Viper vs McpVanguard

Viper: VIPER is a powerful and flexible red team platform designed for adversary simulation and cybersecurity assessment. It integrates core tools, an LLM agent, and over 100 post-exploitation modules to efficiently complete red team operations.; McpVanguard: McpVanguard is a security gateway for MCP agents that inspects traffic in real time and enforces security policy before sensitive calls reach the underlying tool. It works in local-first mode wrapping stdio MCP servers and in gateway mode exposing hardened SSE and Streamable HTTP endpoints. Transparent integration without rewriting existing MCP servers.
