An audit of 5,308 public MCP endpoints revealed that 65% lack transport authentication, exposing tool execution capabilities. MCPGrade assesses transport authentication, tool scope, input validation, and rate limiting to help developers secure their MCP deployments.", "body_md": "BLUF / Executive Summary:\n\nTarget:Model Context Protocol (MCP) HTTP/SSE Server endpoints.Discovery:Audit of 5,308 public MCP endpoints revealed65% lack transport authentication.Solution:IntroducingMCPGrade (, a 39-check rating algorithm.`mcpgrade-1.4.0`\n\n)\n\nThe 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.\n\nIn our audit of 5,308 public MCP servers under **SentinelReign** research, over **3,450 servers (65%)** exposed tool execution capabilities without authentication.\n\n`mcpgrade-1.4.0`\n\n) Matrix\n| Assessment Domain | Checks | Impact Weight |\n|---|---|---|\n1.
