AGMP Partners The Current State of MCP Server Security and AI Agent Attack Surface in Late 2025 As of May 21, 2026, the proliferation of AI-powered tools across enterprise environments has fundamentally reshaped our operational security landscape. What we’re seeing isn't just about integrating LLMs; it's about embedding intelligent agents, often autonomously, deeper into mission-critical workflows. The Model Context Protocol (MCP), initially conceived to standardize the exchange of contextual information between AI models and their supporting infrastructure, has become a pivotal, albeit double-edged, sword. While MCP significantly improves AI model performance and adaptability by providing rich, real-time operational context—think of it as giving the AI agent a constantly updated briefing—it simultaneously expands the lateral movement surface in ways we’re only now fully grasping. The th
