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.

infoWebsite platformplatform

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

Understanding

Can agents understand your content?

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.

warnHeading hierarchy is intactStructured data & HTML

Detected 11 heading level skips (e.g. h2 → h6).

Fix: Tighten the heading order so each level only steps down by one. Skipped levels confuse both screen-readers and AI structural extractors.

warnImages have explicit dimensionsStructured data & HTML

Only 49/66 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.

warnSemantic landmark elementsStructured data & HTML

Missing landmark elements: header.

warnSingle H1 on homepageStructured data & HTML

Found 2 <h1> tags. Most AI summarisers expect exactly one.

Fix: Demote the secondary H1s to H2 — keep H1 reserved for the page title.

passHomepage content is server-renderedCrawlability (Google)

Homepage server response contains 4789 words of visible text — content is reachable without executing JavaScript.

passDOM size is reasonableStructured data & HTML

Homepage contains ~1177 elements.

pass<html lang> attributeStructured data & HTML

Language declared as "en-US".

passImages have alt textStructured data & HTML

66 of 66 <img> tags have alt attributes.

passInternal links on homepageStructured data & HTML

60 internal links found.

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.

passAccessibility tree is agent-navigableAccessibility

All 10 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`[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.

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.

passButtons have an accessible nameAccessibility

Buttons have an accessible name 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.

passForm fields have labelsStructured data & HTML

2 of 2 visible interactive form fields have labels.

passCumulative Layout ShiftPerformance

0.000 (field data from CrUX) — good.

passTime to First BytePerformance

130ms (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.

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

x-powered-by: engage-v1

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