Can agents find your site and its capabilities?
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.
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.
Found https://hyundai.com/llms.txt.
Found at least one "[name](url)" markdown link.
Found a "> summary" blockquote.
First line is a top-level "# Title" heading.
Crawled 12 of 12 discovered pages beyond the homepage.
Could not identify a known website platform (custom stack or unrecognised).
Can agents understand your content?
No <h1> tag found on the homepage.
Fix: Add exactly one <h1> that names the page. AI summarisers use it as the document title.
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.
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).
Homepage server response contains 830 words of visible text — content is reachable without executing JavaScript.
Homepage contains ~1100 elements.
21 headings, no level skips.
Language declared as "nl-NL".
25 of 25 <img> tags have alt attributes.
98 internal links found.
All four landmark elements present (main, header, footer, nav).
All 12 reachable key pages have both a <title> and <h1>.
All 12 pages return ≥80 words of visible text without JavaScript.
Can agents actually operate the page?
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).
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.
Lighthouse flagged this audit — agents may be unable to perceive or operate the affected elements.
Fix: Give ARIA buttons/links/menuitems an accessible name.
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).
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.
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.
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.
`[aria-hidden="true"]` is not present on the document `<body>` passed.
`[aria-hidden="true"]` elements do not contain focusable descendents passed.
`[role]`s have all required `[aria-*]` attributes passed.
`[role]`s are contained by their required parent element passed.
`[role]` values are valid passed.
`[aria-*]` attributes are valid and not misspelled passed.
`[aria-*]` attributes have valid values passed.
Buttons have an accessible name passed.
Document has a `<title>` element passed.
Links have a discernible name passed.
0.040 (field data from CrUX) — good.
310ms (field data from CrUX) — good.
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.
Can agents safely transact?
/.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.
/.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.
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.
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.
