The post catalogs MCP-specific vulnerabilities across five layers: transport/communication (insecure TLS, replay attacks), authentication/identity (static keys, token delegation flaws), context integrity (poisoning, hijacking, leakage), authorization/privilege (overbroad permissions, lateral movement), and supply chain (malicious tool descriptors, shadow services). Defensive strategies include identity-first secretless authentication, context validation at every boundary, least-privilege enforcement, runtime anomaly detection, and supply chain scrutiny. The post concludes by promoting Aembit's Workload IAM platform as a solution that brokers just-in-time scoped access using cryptographic workload attestation. ## Full article daily.dev links to this article rather than hosting it.
