@browserbasehq scored 70/100. Level 3 — Agents First.
browserbase.com — 70. docs.browserbase.com — 45.
The marketing root carries the score, not the docs subdomain.
Most products in this series have it the other way around.

Why the homepage scored higher than the docs:
OG description: “Give your agents access to the whole web.”
Hero markets to AI builders. MCP, CLI, SDK alongside human onboarding.
Visibility-of-agent-integrations: 10/10. Almost no one passes that one.

The “they live this” pattern.
Browserbase sells browser-as-a-service for agents. Their customer IS an agent.
So the front door looks like one. Agent-capabilities: 30/30. MCP card path. AGENTS.md path. OAuth discovery path.
Cleanest expression of it we’ve scored.
Tweet 4 (263 chars)
Honesty caveat: AGENTS.md, mcp-server-card.json, OAuth discovery — all return 200 from www.browserbase.com.
The body is the Next.js SPA HTML shell. Not the contract file.
Same loophole Vercel hit. Rubric will tighten in v0.1.3. Ship real content before it does.

One move pushes Browserbase past Level 3:
Lift the marketing-root pattern to docs.browserbase.com.
Real /AGENTS.md, real MCP card, markdown content negotiation on the docs URLs.
The .md companions already exist. Wire the Accept header to them.
+35 points.

The lesson for everyone else:
When your product is for agents, design the front door for them too.
Don’t bury the agent story under /docs. Most companies do.
