Check if AI agents can discover, authenticate, and interact with your site. We test 14 key protocols — robots.txt, MCP, API catalog, OAuth, WebMCP, Content-Signal, commerce protocols, and more.
No signup required. Instant results.
AI agents use these standardized protocols to discover, authenticate, and interact with websites. Each one improves your visibility in the agentic web.
Proper robots.txt tells AI agents what they can access on your site.
Content-Signal directives in robots.txt declare AI training and content usage preferences.
A valid sitemap.xml makes your pages discoverable by AI crawlers and agents.
HTTP Link headers point agents to API catalogs, documentation, and alternative formats.
/.well-known/api-catalog advertises your machine-readable API endpoints for automated discovery.
/.well-known/openid-configuration lets agents discover how to authenticate with your APIs.
/.well-known/oauth-protected-resource (RFC 9728) tells agents which authorization servers can issue tokens.
/.well-known/mcp/server-card.json describes your Model Context Protocol tools and capabilities.
/.well-known/agent-skills/index.json lists capabilities an AI agent can perform on your site.
Responding with text/markdown when requested allows AI agents to efficiently parse your content.
WebMCP exposes site tools to AI agents via browser using navigator.modelContext API.
x402 enables AI agents to make HTTP-native payments for accessing premium content or APIs.
/.well-known/ucp declares commerce capabilities and payment endpoints for agent transactions.
/.well-known/acp.json enables agents to discover your Agentic Commerce Protocol implementation.

From ChatGPT plugins to autonomous browsing agents like Manus and Devin, AI is becoming a significant traffic source. Gartner predicts 30% of web sessions will involve an AI agent by 2026.
OAuth, OIDC, and MCP discovery let you control how agents interact with your site — authenticated, rate-limited, authorized, and auditable. Stay in control of agent access.
RFC 9727 API catalogs let agents find and use your APIs automatically. Companies with agent-discoverable APIs see 40% more integrations and new revenue channels.
Early adopters of agent readiness will be included in AI recommendations and tool-use workflows. Your competitors that remain invisible to agents will lose this traffic forever.
