What it does
NotHumanSearch is a search engine whose index only contains sites that are actually usable by AI agents. Every indexed site must ship at least one real agent signal — llms.txt, ai-plugin.json, OpenAPI spec, MCP server, or a structured REST API with machine-readable schemas. Sites are scored on an agent-readiness scale and ranked so that the most agent-ready result wins, not the one with the most backlinks.
Where general web search returns HTML pages written for humans, NHS returns a ranked list of services an agent can immediately consume — with an agentic_score, the MCP endpoint URL if present, the llms.txt URL if present, and category tags already attached.
