Crawler access (robots.txt)

0/2

0 of 8 AI crawlers may read the site, 8 disallowed

  • GET /robots.txt -> HTTP 200, 653 B, 3 user-agent groups
  • Disallowed: GPTBot (via *), ClaudeBot (via *), OAI-SearchBot (via *), PerplexityBot (via *), Google-Extended (via *), Amazonbot (via *), CCBot (via *), Bytespider (via *)
  • "User-agent: *" disallows the whole site; only crawlers named explicitly may read it
  • Content-Signal: ai-input=no, ai-train=no, search=yes
  • Sitemap declared: https://lobste.rs/sitemap.xml.gz

Fix: Add a group for GPTBot, ClaudeBot, OAI-SearchBot and the others with "Allow: /" (or drop the blanket "Disallow: /") if you want answer engines to cite you.

Machine-readable surfaces

1/2

None of the 7 machine-readable surfaces is published (a sitemap is declared in robots.txt)

  • /llms.txt: HTTP 404
  • /sitemap.xml: HTTP 404
  • /.well-known/x402: HTTP 404
  • /.well-known/agent-card.json: HTTP 404
  • /.well-known/mcp-registry-auth: HTTP 404
  • /openapi.json: HTTP 404
  • /ai.txt: HTTP 404
  • Sitemap declared in robots.txt instead: https://lobste.rs/sitemap.xml.gz

Fix: Publish /llms.txt (a short Markdown guide to your key pages); one agent surface: /openapi.json, /.well-known/agent-card.json, or /.well-known/x402 if you sell to agents.

Readable without JavaScript

2/2

Home page is readable

  • GET https://lobste.rs/ -> HTTP 200, text/html, 56 KB
  • 3,786 characters of visible text with scripts, styles and tags removed; <title>: "Lobsters"
  • 1 external script, 1 inline; <noscript> absent
  • first words: "Lobsters Active Recent Comments Search Login 73 Bill Gates tries to install Movie Maker windows techemails.com via nrposner 2026-09-28 11:18..."

Fix: Nothing to fix here.

Structured data

1/2

No JSON-LD, Open Graph complete

  • 0 JSON-LD blocks
  • Open Graph: og:title "Lobsters"; og:description present
  • meta description: absent

Fix: add a JSON-LD block (Organization or WebSite, plus Product, FAQPage or Article where relevant) so answer engines describe you accurately.

MCP census entry (index.agentexchange.work)

0/2

Not selling to agents: no census entry, no /mcp endpoint

  • Not in the census of 2,031 hosts selling to agents (2026-09-29)
  • GET /mcp -> HTTP 404: no MCP endpoint at the root

Fix: Expose a Streamable HTTP MCP endpoint at /mcp (or a paid x402 route) so agents can call you, not just read you.
