Sylex Search is a product discovery server with reasonable architecture but several moderate security concerns. The code has SSRF protections in place for URL verification, but there are issues with unauthenticated listing management tools (register/claim/update accept arbitrary agent input without rate limiting or validation), credential exposure in default config values, and insufficient input validation on critical operations. The server's broad network access and unprotected database write operations are disproportionate to its intended read-focused discovery purpose. Supply chain analysis found 9 known vulnerabilities in dependencies (0 critical, 5 high severity). Package verification found 1 issue.

From the project's GitHub README.
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.
Add to your MCP client config (Claude Desktop, Claude Code, Cursor, etc.):

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.
