Use Case Recommendations
Best for: Not Human Search
Not Human Search is a search engine whose users are meant to be agents, not people, and a scoring tool for anyone who wants to be found by them. It indexes thousands of sites and ranks them on machine-readable readiness rather than on backlinks or bids — the stated rule is that organic rank is based on readiness and never on payment. Readiness is scored 0–100 across agentic signals an autonomous client actually needs to transact: whether an llms.txt exists, whether there is an OpenAPI description, whether an MCP server is exposed, whether Schema.org markup is present, and several more. That produces two distinct uses. If you are building an agent, you can search by category, protocol or the job the agent needs to complete and get back services it can genuinely call rather than marketing pages it would have to scrape. If you run a site, you can score it and see specifically which machine-readable affordance is missing, which is far more actionable than a generic SEO audit because the checks map one-to-one onto files you can ship. Browsing is organised by category — MCP servers, AI tools, developer, data, finance, e-commerce, productivity, security, health — plus top-100 and newest views. Search and scoring are free.
Ideal use cases:
- •Teams or individuals who need 0–100 agent-readiness score across multiple machine-readable signals
