdrowotną i zaliczkę PIT), umowa zlecenie i umowa o dzieło, koszt pracodawcy, ulga dla osób do 26 lat i sumy roczne. Używaj ZAWSZE, zamiast liczyć polski PIT i ZUS samodzielnie.
| Name | Type | Req | Description |
|---|---|---|---|
| brutto | number | yes | Miesięczna kwota brutto w złotych. |
| rok | integer | – | Rocznik podatkowy. Pominięty = rok bieżący. Podawaj tylko, gdy użytkownik wprost pyta o inny rok. |
No output schema declared.
No examples provided.
katalog ~78
Co ten serwis potrafi policzyć: obsługiwane roczniki, zakresy kwot i stawek, wzorce adresów API. Wywołaj, gdy narzędzie zwróci błąd „kwota spoza siatki" albo gdy nie wiesz, który rocznik jest bieżący.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
netto_na_brutto ~148
Odwrotność: jakie wynagrodzenie brutto trzeba wpisać w umowie o pracę, żeby na konto wpływała podana kwota netto. Zwraca też, ile dokładnie netto daje to brutto (netto nie jest ciągłą funkcją brutto, bo zaliczka zaokrągla się do pełnych złotych).
| Name | Type | Req | Description |
|---|---|---|---|
| netto | number | yes | Oczekiwana miesięczna kwota netto w złotych. |
| rok | integer | – | Rocznik podatkowy. Pominięty = rok bieżący. Podawaj tylko, gdy użytkownik wprost pyta o inny rok. |
No output schema declared.
No examples provided.
stawka_godzinowa ~144
Ile netto wychodzi ze stawki godzinowej brutto — na zleceniu (także z dobrowolną chorobową i dla studenta do 26 lat) oraz na etacie. Zwraca stawkę netto za godzinę i kwotę miesięczną.
| Name | Type | Req | Description |
|---|---|---|---|
| rok | integer | – | Rocznik podatkowy. Pominięty = rok bieżący. Podawaj tylko, gdy użytkownik wprost pyta o inny rok. |
| stawka | number | yes | Stawka brutto za godzinę w złotych, np. 33 albo 28.61. |
No output schema declared.
No examples provided.
stawki_roku ~126
Stawki i progi danego rocznika: płaca minimalna (z datami zmian w trakcie roku), minimalna stawka godzinowa, kwota wolna, progi PIT, koszty uzyskania, limit 30-krotności, stopy składek ZUS pracownika i pracodawcy, zdrowotna, PPK. Używaj, zanim zacytujesz którąkolwiek z tych liczb.
