Lattice-based PQC for MCP Transport Layer Security

The article argues that MCP-based AI systems face harvest-now-decrypt-later and manipulation risks and recommends making MCP transport quantum-safe by adopting NIST PQC (FIPS 203 ML-KEM for key exchange and ML-DSA for signatures), integrating a Gopher Security 4D framework for context-aware controls, and enforcing policy and behavioral monitoring to detect tool poisoning and puppet attacks; it also covers implementation trade-offs (larger keys, latency/MTU tuning, liboqs usage), operational guidance (key management, parameter-level access control), and scaling/compliance considerations (hardware acceleration, hybrid crypto) for building resilient, post-quantum AI infrastructure.
