**Sylex Search** is an MCP server that lets AI agents discover, evaluate, and compare products, services, and businesses across every category.
Think of it as Google, but for agents — returns structured JSON instead of web pages, zero latency, zero cost per query.

Why this exists
McKinsey projects $1 trillion in sales will flow through AI agents. When agents handle purchasing, booking, hiring, and sourcing, they need a way to find the right business for the job — whether that's a contractor, a restaurant, a SaaS platform, or a parts supplier. If a business isn't in the index, it's invisible to agents.
Sylex Search is the discovery layer for agent commerce.
