Five key pillars are outlined for securing these systems: (1) conducting a cryptographic inventory to map all vulnerable data streams; (2) adopting a hybrid ECC + ML-KEM approach for layered protection; (3) building crypto-agility so algorithms can be swapped via configuration rather than code changes; (4) securing Model Context Protocol transport layers with validation wrappers against tool poisoning; and (5) implementing continuous governance and behavioral monitoring. A phased implementation roadmap is recommended, starting with highest-traffic nodes and scaling after validating a hybrid pilot. ## Full article daily.dev links to this article rather than hosting it.
