## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `scan_accessibility`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user wants a public website or web page checked for accessibility (WCAG 2.1/2.2 AA, ADA, EAA, Section 508): it loads the live page in a real browser, runs axe-core on it and up to two more same-site pages, and returns a 0-100 score, a letter grade and the failing rules with example elements. Takes 15-40 seconds. Do not use it for pages that need a login, for localhost or private-network addresses, or for pasted HTML.
```

## Only reads (1)

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

### `explain_accessibility_issue`

- The name "explain_accessibility_issue" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this when the user asks what an axe-core accessibility rule means or how to fix it — typically a ruleId returned by scan_accessibility, such as color-contrast, image-alt, label or link-name. Returns plain-English steps and a code example. Do not use it to scan a site; use scan_accessibility for that.
```
