Can agents find your site and its capabilities?
Discovered 12 candidate pages but none were reachable.
Fix: Make sure the pages linked from your sitemap and navigation return HTTP 200 to non-browser clients — agents fetch them the same way our crawler does.
Could not identify a known website platform (custom stack or unrecognised).
Can agents understand your content?
No links found on the homepage.
Fix: Add navigation links so AI crawlers can find the rest of your content. A bare landing page is invisible to anything that doesn't already know where to look.
No semantic landmark elements (main, header, footer, nav) detected on the homepage.
Fix: Wrap your page structure in semantic landmarks. AI structural extractors rely on them to separate navigation from content from boilerplate.
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.
Homepage server response contains only 11 words of visible text. AI agents that don't execute JavaScript may see an empty page.
Fix: Consider pre-rendering or server-rendering the homepage so AI crawlers (which typically don't run JS) can see the content. Frameworks: Next.js (Server Components), Nuxt SSR, Astro, or Vite SSG.
Homepage contains ~113 elements.
1 headings, no level skips.
Language declared as "en".
Can agents actually operate the page?
All 13 agent-critical accessibility audits passed — an agent can perceive and operate the page through its accessibility tree.
`[aria-*]` attributes match their roles passed.
Uses ARIA roles only on compatible elements passed.
`button`, `link`, and `menuitem` elements have accessible names passed.
`[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.
Lighthouse accessibility score: 97/100. Agents read the page through its accessibility tree, so this is a proxy for how navigable your site is to an AI agent.
0.090 (field data from CrUX) — good.
358ms (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 404.
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 404.
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.
