Treat MCP as critical infrastructure

The Model Context Protocol is effectively becoming the TCP/IP of the agentic AI era. As we have seen with the recent vulnerabilities in major MCP servers, treating these connections as trusted pipelines is a recipe for compromise. Security teams must immediately move to inventory their MCP integrations, apply rigid sandboxing, and treat every tool execution as a potential vector for indirect injection.
