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.
Found https://webex.com/llms.txt.
Found at least one "[name](url)" markdown link.
Found a "> summary" blockquote.
First line is a top-level "# Title" heading.
Crawled 3 of 12 discovered pages beyond the homepage.
Lighthouse Agentic Browsing audits ran.
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.
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.
75 of 78 images have alt attributes (96%).
Fix: Add alt text to the remaining images. Empty alt="" is fine for purely-decorative graphics.
Only 1/78 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.
Found 2 <h1> tags. Most AI summarisers expect exactly one.
Fix: Demote the secondary H1s to H2 — keep H1 reserved for the page title.
1 of 3 pages are missing <title> and/or <h1>: /products.
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.
Homepage server response contains 1410 words of visible text — content is reachable without executing JavaScript.

Can agents actually operate the page?
3 of 14 agent-critical accessibility audits failed (`[role]`s do not have all required `[aria-*]` attributes, `[aria-*]` attributes do not match their roles, 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: Remove ARIA attributes that aren't allowed on the element's role.
Lighthouse flagged this audit — agents may be unable to perceive or operate the affected elements.
Fix: Add the ARIA attributes each role requires.
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).
A well-formed [accessibility tree](http://goo.gle/lighthouse-agentic-a11y) helps AI agents to navigate and interact with the page.

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.
Lighthouse accessibility score: 78/100. 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.
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]` 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.
ARIA IDs are unique passed.
Links have a discernible name passed.
0.060 (field data from CrUX) — good.

Lists the [WebMCP tools](http://goo.gle/webmcp-docs) registered at the time of analysis.
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?
Found 1 http:// reference 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.
/.well-known/oauth-authorization-server returned 500.
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 500.
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.
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.
