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.

pass/llms.txt guide for AI agentsAgent manifests

Found https://calendly.com/llms.txt.

pass/llms.txt lists key pages as markdown linksAgent manifests

Found at least one "[name](url)" markdown link.

pass/llms.txt has a summary blockquoteAgent manifests

Found a "> summary" blockquote.

pass/llms.txt opens with an H1 titleAgent manifests

First line is a top-level "# Title" heading.

passKey pages discoveredKey pages crawl

Crawled 12 of 12 discovered pages beyond the homepage.

passllms.txt follows recommendationsLighthouse Agentic

If your llms.txt file does not follow recommendations, large language models may not be able to understand how you want your website to be crawled or used for training. The [llms.txt](https://llmstxt.org/) file should be a Markdown file containing at least one H1 header.

Understanding

Can agents understand your content?

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.

warnDOM size is reasonableStructured data & HTML

Homepage contains ~3328 elements — well above the 1500-element budget.

Fix: Trim the homepage DOM: an AI agent has to read all of it before acting, and this page is several times over budget. Long product carousels, hidden modal markup and large tracker scripts are common culprits.

warnHeading hierarchy is intactStructured data & HTML

Detected 5 heading level skips (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 explicit dimensionsStructured data & HTML

Only 0/37 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: main.

passHomepage content is server-renderedCrawlability (Google)

Homepage server response contains 993 words of visible text — content is reachable without executing JavaScript.

pass<html lang> attributeStructured data & HTML

Language declared as "en".

passImages have alt textStructured data & HTML

37 of 37 <img> tags have alt attributes.

passInternal links on homepageStructured data & HTML

138 internal links found.

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?

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: 88/100. 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?

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.

warnClick-jacking protectionSecurity & trust

No X-Frame-Options header and no CSP frame-ancestors directive.

Fix: Add `X-Frame-Options: SAMEORIGIN` (or a CSP frame-ancestors directive) to prevent your site being framed by a phishing host.

passOAuth authorization server metadataOpen agent protocols

/.well-known/oauth-authorization-server returns parseable JSON.
