costadelmar.com has 1 of 9 readable agent standards in place; missing Mcp, Webmcp, A2a, Anp, Ucp, Ap2, Openapi, Wikidata.

Assessment

1 of 9 readable agent-readiness checks verified. Our request with an ordinary browser user-agent was refused too, so the crawler results describe our checker being blocked, not rules about AI crawlers. See per-protocol drawers for evidence and fix-it files.

AI crawler audit

1 of 18 AI user-agents reached the homepage.

Our request with an ordinary browser user-agent was refused as well (HTTP 200 before, 0 after). This site was blocking our checker, so read these counts as "could not check", not as rules about AI crawlers.

9 of 18 were tested with the operator's published user-agent string and the rest with the bare token, since no published string was found. A request that only names a user-agent does not prove the real crawler would be treated the same.

What this means for costadelmar.com

On costadelmar.com (Custom), 1 of 9 readable agent standards are in place: Llms Txt. Missing: Mcp, Webmcp, A2a, Anp, Ucp, Ap2, Openapi, Wikidata.

Without JavaScript, your brand name does not appear in the raw HTML, so crawlers that do not run JS see an empty shell.

costadelmar.com scores higher than 17% of the 127 sites checked here so far; the average readiness score is 24/100.

Make costadelmar.com agent-ready

Start with the highest-impact gap: Mcp. Publish a working MCP endpoint at /.well-known/mcp.json (the initialize handshake must succeed, not just return 200), add an A2A agent card, and keep the crawler path clean.

Frequently asked questions

Are these real probes or AI guesses?

Real probes. We fetch the actual files, run a real MCP initialize handshake, and validate A2A cards against their schema. No model decides a verdict.

Does costadelmar.com need every standard to pass?

No. Start with the highest-impact gap above, then add the rest. Most sites win the most by shipping a working MCP endpoint and keeping the crawler path clean.
