## Detailed info

## What is AI2Web?

AI2Web is an open protocol and interoperability layer that makes website capabilities accessible to AI assistants without HTML scraping.

## What AI2Web does

The system lets websites describe capabilities once in a single manifest. AI assistants discover the manifest through well-known discovery endpoints and execute actions across MCP, ACP, and REST transports.

## How AI2Web works

Publish a manifest at /ai2w, add the discovery anchor at /.well-known/ai2w, and validate the site using the validator CLI or browser tool.

## Key features

- Single capability manifest published at /ai2w describes site actions and content.
- Discovery anchor at /.well-known/ai2w enables automated assistant detection.
- Supports multiple protocols by connecting through MCP, ACP, and REST transports.
- CLI and in-browser validator scores manifest readiness out of 100.
- Open-source reference SDKs available for TypeScript, JavaScript, Python, PHP, Go, Ruby, and WordPress.
- Consent controls let sites require user approval before high-risk actions run.
