What does the agent readiness check test?

Real protocol probes of .well-known files (openapi.json, mcp.json, ai-plugin.json, security.txt), a live MCP initialize handshake, A2A agent-card validation, a 20-user-agent crawler audit, and a JS-parity check.

Partly ready

lenscrafters.com has 2 of 3 readable agent standards in place; missing Webmcp. 6 could not be read because the site refused our request (Mcp, A2a, Anp, Ucp, Ap2, Openapi), so they are not counted.

Assessment

2 of 3 readable agent-readiness checks verified (6 could not be read: the site refused our request). 15 AI crawler user-agent(s) got an error at the edge although robots.txt allows them. See per-protocol drawers for evidence and fix-it files.

AI crawler audit

3 of 18 AI user-agents reached the homepage; 15 returned an error to a request carrying their user-agent string although robots.txt allows it.

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 lenscrafters.com

On lenscrafters.com (Custom), 2 of 3 readable agent standards are in place: Llms Txt, Wikidata. Missing: Webmcp.

Without JavaScript, your brand name still appears in the raw HTML, so crawlers that do not run JS can read it.

lenscrafters.com scores higher than 99% of the 127 sites checked here so far; the average readiness score is 24/100.

Make lenscrafters.com agent-ready

Start with the highest-impact gap: Webmcp. 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 lenscrafters.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.
