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
  • !
    AI bot rules in robots.txt
    No explicit rules for GPTBot / ClaudeBot / Google-Extended
    How to fix

    Add `User-agent: GPTBot`, `User-agent: ClaudeBot`, `User-agent: Google-Extended` blocks with explicit Allow/Disallow so AI crawlers know your stance.

  • !
    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

85/100

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

  • Homepage reachable
    HTTP 200
  • HTTPS
  • Title tag
    Slack | AI Work Platform & Productivity ToolsClose NavigationClose Navigation
  • Meta description
    Boost productivity and save time with Slack‌ — ‌the AI work platform for managing projects…
  • Canonical URL
  • Open Graph tags
    title, description, image
  • Schema.org structured data
    Add JSON-LD (Organization, Product, FAQPage…)
    How to fix

    Embed a `<script type="application/ld+json">` block with an Organization, Product, FAQPage, or HowTo schema. Validate with schema.org/validator.

  • Mobile viewport
  • html lang attribute
  • !
    Image alt text
    54/79 images have alt
    How to fix

    Add descriptive `alt` text to every `<img>` (use `alt=""` for purely decorative images). Improves accessibility AND AI/SEO ranking.

Auth Standards optional

0/100

Optional: cryptographic verification for trusted bots.

  • Web Bot Auth directory
    Publish /.well-known/http-message-signatures-directory to verify trusted bots
    How to fix

    If you operate a bot, publish your signing keys at /.well-known/http-message-signatures-directory per draft-meunier-web-bot-auth-architecture. Most non-bot sites can leave this missing.
