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.

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 1 heading level skip (e.g. h2 → h4).

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 alt textStructured data & HTML

32 of 35 images have alt attributes (91%).

Fix: Add alt text to the remaining images. Empty alt="" is fine for purely-decorative graphics.

warnImages have explicit dimensionsStructured data & HTML

Only 0/35 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.

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

12 of 12 pages are missing <title> and/or <h1>: /sitemap_dede.xml.gz, /sitemap_enau.xml.gz, /sitemap_enca.xml.gz, /sitemap_enfr.xml.gz, /sitemap_engb.xml.gz, /sitemap_enin.xml.gz, /sitemap_enno.xml.gz, /sitemap_ennz.xml.gz, /sitemap_enus.xml.gz, /sitemap_esar.xml.gz, /sitemap_eses.xml.gz, /sitemap_frca.xml.gz.

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.

passHomepage content is server-renderedCrawlability (Google)

Homepage server response contains 1673 words of visible text — content is reachable without executing JavaScript.

passData tables use <thead>Structured data & HTML

1 table(s), all with <thead>.

passDOM size is reasonableStructured data & HTML

Homepage contains ~1378 elements.

pass<html lang> attributeStructured data & HTML

Language declared as "en-GB".

passInternal links on homepageStructured data & HTML

18 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 are server-renderedKey pages crawl

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

Operability

Can agents actually operate the page?

fail`[role]` values are not validAccessibility

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

Fix: Use only valid ARIA role values.

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.

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

2 of 11 agent-critical accessibility audits failed (Links do not have a discernible name, `[role]` values are not valid) — 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: 87/100. 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.

warnForms use autocomplete attributesStructured data & HTML

No autocomplete attributes on any data-collecting form field.

Fix: Add autocomplete hints (email, tel, name, etc.) so form-filling agents and browsers can populate fields without guessing.

warnForm errors are accessibleStructured data & HTML

0/2 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.

warnForm fields have labelsStructured data & HTML

3 of 4 visible interactive form fields have labels.

Fix: Associate every input with a label — either wrap it in <label>, link via for/id, or set aria-label / aria-labelledby.

warnForms mark required fieldsStructured data & HTML

0/2 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

844ms (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.

infoWebMCP form coverageLighthouse Agentic

2 forms 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?

failNo mixed-content referencesSecurity & trust

Found 4 http:// references 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.
