## About

# Not Human Search

[](https://nothumansearch.ai/site/nothumansearch.ai)

**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](https://nothumansearch.ai)
🔌 **MCP server:** `claude mcp add --transport http nothumansearch https://nothumansearch.ai/mcp`
📊 **Live score:** [nothumansearch.ai/score](https://nothumansearch.ai/score) — check any URL
🛠 **API:** [nothumansearch.ai/api/v1/search?q=](https://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

## 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  |
