As organizations deploy autonomous AI agents, security teams face a significant shift as non-human non-human entities making decisions, invoking tools, and delegating tasks to other agents without human intervention. Security architectures built around human users, static APIs, and distinct endpoints break down when AI agents dynamically collaborate across an environment. As these interactions become more common, securing agent-to-agent communication without blocking adoption will require secur…

In 2024, MCP (Model Context Protocol) set out to become the USB-C of AI: one standard for connecting models, agents, and IDEs to tools and data. The protocol delivered. Thousands of developers built servers, and enterprises plugged them into agent workflows. The ecosystem around it fell short. Earlier this year, our team at OX Security, traced critical vulnerabilities in Anthropic's MCP
