Securing Model Context Protocol: A Roadmap for Post-Quantum AI Infrastructure

This post warns that the dynamic, agent-driven Model Context Protocol (MCP) is vulnerable to future quantum-enabled 'store now, decrypt later' attacks and present runtime threats like schema manipulation and cross-agent poisoning; it recommends hybrid PQC/classical encryption, agent-to-agent trust frameworks, schema validation middleware, and a phased roadmap (assessment → hybrid transition → full post-quantum) to mitigate risk.
