AGMP Partners The Current State of MCP Server Security and AI Agent Attack Surface in Late 2025 As we push past mid-2026, the landscape around Model Context Protocol (MCP) server security and the expanded attack surface presented by AI agents has fundamentally shifted. When MCP began gaining traction a couple of years ago as the de facto standard for inter-service communication within large AI model deployments, many organizations, my own included, were hyper-focused on classic perimeter defenses and API gateway hygiene. We thought we had a handle on it. But what's become acutely clear is that MCP doesn't just enable distributed model inference; it fundamentally alters the lateral movement paradigm within an AI-powered enterprise. The threat actors, bless their relentless efficacy, have already weaponized this. We're seeing novel attack vectors that leverage context poisoning, model stat
