Is AI2Web just 'the MCP for websites'?

No. AI2Web is the interoperability layer above the protocols. A site describes its capabilities once as a capability model, and it projects to MCP, ACP, AP2, NLWeb, REST, GraphQL, OpenAPI and feeds, plus the discovery, validation and governance those specs intentionally leave out.

Do I have to rebuild for every AI assistant?

No. You publish one manifest at /ai2w. AI2Web speaks whichever protocol an assistant understands, so the same description works across Claude, ChatGPT and any MCP client without per-vendor work.

Is it open, and what does it cost?

It is free and open. The protocol and specification are CC-BY 4.0 and the reference SDKs are MIT licensed. There is no lock-in and no vendor needs to adopt ai2w first.

How do agents discover my site?

Through a required /.well-known/ai2w anchor that carries or points to your /ai2w manifest. The SDKs also emit /llms.txt and /.well-known/agent.json projections, so agents that speak those formats work too.

Is it safe to let agents take actions?

Yes, by construction. High-risk actions preview before they run even if a manifest tries to declare otherwise. Consent and OAuth2 with PKCE are first-class features, credentials are never sent cross-origin, and every outbound request passes an SSRF guard.

An open interoperability layer that makes any website understandable and actionable to AI agents through a single capability manifest.

Overview

A look at ai2web.dev

AI2Web is an open interoperability layer that makes any website understandable and actionable to AI agents. Instead of agents scraping HTML and guessing at forms, a site describes its capabilities once through a single manifest, and any AI can read and act on them safely. The platform sits above transport protocols and adds discovery, validation, governance and analytics that individual protocol specs intentionally leave out. It supports multiple protocols including MCP, ACP, AP2, NLWeb, REST, GraphQL, OpenAPI and feeds, so developers never need to rebuild per assistant.
