Quantum-Resistant Cryptography Proposed for MCP Agent Memory Protection

Security Boulevard published analysis (May 1) arguing that MCP deployments need a 'PQC Bridge' — a security proxy implementing quantum-resistant cryptographic handshakes between agents and MCP servers — to protect agentic memory from both current manipulation and future quantum decryption threats. The proposal combines post-quantum cryptography with zero-trust architecture requiring continuous identity-based verification and policy-as-code enforcement for every MCP server call. While forward-looking, this signals that the MCP security discussion is shifting from patching today's vulnerabilities to hardening the protocol's cryptographic foundations.
