Why it matters
MCP gateways connect AI agents to enterprise tools and data without native access controls, making governance gaps a real avenue for tool abuse and sensitive-data exposure that defenders must address.
Barndoor's blog outlines security requirements for enterprise MCP (Model Context Protocol) gateways, arguing that most MCP deployments lack access controls and identifying five gaps: all-or-nothing tool permissions, no user scoping, silent vendor-side changes, fragmented policy across AI clients, and unfiltered sensitive data. It recommends per-tool policy enforcement, IdP-driven identity, change management, and a default-deny posture.
