Discoverability

Can agents find your site and its capabilities?

failWebMCP / agent-protocol tools discoveredAgent manifests

The page registers no tools via the WebMCP browser API (navigator.modelContext).

Fix: Expose your actions to AI agents with the WebMCP browser API: register tools via navigator.modelContext.registerTool. Optionally also publish a /.well-known/webmcp.json tool catalog as a discovery signpost.

warnAGENTS.md operating guide for agentsAgent manifests

Found /.well-known/agents.md but it is served as "text/html", not Markdown.

Fix: Serve AGENTS.md as Markdown (text/markdown). See agents.md.

pass/llms.txt guide for AI agentsAgent manifests

Found https://hyundai.com/llms.txt.

pass/llms.txt lists key pages as markdown linksAgent manifests

Found at least one "[name](url)" markdown link.

pass/llms.txt has a summary blockquoteAgent manifests

Found a "> summary" blockquote.

pass/llms.txt opens with an H1 titleAgent manifests

First line is a top-level "# Title" heading.

passKey pages discoveredKey pages crawl

Crawled 12 of 12 discovered pages beyond the homepage.

infoWebsite platformplatform

Could not identify a known website platform (custom stack or unrecognised).

Understanding

Can agents understand your content?

failSingle H1 on homepageStructured data & HTML

No <h1> tag found on the homepage.

Fix: Add exactly one <h1> that names the page. AI summarisers use it as the document title.

warnMarkdown content negotiationOpen agent protocols

Homepage ignored Accept: text/markdown and returned HTML.

Fix: Serve a markdown version of high-value pages when the client asks for text/markdown. AI summarisers, chatbots and IDE agents prefer markdown — fewer tokens, no DOM noise.

warnImages have explicit dimensionsStructured data & HTML

23/25 images have explicit width+height.

Fix: Add width and height to every <img>. Without them the browser doesn't know the aspect ratio and reflows the page on load (CLS).

passHomepage content is server-renderedCrawlability (Google)

Homepage server response contains 830 words of visible text — content is reachable without executing JavaScript.

passDOM size is reasonableStructured data & HTML

Homepage contains ~1100 elements.

passHeading hierarchy is intactStructured data & HTML

21 headings, no level skips.

pass<html lang> attributeStructured data & HTML

Language declared as "nl-NL".

passImages have alt textStructured data & HTML

25 of 25 <img> tags have alt attributes.

passInternal links on homepageStructured data & HTML

98 internal links found.

passSemantic landmark elementsStructured data & HTML

All four landmark elements present (main, header, footer, nav).

passKey pages have <title> and <h1>Key pages crawl

All 12 reachable key pages have both a <title> and <h1>.

passKey pages are server-renderedKey pages crawl

All 12 pages return ≥80 words of visible text without JavaScript.

Operability

Can agents actually operate the page?

failAccessibility tree is agent-navigableAccessibility

3 of 13 agent-critical accessibility audits failed (`button`, `link`, and `menuitem` elements do not have accessible names., `[aria-*]` attributes do not match their roles, Elements with an ARIA `[role]` that require children to contain a specific `[role]` are missing some or all of those required children.) — an agent may be unable to identify or operate the affected elements.

Fix: Fix the failing agent-accessibility audits listed below (accessible names on controls, valid ARIA roles/relationships, nothing interactive hidden from the tree).

fail`[aria-*]` attributes do not match their rolesAccessibility

Lighthouse flagged this audit — agents may be unable to perceive or operate the affected elements.

Fix: Remove ARIA attributes that aren't allowed on the element's role.

fail`button`, `link`, and `menuitem` elements do not have accessible names.Accessibility

Lighthouse flagged this audit — agents may be unable to perceive or operate the affected elements.

Fix: Give ARIA buttons/links/menuitems an accessible name.

failElements with an ARIA `[role]` that require children to contain a specific `[role]` are missing some or all of those required children.Accessibility

Lighthouse flagged this audit — agents may be unable to perceive or operate the affected elements.

Fix: Ensure ARIA roles that need specific children contain them (e.g. list → listitem).

failForm fields have labelsStructured data & HTML

Only 0 of 1 visible interactive form fields have labels.

Fix: Associate every input with a label. Form-filling agents (and screen readers) need it to know what to type into each field.

failWebMCP tools registered with the browserWebMCP tools

The page registers no tools via the navigator.modelContext browser API, so an AI agent has no structured way to operate it.

Fix: Expose your site’s actions to AI agents with the WebMCP browser API: call navigator.modelContext.registerTool({ name, description, inputSchema, execute }) from your page so an agent can invoke them. Implement it directly, or with a library like the @mcp-b polyfill (https://mcp-b.ai). Spec: https://github.com/webmachinelearning/webmcp.

warnOverall accessibility scoreAccessibility

Lighthouse accessibility score: 81/100. Agents read the page through its accessibility tree, so this is a proxy for how navigable your site is to an AI agent.

Fix: Resolve the failing accessibility audits below — each one removes an element or relationship an agent would otherwise be blind to.

pass`[aria-hidden="true"]` is not present on the document `<body>`Accessibility

`[aria-hidden="true"]` is not present on the document `<body>` passed.

pass`[aria-hidden="true"]` elements do not contain focusable descendentsAccessibility

`[aria-hidden="true"]` elements do not contain focusable descendents passed.

pass`[role]`s have all required `[aria-*]` attributesAccessibility

`[role]`s have all required `[aria-*]` attributes passed.

`[role]`s are contained by their required parent element passed.

`[role]` values are valid passed.

pass`[aria-*]` attributes are valid and not misspelledAccessibility

`[aria-*]` attributes are valid and not misspelled passed.

pass`[aria-*]` attributes have valid valuesAccessibility

`[aria-*]` attributes have valid values passed.

passButtons have an accessible nameAccessibility

infoTool catalog signpost publishedWebMCP tools

No tool catalog was found at /.well-known/webmcp.json (or /.well-known/webmcp). The catalog is a community convention, not part of the WebMCP standard, so this does not affect WebMCP presence.

Fix: Consider also publishing a tool catalog at /.well-known/webmcp.json: a JSON document with a "spec" of "webmcp/0.1" and a "tools" array, where each tool declares a name and a clear description. It is a community convention (optional, not part of the WebMCP standard) that lets crawlers and agents discover your tools without executing JavaScript.

Trust & Security

Can agents safely transact?

warnOAuth authorization server metadataOpen agent protocols

/.well-known/oauth-authorization-server returned the site's HTML app shell — treating as not published.

Fix: Publish /.well-known/oauth-authorization-server so AI agents discovering your OAuth setup can negotiate flows automatically. Required if your site offers an authenticated API.

warnOAuth protected-resource metadataOpen agent protocols

/.well-known/oauth-protected-resource returned the site's HTML app shell — treating as not published.

Fix: Publish /.well-known/oauth-protected-resource so AI agents discovering your OAuth setup can negotiate flows automatically. Required if your site offers an authenticated API.

warnWeb Bot Auth signature headerOpen agent protocols

No Web Bot Auth signature headers — sites can't verify agent identity.

Fix: Web Bot Auth (IETF HTTP Message Signatures over Signature / Signature-Input) lets you cryptographically verify which agent is hitting you. Several CDNs offer turn-key support; otherwise skip until vendor support matures.

warnContent-Security-Policy headerSecurity & trust

No Content-Security-Policy header on the homepage.

Fix: Add a Content-Security-Policy. Even a strict default-src directive cuts XSS blast radius dramatically. Start in report-only mode to find violations.
