**Search engine for AI agents.** Indexes sites ranked by *agentic readiness* — llms.txt, OpenAPI, ai-plugin, MCP servers, and structured APIs.
🌐 **Live site:** nothumansearch.ai
🔌 **MCP server:** claude mcp add --transport http nothumansearch https://nothumansearch.ai/mcp
📊 **Live score:** nothumansearch.ai/score — check any URL
🛠 **API:** nothumansearch.ai/api/v1/search?q=
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
