Every MCP Server Failed: How AI Agent Security Testing Exposed a Critical Industry Gap

Traditional web application security testing cannot address AI agents communicating through MCP, exposing a critical gap as these systems gain production deployment. The first Agent DAST scanner tested public MCP servers across eight security dimensions and found every one vulnerable—with missing authentication, unsigned messages, and zero rate limiting among the endemic failures. This reveals that AI agent security requires entirely new testing frameworks beyond legacy DAST approaches.
