  2. MCP census entry (+2 points): Expose a Streamable HTTP MCP endpoint at /mcp (or a paid x402 route) so agents can call you, not just read you. How to fix

relay.preflightstack.com is graded D. The $49 AI Visibility Full Report shows what AI assistants say about relay.preflightstack.com's brand, with fixes for crawler access, llms.txt and schema, and tests 8 real buyer questions across ChatGPT-class models to show what AI answers say about you today.

Crawler access (robots.txt)

2/2 · pass

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

  • GET /robots.txt -> HTTP 200, 1.2 KB, 0 user-agent groups
  • Unmentioned (allowed by default): GPTBot, ClaudeBot, OAI-SearchBot, PerplexityBot, Google-Extended, Amazonbot, CCBot, Bytespider

Fix: Name the AI crawlers you allow explicitly so your policy survives a future change to the "User-agent: *" group.

Machine-readable surfaces

2/2 · pass

2 of 7 surfaces present (/llms.txt, /openapi.json)

  • /llms.txt: HTTP 200, 3.2 KB of text
  • /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 200, valid JSON (OpenAPI 3.1.0)
  • /ai.txt: HTTP 404

Fix: Publish /sitemap.xml.

Readable without JavaScript

0/2 · fail

Home page is not available to a plain fetch (HTTP 404)

  • GET https://relay.preflightstack.com/ -> HTTP 404, application/json, 122 B

Fix: Your edge serves a challenge or error to non-browser fetchers; allowlist the AI crawlers you want (at least for the home page) or serve them a static version.

Structured data

not measured

Home page returned HTTP 404; structured data not measurable

  • GET https://relay.preflightstack.com/ -> HTTP 404, application/json

Fix: Let non-browser fetchers reach the home page first.

MCP census entry (index.agentexchange.work)

0/2 · fail

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

  • census unavailable (refused index.agentexchange.work: hosts on agentexchange.work cannot be graded from inside the same Cloudflare zone; every check would time )
  • 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.
