The Future of MCP Security: Why Quantum-Resistant Encryption is No Longer Optional

This post warns that rapid, unmanaged adoption of the Model Context Protocol (MCP) creates an invisible, high-privilege "shadow IT" layer and that adversaries are performing "harvest now, decrypt later" attacks on encrypted MCP traffic; it advises organizations to inventory MCP endpoints, prioritize long-lived/high-value data paths for hybrid post-quantum crypto (Kyber + Dilithium), adopt digital signatures for action integrity, and phase migration with hardware-accelerated libraries to mitigate performance impacts.
