Is Your AI Model Context Protocol Ready for Quantum Computing Security Challenges?

This blog-style analysis warns that MCP (Model Context Protocol) traffic is at risk from 'Harvest Now, Decrypt Later' (HNDL) attacks—where adversaries silently capture encrypted agent context today to decrypt it once quantum computers exist—and urges organizations to adopt NIST post-quantum cryptography via hybrid key exchanges, quantum-hardened short-lived tokens, and a phased audit checklist to harden MCP deployments against future quantum-enabled threats.
