About AI2Web
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.
