Agent Readiness

Discoverability

80/100

Can AI crawlers find your content and understand your policies?

  • ✓
    robots.txt present
    HTTP 200
  • ✓
    sitemap.xml present
    HTTP 200
  • !
    Sitemap declared in robots.txt
    Add a `Sitemap:` line to robots.txt
    How to fix

    Append a line like `Sitemap: https://yoursite.com/sitemap.xml` to robots.txt so crawlers find the sitemap immediately.

  • ✓
    AI bot rules in robots.txt
    Mentions GPTBot, ClaudeBot, Google-Extended, PerplexityBot
  • !
    Content Signals declared
    No Cloudflare Content-Signal directive
    How to fix

    Add `Content-Signal: search=yes, ai-train=no, ai-input=yes` (tune the values to your policy) inside a User-agent group in robots.txt.

Agent Endpoints

25/100

Standard well-known endpoints agents probe to interact with your site.

  • ✗
    MCP server card (/.well-known/mcp/server-card.json)
    Publish an MCP server card to expose agent tools
    How to fix

    Publish an MCP server-card JSON at /.well-known/mcp/server-card.json describing your tools, transport, and capabilities. Spec: SEP-1649/SEP-2127.

  • ✗
    API catalog (/.well-known/api-catalog)
    RFC 9727 API catalog helps agents discover your APIs
    How to fix

    Serve a `application/linkset+json` document at /.well-known/api-catalog listing your OpenAPI / service descriptions. RFC 9727.

  • ✗
    OAuth protected resource (/.well-known/oauth-protected-resource)
    RFC 9728 lets agents discover auth requirements
    How to fix

    Publish a JSON document at /.well-known/oauth-protected-resource with `resource` and `authorization_servers` fields. RFC 9728.

  • ✓
    OpenID configuration (/.well-known/openid-configuration)
    HTTP 200

Content Negotiation

67/100

How well your site speaks formats AI agents prefer.

  • ✓
    llms.txt present
    HTTP 200
  • !
    Markdown content negotiation
    Returned text/html; charset="utf-8" despite Accept: text/markdown
    How to fix

    When `Accept: text/markdown` is sent, return the same content as Markdown (Content-Type: text/markdown). Agents prefer it because it's cheaper to parse than HTML.

  • !
    Link header on /
    No Link header — agents can't follow alt-format relations
    How to fix

    Add an HTTP `Link:` header pointing agents at alternate representations, e.g. `Link: </openapi.json>; rel="service-desc"; type="application/openapi+json"`.

Search Optimization

56/100

HTML signals that Google AI Search + LLM crawlers use to rank you.

    Missing og:title / og:description / og:image
    How to fix

    Add JSON-LD (Organization, Product, FAQPage…)
