Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| audit_htmlA | Runs axe-core against an HTML string (via jsdom) and returns WCAG violations. Catches structural/semantic issues (missing alt text, unlabeled inputs, missing lang/title, empty link text, etc.) — layout-dependent rules like color-contrast are not reliable in jsdom. |
| audit_fileB | Same checks as audit_html, reading the document from a local file path. |
| audit_url | Fetches a URL and audits the raw response HTML — this does not execute client-side JavaScript, so client-rendered SPAs will show as empty. Best for server-rendered pages and static sites. |

Scored across 2 tools
The two tools are clearly distinguished by input source (HTML string vs file path), but their core functionality is identical, which could cause minor confusion about which to use.
Both tools follow a consistent '_audit_' prefix pattern, making their purpose and variation (input type) predictable.
With only two tools, the server feels thin for a full accessibility auditing server, though it narrowly covers its stated input methods.
The server lacks features like rule configuration, output filtering, or detailed reporting, leaving significant gaps for practical usage beyond basic checks.
