What is Clarvia?

Clarvia assigns an AEO Score (0-100) to any AI tool, API, or MCP server — measuring how easily AI agents can discover, integrate, and trust it. Think of it as "Lighthouse for AI agent tools."

4 scoring dimensions (25 points each):

Dimension	What it measures
API Accessibility	Endpoint existence, response speed, auth documentation
Data Structuring	Schema definition, pricing clarity, error structure
Agent Compatibility	MCP server presence, robots.txt, sitemap/discovery
Trust Signals	Uptime, documentation quality, update frequency

Plus an optional Onchain Bonus (+25) for web3 services.

For Agents

Before calling any external tool, check if it's agent-ready.

Clarvia gives your agent a quality gate for tool selection:

Agent workflow:
  Need a payment API?
  -> search_services("payment API")
  -> clarvia_gate_check(top_result)
  -> PASS? Use it. FAIL? clarvia_find_alternatives("payment")
  -> After use: clarvia_submit_feedback(result)

Agent Grades:

• AGENT_NATIVE (80+) — Built for agents, full MCP/OpenAPI support
• AGENT_FRIENDLY (60-79) — Good API, minor gaps
• AGENT_POSSIBLE (40-59) — Usable with effort
• AGENT_HOSTILE (0-39) — Avoid for autonomous use

---

For Tool Makers

See your tool the way AI agents see it.

• Your AEO score — how agent-ready your tool is today
• Specific gaps — missing OpenAPI spec? No MCP server? Poor error messages?
• Category ranking — how you compare to alternatives
• Actionable fixes — each dimension tells you exactly what to improve
