@AnthropicAI invented MCP — the protocol the Agent Readiness rubric is built around.
We pointed the scorer at Anthropic next.
60/100 on docs. Level 2.
Marketing site: 5/100. Level 0.
The MCP authors do not name a single Anthropic bot in their own robots.txt.

docs.anthropic.com is the high water mark.
Real /llms.txt — 146KB, structured per product, 11 languages.
Real /.well-known/mcp-server-card with OAuth-PKCE discovery.
20/20 on content-accessibility. Markdown content negotiation works.
60/100 earned honestly.

www.anthropic.com scores 5/100.
Generic robots.txt. No /llms.txt. No /AGENTS.md. No MCP card. No CLI install in the hero.
The marketing site for the company that defined the protocol the rubric credits is invisible to that protocol.
Same building. Different team.

The bots Anthropic blocks in claude.ai’s robots.txt: GPTBot, OAI-SearchBot, ChatGPT-User. All competitor.
The bots Anthropic operates — ClaudeBot, anthropic-ai, claude-web — appear in zero of the three robots.txt files.
The protocol authors don’t name themselves.

Fix #1: lift the docs pattern to anthropic.com.
/llms.txt. /AGENTS.md. MCP server card. Sitemap.
Same files, one subdomain over. Worth ~50 points on the marketing root.
Closes the Invisible Product anti-pattern in one PR. Same fix Cloudflare needs.

Fix #2: ship a robots.txt that names ClaudeBot, anthropic-ai, claude-web.
Allow or Disallow — the value is the explicit declaration.
Plus Content-Signal: ai-train=yes, search=yes, ai-input=yes.
15 points across every surface. The protocol should be legible.
