MCP Security for Enterprise Organizations: Real-world experiences and advanced defense
Article Brief
Why this article matters
MCP is being called the 'USB for AI'—but that universality is exactly what makes it a rich attack surface. This post catalogs the concrete threats (tool poisoning, RCE via powerful runtimes, prompt injection raids from ingested data, supply-chain typosquatting) and maps each to enterprise-grade defenses: Firecracker/gVisor isolation, ephemeral filesystems, zero-trust auth with mTLS and vault-backed secrets, and validation/rate-limit layers. You get a zoned reference architecture and curated links to the papers and tooling behind each recommendation.
