TL;DR: MCP proxies centralise authentication, policy enforcement, logging, and session control for Model Context Protocol traffic, according to Obot’s analysis, because direct client-to-server connections create blind spots as remote MCP deployments multiply. The governance question is now whether enterprises can scope, inspect, and audit MCP access before sprawl turns AI connectivity into unmanaged identity risk.
NHIMG editorial — based on content published by Obot: MCP proxy control for enterprise AI access
By the numbers:
- Only 18% of MCP server deployments implement any form of access scoping for tool permissions.
- 53% of MCP servers expose credentials through hard-coded values in configuration files.
Questions worth separating out
Q: How should security teams govern MCP in enterprise environments?
A: Treat MCP as an identity and authorization problem first.
Q: Why do MCP tool pickers create governance risk even when users stay in control?
A: Tool pickers can turn one-off access into repeatable authority patterns.
Q: What breaks when MCP access is not centrally enforced?
A: When MCP access is not centrally enforced, agents can bypass the sanctioned protocol and reach the same data through alternative connectors or direct application paths.
Practitioner guidance
- Define the MCP proxy as an identity control point Map the proxy into IAM and NHI governance, then require authentication, authorization, and audit logging at that layer before any server is exposed.
- Separate tool discovery from tool execution Apply policy before tool definitions are presented to clients, and filter upstream tools by names, scopes, and business context to reduce prompt injection and context leakage.
- Bind proxy access to enterprise identity systems Integrate the proxy with existing identity platforms such as Okta or Microsoft Entra so access decisions reflect role, team, and server-specific policy.
What's in the full article
Obot's full article covers the operational detail this post intentionally leaves for the source:
- How the MCP Gateway implements proxy-based control across remote MCP servers and client sessions
- Details on policy enforcement using OPA Rego, OAuth 2.1, RFC 8693 token exchange, and personal access tokens
- Support for multiple transports, including Streamable HTTP, stdio, and Server-Sent Events
- Operational examples of request tracking, connection pooling, and server registry management at scale

MCP proxying is becoming the governance boundary for agent-to-tool access. The article makes clear that direct client-to-server MCP connections create blind spots in authentication, authorization, and logging. For identity teams, that means the proxy is not an optional optimization but the layer where NHI-style controls are actually enforced. The practitioner conclusion is simple: if MCP traffic is not centrally mediated, it is not centrally governable.
A few things that frame the scale:
- Only 18% of MCP server deployments implement any form of access scoping for tool permissions, according to the State of MCP Server Security 2025.
- 53% of MCP servers expose credentials through hard-coded values in configuration files.
A question worth separating out:
Q: How do audit and telemetry requirements change when MCP becomes part of the AI stack?
A: Audit data becomes part of the identity record because it shows who accessed which server, what they invoked, and when. Teams need to control access to those logs as tightly as they control the servers themselves, since logs may contain sensitive prompts, tool details, or credentials. That creates a second governance layer around the evidence store.
