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/.well-known/api-catalog (RFC 9727)Agent manifests

Found a parseable Linkset at https://planetscale.com/.well-known/api-catalog.

pass/llms.txt guide for AI agentsAgent manifests

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

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

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

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

Understanding

Can agents understand your content?

passMarkdown content negotiationOpen agent protocols

Homepage returns text/markdown when requested.

passHomepage content is server-renderedCrawlability (Google)

Homepage server response contains 1880 words of visible text — content is reachable without executing JavaScript.

passDOM size is reasonableStructured data & HTML

Homepage contains ~631 elements.

passHeading hierarchy is intactStructured data & HTML

14 headings, no level skips.

pass<html lang> attributeStructured data & HTML

Language declared as "en".

Exactly one <h1> on the homepage.

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.

passAccessibility tree is agent-navigableAccessibility

All 11 agent-critical accessibility audits passed — an agent can perceive and operate the page through its accessibility tree.

passOverall accessibility scoreAccessibility

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.

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 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.

warnHTTP Strict-Transport-Security headerSecurity & trust

HSTS configured (max-age=63072000) but missing includeSubDomains.

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

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.

warnMIME-sniff protectionSecurity & trust

No `X-Content-Type-Options: nosniff` header.

Fix: Add `X-Content-Type-Options: nosniff` to prevent browsers (and some agents) from re-interpreting your responses as a different content type.

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.

passCDN detectedSecurity & trust

cf-ray: a1eb69ab7b6d1983-FRA (Cloudflare); x-vercel-id: fra1::lwqfm-1784649565989-28065378a2dc (Vercel)

passContent-Security-Policy headerSecurity & trust

passTLS certificate is not near expirySecurity & trust

Valid for 64 more days (Sep 23 17:50:22 2026 GMT, issuer: YR1).

passNo tech-stack disclosure in headersSecurity & trust

Server / X-Powered-By headers don't leak product version.
