## Findings

- **info** The word "credentials" in `a11y_check_url` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The input schema at properties.url.description mentions "credentials".

inputSchema.properties.url.description: "Public http:// or https:// page URL (no credentials, no private/localhost addresses)"
```


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `a11y_check_url`

- The description's first verb is "run": a word for a change.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Run an automated accessibility check (axe-core + Lighthouse) on ONE public http(s) web page and return a score, badge tier, and the most important violations with CSS selectors so you can suggest fixes. Takes up to ~1–2 minutes. Automated checks cannot prove WCAG conformance: 'no automated errors found' still needs manual review. Only public pages are accepted (private/localhost addresses are rejected). (공개 웹 페이지 1개 자동 접근성 검사. 자동 검사는 준수를 증명하지 못하며 수동 확인이 남음.)
```

## Only reads (1)

Looks things up and changes nothing. Claude Code: allow.

### `a11y_get_result`

- The name "a11y_get_result" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch the summary of a previously saved web accessibility check by its result ID (WIA-A11Y-XXXXXXXX), including top violations. Only results of web page checks are returned. (저장된 접근성 검사 결과 요약 조회.)
```
