MCPGrade 소개: 2026년 모델 컨텍스트 프로토콜 서버 보안

BLUF / Executive Summary:

• Target: Model Context Protocol (MCP) HTTP/SSE Server endpoints.
• Discovery: Audit of 5,308 public MCP endpoints revealed 65% lack transport authentication.
• Solution: Introducing MCPGrade (mcpgrade-1.4.0), a 39-check rating algorithm.

The Model Context Protocol (MCP) is now the standard for connecting AI models to tools and data. But as developers deploy MCP servers, security has lagged.

In our audit of 5,308 public MCP servers under SentinelReign research, over 3,450 servers (65%) exposed tool execution capabilities without authentication.
