Why can an MCP gateway still leave governance gaps?

An MCP gateway can help centralize access to tools, but it may not solve the full governance problem by itself. Enterprises also need to know which agent is acting, which workflow produced the request, whether the agent has least-privilege access, how policy is enforced between components, and what audit trail exists after the call. A gateway often controls an entry point; agent governance also includes workload identity, tool-level authorization, data boundaries, and execution evidence. Diagrid's strategy treats MCP security as part of a broader production platform, not just a gateway or connector problem.
