TL;DR: Opal Security says its rebuilt MCP servers keep access data inside customer boundaries, split end-user, provisioning, and auditing duties, and add approval handling inside the conversation flow, reframing agent access governance around scoped, reviewable runtime decisions. The control problem is no longer whether agents can act, but whether every action remains policy-bound, attributable, and contestable in session.
Editorial analysis by NHI Mgmt Group, based on content published by Opal Security: “What's new in Opal's MCP servers: self-hosted, scoped, and approval-ready”.
Key questions
Q: How should security teams design MCP server access for AI agents?
A: Security teams should design MCP access around a small set of agent goals, not a mirrored list of REST endpoints.
Q: What happens when MCP approvals happen outside the workflow?
A: Approvals outside the workflow tend to lose context, create delays, and weaken the evidence trail for later review.
Q: When does an MCP server become an overprivileged access path?
A: An MCP server becomes an overprivileged access path when it exposes more tools or administrative functions than the underlying role should have.
Practitioner guidance
- Define MCP trust boundaries before deployment Decide whether the server will be vendor-hosted, self-hosted, or split across environments, then map where access data, request context, and logs will reside.
- Split MCP capabilities by governance role Keep end-user access requests, admin provisioning, and auditing on separate server surfaces so each role has a different permission set and evidence path.
- Require server-side approval logging Make every approval or denial produce a durable record that binds the actor, policy decision, and exact request state at the time of approval.
Bottom line: MCP servers now function as governance surfaces, because they sit directly in the path between an AI client and the systems it can affect.

Opal Security's full blog post covers the operational detail this post intentionally leaves for the source:
- Command examples for configuring the end-user, provisioning, and auditing MCP servers
- Setup notes for self-hosted deployments, including environment and token handling
- Client-specific installation steps for Claude Code, Cursor, Gemini CLI, and other MCP clients
- The full tool list and documentation references for each server role

MCP access governance is becoming an identity boundary, not a transport detail. When an agent asks for data or takes action through MCP, the server is now part of the authorization path. That shifts the control question from connectivity to governance, because the server decides which identities, tools, and approval states can interact. Practitioners should treat MCP servers as governed access surfaces, not neutral plumbing.
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.
A question worth separating out:
Q: How do security teams know whether MCP server governance is working?
A: They should be able to answer four questions at any time: what servers exist, which are official, what credentials they can use, and what systems they contact. If those answers are unclear, governance is not working. The signal is not just fewer alerts, but clear attribution and scoped access across the fleet.
