Covers implementing hybrid post-quantum cryptography (PQC) by layering NIST-standardized ML-KEM alongside classical ECDH within TLS 1.3. Walks through a four-step implementation process: inventorying MCP endpoints, selecting NIST algorithms (ML-KEM, ML-DSA), deploying a transparent mcp-context-protector wrapper, and automating key rotation. Addresses performance trade-offs, federal compliance requirements coming in June 2026, and includes a case study of a firm securing 50+ MCP endpoints in 30 days. ## Full article daily.dev links to this article rather than hosting it.
