TL;DR: Shared MCP infrastructure turns the proxy into a governed tool-use layer, Willow reports, where identity-aware authorization and action-level policy matter more than simple transport bridging. The proxy must enforce namespaces, approved registries, and audit trails before shared access becomes a broad blast radius.
Editorial analysis by NHI Mgmt Group, based on content published by Willow: “How to Scale Your MCP Proxy Server for Enterprise AI”.
Key questions
Q: What breaks when MCP traffic bypasses a central proxy?
A: You lose policy enforcement, session isolation, and complete audit evidence in one move.
Q: How do teams know whether their MCP gateway is actually controlling risk?
A: Look for evidence that the gateway can restrict tool discovery, block high-risk actions, and preserve a complete record of who requested what and why it was allowed or denied.
Q: How should security teams govern MCP tool access in enterprise environments?
A: Security teams should bind MCP tool access to enterprise identities, entitlements, and lifecycle state before a request reaches production tools.
Practitioner guidance
- Define action-level policy boundaries Separate read, write, export, delete, and production-changing tool actions before exposing shared MCP access to multiple teams.
- Centralize approved MCP servers Move shared upstream servers behind a managed gateway with namespaces, ownership, and a registry of approved tools.
- Bind every request to identity Use existing SSO, group membership, and lifecycle controls so each tool call is tied to a human identity or managed agent identity.
Bottom line: The article shows that shared MCP infrastructure changes the security problem from transport bridging to governed tool use.

Enterprise MCP governance is really a control-plane problem, not a transport problem. The article correctly shifts the debate away from stdio, HTTP, or SSE mechanics and toward who can discover, invoke, and modify actions through shared tool surfaces. Once multiple teams use the same proxy, the security question becomes whether the organisation can govern intent at runtime, not whether it can relay messages. That is the point where identity, authorization, and action policy become one control layer, and practitioners should stop treating the proxy as a simple integration utility.
A few things that frame the scale:
- 24,008 unique secrets were exposed in MCP configuration files in 2025 alone, the protocol's first year of widespread adoption, according to the State of Secrets Sprawl 2026.
- 19% of organisations give AI systems dramatically more access than human employees, nearly one in five granting unrestricted privilege, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: Should organisations use one gateway for all AI agents and LLM clients?
A: A single gateway can work if it is paired with namespaces, team-level tool bundles, and policy boundaries that prevent cross-team overexposure. Without those controls, one endpoint becomes a shared blast radius. The decision should be based on whether the gateway can preserve least privilege while keeping onboarding simple.
