An Agentic Resource Discovery (ARD) manifest is a JSON file, served at /.well-known/ard.json, that lists the tools and services AI agents can use from your organization, such as MCP servers, agents and skills. Registries crawl these files so agents can find, verify and connect to capabilities across the web.

Agentic Browsing is a new, experimental category in Google Lighthouse that checks how easily AI agents can understand and use your website. It looks at WebMCP tools, accessibility, layout stability, llms.txt and an ard.json manifest. It has no 0–100 score, and Google does not tie it to search rankings.
