your AI agent can actually use

Most tools are built for humans. Some work with agents. A few were designed for agents from day one. Agent Native Registry rates every tool on how well an AI agent can discover, authenticate, and use it end-to-end.

See how your tool scores against our 33-point checklist.

What we score

Agent Native Score — a checklist, not a vibe

Every tool is scored against the same 33-point checklist. Pass/fail. No AI-generated numbers. Fully auditable.

Discovery

OpenAPI spec, llms.txt, MCP server, public docs, code examples, changelog, status page

Auth

No CAPTCHA, no phone verify, API key auth, no manual approval, no billing required, no org setup

Pricing

Free tier, usage-based pricing, no minimum contract, public pricing, sufficient free tier, sandbox mode

Agent Tooling

account required

SDKs, structured errors, idempotency, pagination, webhooks, rate limit headers, consistent naming

Reliability

account required

Meaningful errors, retry-after headers, uptime SLA, graceful degradation, request IDs, versioned API, sandbox

19 checks are publicly verifiable. 14 checks require testing the API — coming soon. Score = points earned / 33 total, so tools max out around 58% until fully evaluated.
