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.

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?

failSemantic landmark elementsStructured data & HTML

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.

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.

warnHomepage content is server-renderedCrawlability (Google)

Homepage server response contains only 76 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.

warnInternal links on homepageStructured data & HTML

Only 2 internal links on the homepage.

Fix: Add at least 5-10 internal links pointing to your top product, pricing, docs, blog and about pages so an AI agent can navigate to them from the homepage.

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

12 of 12 pages are missing <title> and/or <h1>: /contact, /contact-us, /pricing, /plans, /about, /about-us, /services, /products, /blog, /news, /faq, /help.

Fix: Make sure every page sets a unique <title> and exactly one <h1>. The title is how an AI agent confirms it landed on the right page after navigating.

warnKey pages are server-renderedKey pages crawl

11 of 12 pages return <80 words of visible text — agents without JavaScript see an empty page: /contact (76w), /contact-us (2w), /pricing (76w), /plans (7w), /about-us (76w), /services (76w), /products (76w), /blog (76w), /news (76w), /faq (76w), /help (3w).

Fix: Pre-render or server-render these pages so AI crawlers (which usually don't execute JS) can read them. Frameworks: Next.js Server Components, Nuxt SSR, Astro, or build-time prerendering.

passDOM size is reasonableStructured data & HTML

Homepage contains ~352 elements.

pass<html lang> attributeStructured data & HTML

Language declared as "en".

Operability

Can agents actually operate the page?

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.

warnForms mark required fieldsStructured data & HTML

0/1 data-collecting forms mark required fields.

Fix: Add the `required` attribute (or `aria-required="true"`) to mandatory inputs. Form-filling agents skip optional fields by default — without markers they over-fill.

warnForm fields publish validation hintsStructured data & HTML

No HTML5 validation hints (pattern / minlength / maxlength / min / max) on any data-collecting form input.

Fix: Publish input constraints via HTML attributes so agents and browsers can validate client-side.

warnTime to First BytePerformance

834ms (field data from CrUX) — needs improvement.

Fix: Every request an AI agent makes pays this server latency, and agents make many requests per task. Reduce TTFB with edge caching, a CDN, and shipping less server-side work per request.

passAccessibility tree is agent-navigableAccessibility

All 9 agent-critical accessibility audits passed — an agent can perceive and operate the page through its accessibility tree.

pass`[aria-*]` attributes match their rolesAccessibility

`[aria-*]` attributes match their roles passed.

pass`button`, `link`, and `menuitem` elements have accessible namesAccessibility

`button`, `link`, and `menuitem` elements have accessible names passed.

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

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

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

pass`[role]` values are validAccessibility

`[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.

passDocument has a `<title>` elementAccessibility

Document has a `<title>` element passed.

passLinks have a discernible nameAccessibility

Links have a discernible name passed.

passOverall accessibility scoreAccessibility

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

passForms use autocomplete attributesStructured data & HTML

All 1 data-collecting forms set autocomplete on at least one field.

passForm errors are accessibleStructured data & HTML

All 1 data-collecting forms reference errors via aria-describedby / aria-invalid.

passForm fields have labelsStructured data & HTML

2 of 2 visible interactive form fields have labels.

passCumulative Layout ShiftPerformance

0.090 (field data from CrUX) — good.

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 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.

warnOAuth protected-resource metadataOpen agent protocols

/.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.

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.

warnHTTP Strict-Transport-Security headerSecurity & trust

HSTS max-age=15552000 is below six months.

Fix: Raise max-age to at least 15768000 (six months). The HSTS preload list requires 31536000 (one year).

warnReferrer-Policy headerSecurity & trust

No Referrer-Policy header on the homepage.

Fix: Add `Referrer-Policy: strict-origin-when-cross-origin` so outbound links don't leak full URLs (including query strings) to third parties.

warnTLS certificate is not near expirySecurity & trust

Certificate expires in 7 days (Jul 28 23:59:59 2026 GMT).

Fix: Renew within the week — automated renewal (Let's Encrypt + cron / certbot) avoids manual outages.

passContent-Security-Policy headerSecurity & trust

CSP header present.

passSite is served over HTTPSSecurity & trust

Homepage scheme is https:.

passhttp:// redirects to https://Security & trust

http://facebook.com → https://www.facebook.com/ (2 hops).

passHomepage shows no error outputSecurity & trust

No stack-trace markers in the first 5KB.

passNo mixed-content referencesSecurity & trust

Homepage HTML references no http:// resources.

passNo tech-stack disclosure in headersSecurity & trust

Server / X-Powered-By headers don't leak product version.

passMIME-sniff protectionSecurity & trust

X-Content-Type-Options: nosniff.

passClick-jacking protectionSecurity & trust

X-Frame-Options: DENY.
