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.

failllms.txt does not follow 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.

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

Per llmstxt.org, group key pages under "## Section" headings as "[name](url)" links.

Fix: Add "## Docs" / "## Products" sections listing your key pages as markdown links.

warn/llms.txt has a summary blockquoteAgent manifests

Per llmstxt.org, follow the H1 with a "> short summary" blockquote.

Fix: Add a "> One-sentence description of your site." blockquote under the H1.

warn/llms.txt opens with an H1 titleAgent manifests

Per llmstxt.org, /llms.txt should open with a single "# Project name" H1.

Fix: Make the first line of /llms.txt a "# Your site name" H1.

warnKey pages discoveredKey pages crawl

Discovered 12 candidate pages but none were reachable.

Fix: Make sure the pages linked from your sitemap and navigation return HTTP 200 to non-browser clients — agents fetch them the same way our crawler does.

Understanding

Can agents understand your content?

failHTML readiness checks ranStructured data & HTML

Homepage returned 403 — couldn't analyse structure.

warnMarkdown content negotiationOpen agent protocols

Homepage returned 403 for Accept: text/markdown.

warnHomepage content is server-renderedCrawlability (Google)

Homepage returned 403.

Operability

Can agents actually operate the page?

failCumulative Layout ShiftPerformance

0.280 (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.

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.

warnTime to First BytePerformance

1.07s (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.

passAccessibility tree is agent-navigableAccessibility

All 14 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 authorization server metadataOpen agent protocols

/.well-known/oauth-authorization-server returned the site's HTML app shell — treating as not published.

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 the site's HTML app shell — treating as not published.

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

Homepage returned 403.

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.

warnHTTP Strict-Transport-Security headerSecurity & trust

HSTS configured (max-age=15768000) but missing includeSubDomains.

Fix: Add `includeSubDomains` so subdomains inherit the policy.

Homepage returned 403 — couldn't scan for error markers.

Homepage returned 403 — couldn't scan for mixed content.
