## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Supply Chain Security**: 87/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (98 of 102), so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (98 of 102), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to IsaacEryn/a11ychk).
  - Clear OSI-approved license (Apache-2.0).
  - Actively maintained (last published 0 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 0/100
  - Schema quality not yet verified: we do not have a sandbox capture of the MCP schema this version of the package serves yet.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: we do not have a sandbox capture of the MCP schema this version of the package serves yet.
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: we do not have a sandbox capture of the tool definitions this version of the package serves yet.
- **Capabilities**: 0/100
  - Protocol version not yet verified: we do not have a sandbox capture of the MCP handshake this version of the package performs yet.

**Unverified: 4 categories.** Categories scored 0 because our sandbox run of this package has not given us the schema these checks need to read. That is a gap on our side rather than a finding about the package, and we only credit what we can confirm, so the score stands at 0 until the capture succeeds. We are working through the fleet, so this normally clears without any action from you.

## MCP tools (5)

### `scan_page` (~112 tokens)

페이지 접근성 검사

웹 페이지 1개를 WCAG 2.2 AA + KWCAG 2.2 기준으로 검사한다 (axe-core + 자체 규칙). localhost 개발 서버도 검사할 수 있다. 각 위반에 한국어 개선 가이드(guide)가 붙는다. 사이트 전체 표본 검사·인증 준비 보고서는 a11ychk.com 웹 서비스의 기능이다.

Input parameters:

- `lang` (string): 결과 언어 (기본 ko)
- `url` (string, required): 검사할 페이지 URL

### `scan_pages` (~98 tokens)

여러 페이지 접근성 검사

웹 페이지 여러 개(최대 10개)를 한 번에 검사한다. crawl_sample이 수집한 표본을 넣기 좋다. 그 이상 규모의 사이트 단위 검사는 a11ychk.com에서 표본 수집부터 보고서까지 자동으로 처리한다.

Input parameters:

- `lang` (string): 결과 언어 (기본 ko)
- `urls` (array, required): 검사할 URL 목록 (최대 10개)

### `crawl_sample` (~109 tokens)

대표 페이지 표본 수집

사이트의 sitemap·내부 링크에서 대표 페이지 표본을 뽑는다 (WCAG-EM 방식 층화 표집, robots.txt 존중). 브라우저 없이 동작한다. 결과 URL들을 scan_pages에 넘겨 검사할 수 있다.

Input parameters:

- `lang` (string): 결과 언어 (기본 ko)
- `maxPages` (integer): 표본 크기 (기본 8, 최대 20)
- `url` (string, required): 사이트 루트 URL

### `get_fix_guide` (~97 tokens)

규칙 개선 가이드 조회

검사 규칙(axe/자체 규칙) 하나의 한국어 개선 가이드와 WCAG·KWCAG 매핑을 조회한다. 코드 예시가 포함되어 수정 작업에 바로 쓸 수 있다. 브라우저 불필요.

Input parameters:

- `lang` (string): 결과 언어 (기본 ko)
- `ruleId` (string, required): 규칙 id (예: image-alt, color-contrast)

### `kwcag_checkpoint` (~109 tokens)

KWCAG 검사항목 조회

KWCAG 2.2 검사항목(33개) 하나의 검사 방법·대응 WCAG 성공기준·자동 판정 규칙을 조회한다. id(예: 5.1.1) 또는 슬러그(예: alternative-text)로 찾는다. 브라우저 불필요.

Input parameters:

- `idOrSlug` (string, required): 검사항목 id 또는 슬러그
- `lang` (string): 결과 언어 (기본 ko)
