Hardening AI Data Security: Implementing Quantum-Resistant Cryptography in MCP Environments

This blog post warns that MCP-based AI agent architectures expose sensitive data through a vulnerable transport layer and long-lived storage—creating immediate risks (context poisoning, over-privileged tokens) and a long-term 'store now, decrypt later' threat from future quantum capabilities. It advocates adopting NIST post-quantum standards (FIPS 203/204/205), hybrid handshakes, crypto-agility, stronger mTLS configurations, and periodic audits to remediate these risks.
