The Current State of MCP Server Security and AI Agent Attack Surface in Late 2025 As we approach mid-2026, the landscape around Model Context Protocol (MCP) server security and the burgeoning AI agent attack surface has shifted dramatically. What began as a promising framework for AI interoperability has, predictably, become a new front for threat actors. The pervasive adoption of generative AI models across enterprise IT has profoundly expanded what I consider a "context-aware" perimeter. Organizations, largely driven by pressing business needs and the "AI-first" mandate, often rushed into deployments, focusing on functionality over robust security architecture. Many of these 초기 MCP server implementations, particularly the ones that went live in late 2024 and early 2025, were built with permeable trust boundaries, assuming internal network benignity. This assumption is, as we've repeate
