The NSA's Artificial Intelligence Security Center published a Cybersecurity Information Sheet on May 20 covering security design considerations for AI-driven automation leveraging MCP. The guidance identifies gaps in MCP design and implementation — including serialization risks, trust boundaries, implicit trust relationships, dynamic tool invocation, and agent misuse — and notes that traditional cybersecurity principles do not adequately address agentic AI systems using MCP. The NSA specifically calls out that real-world MCP adoption has accelerated across legal, finance, software development, and other high-stakes industries handling personally identifiable information. For legal KM infrastructure, the guidance is directly material: any firm connecting AI agents to governed knowledge repositories via MCP needs to treat the agentic environment as a security continuum, not a series of patchable endpoints.
