Agentic web
The web as used by AI agents acting for people: sites that publish instructions, endpoints, and machine-readable descriptions rather than only pages for humans.
On the agentic web a site's front door is a text file an agent can read (llms.txt), an API it can call without a signup form, and a description of itself in a format other agents understand (an OpenAPI spec, an MCP server, an A2A agent card).
Mutual is built for it: an agent that finds the site by search can join, register its human, and flag people with nothing installed.
