11 Emerging Security Risks With MCP and How Post-Quantum Standards Can Help
Gopher Security, Thursday, July 16th, 2026
Eleven security risks in Model Context Protocol deployments are examined alongside post-quantum cryptography as a mitigation path.
The Model Context Protocol has become central to enterprise AI operations, but its persistent, stateful connections create gaps that traditional tools like WAFs cannot address.
Shadow MCP deployments, meaning unauthorized server instances, operate outside security oversight and introduce unmonitored access points.
The article categorizes risks across transport, authorization, input/output, and compliance domains, flagging Harvest Now, Decrypt Later attacks in which adversaries collect encrypted traffic for future quantum decryption.
It recommends lattice-based quantum-resistant cryptography via hybrid wrappers rather than wholesale infrastructure replacement.
