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.

warnKey pages discoveredKey pages crawl

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.

infoLighthouse Agentic Browsing runLighthouse Agentic

Lighthouse Agentic Browsing audits ran.

infoWebsite platformplatform

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

Understanding

Can agents understand your content?

failImages have alt textStructured data & HTML

Only 0 of 42 images have alt attributes (0%).

Fix: Add alt text to every <img>. Screen readers and AI vision models both rely on it to caption images.

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.

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

Only 0/42 images have width+height — large CLS risk.

Fix: Set width and height on every <img> so the browser reserves space before the image loads. A layout that shifts while loading makes an AI agent mis-click the element it targeted.

warnInternal links on homepageStructured data & HTML

Only 0 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.

passHomepage content is server-renderedCrawlability (Google)

Homepage server response contains 114 words of visible text — content is reachable without executing JavaScript.

passCookie banner does not block crawlersStructured data & HTML

Detected 1 cookie-banner element but none look agent-hostile (small, dismissible, or offer a reject option).

passDOM size is reasonableStructured data & HTML

Homepage contains ~158 elements.

passHeading hierarchy is intactStructured data & HTML

24 headings, no level skips.

pass<html lang> attributeStructured data & HTML

Language declared as "en".

passSingle H1 on homepageStructured data & HTML

Exactly one <h1> on the homepage.

Operability

Can agents actually operate the page?

failAccessibility tree is not well-formedLighthouse Agentic

A well-formed [accessibility tree](http://goo.gle/lighthouse-agentic-a11y) helps AI agents to navigate and interact with 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.

warnOverall accessibility scoreAccessibility

Lighthouse accessibility score: 89/100. 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.

passAccessibility tree is agent-navigableAccessibility

All 10 agent-critical accessibility audits passed — an agent can perceive and operate the page through its accessibility tree.

infoWebMCP tools registeredLighthouse Agentic

Lists the [WebMCP tools](http://goo.gle/webmcp-docs) registered at the time of analysis.

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?

failNo mixed-content referencesSecurity & trust

Found 1 http:// reference in the homepage HTML — browsers will block these resources.

Fix: Update every http:// resource URL to https:// (or use protocol-relative `//`). Common offenders: image CDNs and legacy embed snippets.

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=7884000 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.

warnNo tech-stack disclosure in headersSecurity & trust

server: Apache/2.4.68 ()

Fix: Configure your web server / framework to suppress version strings. They give attackers a free shortlist of known CVEs to try.

warnMIME-sniff protectionSecurity & trust

No `X-Content-Type-Options: nosniff` header.

Fix: Add `X-Content-Type-Options: nosniff` to prevent browsers (and some agents) from re-interpreting your responses as a different content type.

passCDN detectedSecurity & trust

x-akamai-transformed: 0 - 0 - (Akamai)

passContent-Security-Policy headerSecurity & trust
