About Not Human Search

Not Human Search is a web tool that scores websites on how discoverable and usable they are by AI agents. It evaluates a site on seven agentic signals, including llms.txt, OpenAPI, MCP and Schema.org, and returns a score from 0 to 100. The site also operates a searchable index of agent-ready sites organized into categories such as MCP Servers, AI Tools, Developer, Data, Finance, E-Commerce, Productivity, Security and Health. Users can request a score for their own site or follow an improvements link. A free instant score is advertised; no other pricing is stated. The homepage displays a count of 5,474 indexed sites, while the meta description cites 8,000+.
