Can agents find your site and its capabilities?
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 11 of 12 discovered pages beyond the homepage.
Could not identify a known website platform (custom stack or unrecognised).
Can agents understand your content?
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.
No <h1> tag found on the homepage.
Fix: Add exactly one <h1> that names the page. AI summarisers use it as the document title.
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.
Only 0/4 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.
Only 3 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.
Homepage server response contains 234 words of visible text — content is reachable without executing JavaScript.
Homepage contains ~241 elements.
1 headings, no level skips.
Language declared as "en".
4 of 4 <img> tags have alt attributes.
All 11 reachable key pages have both a <title> and <h1>.
All 11 pages return ≥80 words of visible text without JavaScript.
Can agents actually operate the page?
3 of 14 agent-critical accessibility audits failed (Links do not have a discernible name, ARIA input fields do not have accessible names, Elements with an ARIA `[role]` that require children to contain a specific `[role]` are missing some or all of those required children.) — 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).
Lighthouse flagged this audit — agents may be unable to perceive or operate the affected elements.
Fix: Give ARIA input fields an accessible name.
Lighthouse flagged this audit — agents may be unable to perceive or operate the affected elements.
Fix: Ensure ARIA roles that need specific children contain them (e.g. list → listitem).
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.
0.260 (field data from CrUX) — poor.
Fix: A layout that shifts while loading makes an AI agent mis-click the element it targeted. Eliminate CLS by setting explicit width/height on images and embeds, avoiding inserted content above existing content, and reserving space for ad slots.
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.
`[aria-*]` attributes match their roles passed.
Uses ARIA roles only on compatible elements passed.
`button`, `link`, and `menuitem` elements have accessible names passed.
`[aria-hidden="true"]` is not present on the document `<body>` passed.
`[aria-hidden="true"]` elements do not contain focusable descendents passed.
`[role]`s have all required `[aria-*]` attributes passed.
`[role]` values are valid passed.
`[aria-*]` attributes are valid and not misspelled passed.
`[aria-*]` attributes have valid values passed.
Buttons have an accessible name passed.
Document has a `<title>` element passed.
Lighthouse accessibility score: 90/100. Agents read the page through its accessibility tree, so this is a proxy for how navigable your site is to an AI agent.
314ms (field data from CrUX) — good.
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.
Can agents safely transact?
/.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.
/.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.
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.
HSTS max-age=2628000 is below six months.
Fix: Raise max-age to at least 15768000 (six months). The HSTS preload list requires 31536000 (one year).
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.
server: nginx/1.29.7
Fix: Configure your web server / framework to suppress version strings. They give attackers a free shortlist of known CVEs to try.
