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 supportAGENT_FRIENDLY(60-79) — Good API, minor gapsAGENT_POSSIBLE(40-59) — Usable with effortAGENT_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
