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.

Crawled 12 of 12 discovered pages beyond the homepage.

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.

warnDOM size is reasonableStructured data & HTML

Homepage contains ~1766 elements — heavy.

Fix: Aim for under 1500 elements on the homepage. Heavier DOMs slow first paint and overflow some AI crawlers' parse buffers.

warnImages have explicit dimensionsStructured data & HTML

109/113 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).

passHomepage content is server-renderedCrawlability (Google)

Homepage server response contains 1915 words of visible text — content is reachable without executing JavaScript.

passHeading hierarchy is intactStructured data & HTML

43 headings, no level skips.

pass<html lang> attributeStructured data & HTML

Language declared as "en".

passImages have alt textStructured data & HTML

113 of 113 <img> tags have alt attributes.

passInternal links on homepageStructured data & HTML

32 internal links found.

passSemantic landmark elementsStructured data & HTML

All four landmark elements present (main, header, footer, nav).

passSingle H1 on homepageStructured data & HTML

Exactly one <h1> on the homepage.

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

All 12 reachable key pages have both a <title> and <h1>.

passKey pages are server-renderedKey pages crawl

All 12 pages return ≥80 words of visible text without JavaScript.

Operability

Can agents actually operate the page?

failLinks do not have a discernible nameAccessibility

Lighthouse flagged this audit — agents may be unable to perceive or operate the affected elements.

Fix: Give every link discernible text (avoid bare icons / "click here") so agents know where it goes.

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.

failTime to First BytePerformance

2.12s (field data from CrUX) — poor.

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.

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.

warnAccessibility tree is agent-navigableAccessibility

1 of 10 agent-critical accessibility audits failed (Links do not have a discernible name) — 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).

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.

warnForm errors are accessibleStructured data & HTML

0/1 data-collecting forms expose errors via ARIA attributes.

Fix: Wire inputs to their error containers with `aria-describedby` and toggle `aria-invalid` on validation failure. Agents that can't see styled error text rely on these attributes.

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.

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.

passForms use autocomplete attributesStructured data & HTML

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

passForm fields have labelsStructured data & HTML

2 of 2 visible interactive form fields have labels.

0.000 (field data from CrUX) — good.

infoWebMCP form coverageLighthouse Agentic

1 form missing annotations

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?

failHTTP Strict-Transport-Security headerSecurity & trust

No Strict-Transport-Security header on the homepage.

Fix: Add `Strict-Transport-Security: max-age=15768000; includeSubDomains` so browsers and agents refuse to downgrade to http for at least six months.

warnOAuth authorization server metadataOpen agent protocols

/.well-known/oauth-authorization-server returned 403.

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 403.

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.

warnContent-Security-Policy headerSecurity & trust

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.

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.

passCDN detectedSecurity & trust
