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.

What this means for vans.com

On vans.com (Custom), 1 of 5 readable agent standards are in place: Wikidata. Missing: A2a, Anp, Ucp, Ap2.

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

vans.com scores higher than 29% of the 116 sites checked here so far; the average readiness score is 25/100.

Make vans.com agent-ready

Start with the highest-impact gap: A2a. 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 vans.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.
