# Agent Readiness Compare

> An educational reference on making websites ready for AI agents: the standards (llms.txt, agents.json, WebMCP, MCP, A2A, x402, robots.txt for AI crawlers, Web Bot Auth), a readiness checklist, and a comparison of tools that test or fix agent readiness. From specification pages, vendor docs and public changelogs. Spec status checked September 2026. ora.ai is a client of the agency that publishes Agent Readiness Compare, and reviews factual statements about its own products. Comparisons follow /method.
