The "describe once, every agent can use it" framing lands on the real problem — but the hard part isn't emitting the description, it's that agents don't yet reliably fetch or honor a site-declared manifest. Curious whether you're leaning on an emerging convention (llms.txt, schema.org actions) or a proprietary format? That choice is what decides whether "every agent" is real or aspirational — a standard the crawlers already read gets you there; a new format means waiting on adoption.
Quick update for everyone who supported the AI2Web launch: the AI2Web AI Readiness Checker is now live on the Chrome Web Store. Click the icon on any site and you will see its AI Readiness Score, tier, and the exact capabilities it is missing for AI agents. It is the fastest way to check a site without leaving the page. Free, private (only the current tab's origin is sent to score it), no accounts. https://chromewebstore.google.com/detail/ai2web-ai-readiness-check/dgfgbjlpmhahoafdcfandobbncfjhlle Thanks again for the feedback here, a lot of it shaped where this is going.
AI2Web provides an open interoperability layer that lets websites expose a single capability manifest for AI agents across multiple protocols.

AI2Web FAQ
Is AI2Web just the MCP for websites?+
No. It sits above protocols, providing discovery, validation, governance and analytics in addition to MCP, ACP, REST, etc.
Do I need to rebuild for each AI assistant?+
No. Publish one manifest at /ai2w and AI2Web serves it in the protocol each assistant understands.
Is AI2Web open and what does it cost?+
It is free and open source; the spec is CC-BY 4.0 and SDKs are MIT licensed.
How do agents discover my site?+
Through a required /.well-known/ai2w anchor that points to the manifest; SDKs also emit /.well-known/agent.json and /llms.txt projections.
Is it safe for agents to perform actions?+
Yes. High-risk actions require preview, consent and OAuth2 + PKCE; credentials are never sent cross-origin and an SSRF guard is applied.
Which languages and platforms are supported?+
SDKs are available for TypeScript/JavaScript, Python, PHP, Go, .NET, Ruby, plus a WordPress plugin and Chrome extension.
