Not Human Search

Search engine for AI agents. Indexes sites ranked by agentic readiness — llms.txt, OpenAPI, ai-plugin, MCP servers, and structured APIs.

Why

LLM agents and autonomous systems can't "browse the web" efficiently the way humans do. They need machine-readable signals — llms.txt, OpenAPI schemas, MCP endpoints, ai-plugin manifests. NHS is the first search engine that explicitly ranks by how agent-friendly a site actually is, not by traditional SEO.

What's indexed

• 1,900+ agent-first sites scored across 7 agentic signals (see /api/v1/stats for current live count)
• 500+ MCP servers with live JSON-RPC probe verification
• Agent-first filter — every indexed site has at least one strong agent signal (llms.txt, ai-plugin, OpenAPI, structured API, MCP server)
• Continuously refreshed via daily recrawl + weekly auto-discovery pipeline

Scoring (max 100)

| Signal | Points | |----------------|--------| | llms.txt | 25 | | ai-plugin.json | 20 | | OpenAPI spec | 20 | | Structured API | 15 | | MCP server | 10 | | robots.txt | 5 | | Schema.org | 5 |
