@coinbase publishes the protocol agents will use to pay each other (x402).
Three MCP servers in production. AgentKit. Agentic Wallet. CDP CLI.
35/100. Level 2.
One subdomain works. Two don’t. The marketing homepage where humans first meet Coinbase: 10/100, Level 0.

docs.cdp.coinbase.com is the high water mark.
The /llms.txt names every agent surface by name: Agentic Wallet MCP, CDP CLI MCP, AgentKit, x402, Server Wallets, Embedded Wallets.
21 mentions of “agent.” 13 of “MCP.” 17 of “Wallet.” 3 of “x402.”
Most agent-fluent llms.txt we’ve scored.

The surprise: www.coinbase.com/llms.txt is genuinely well-written.
“You’re on the consumer page. Authoritative docs are at docs.cdp.coinbase.com. If you want a wallet FOR an agent, start with Agentic Wallet.”
5KB of plaintext doing more for agents than 1.3MB of homepage HTML.

Fix #1: ship /.well-known/mcp-server-card from coinbase.com. Reference it from the homepage hero.
Three MCP servers already live in production.
An agent reading coinbase.com cannot tell. The capability is real. The discovery breadcrumb isn’t.
Worth 30 points everywhere.

Fix #2: lift /llms.txt to developers.coinbase.com. Ship /AGENTS.md on all three surfaces.
www.coinbase.com has /llms.txt. docs.cdp.coinbase.com has /llms.txt. The legacy developer entry point doesn’t.
Same company, three different stories about how to talk to agents.

Fix #3: per-named-bot blocks in www.coinbase.com/robots.txt.
GPTBot. ClaudeBot. anthropic-ai. Google-Extended. PerplexityBot. CCBot.
Choose to allow, disallow, or rate-limit each one. Either named-bot rules or Cloudflare Content Signals earn the 15 points.
