TL;DR: Unosecur argues that Model Context Protocol shifts AI agent risk from obvious failures to silent drift in identity, trust, and privilege as agents persist and expand their scope over time. The real problem is lifecycle governance, because review cadences and static controls assume access stays stable long enough to be examined.
Editorial analysis by NHI Mgmt Group, based on content published by Unosecur: “MCP Security Checklist: Governing AI Agents in Production”.
Key questions
Q: What breaks when MCP agents are approved once and then left to evolve on their own?
A: The control model breaks because the agent’s effective scope can change after approval while the review process still assumes a stable permission set.
Q: Why do MCP and agentic AI increase the risk of silent privilege drift?
A: Because agents can keep operating legitimately while their context, reach, and tool combinations expand over time.
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.
Practitioner guidance
- Map every live agent to a named owner and scoped purpose Require a unique identity, an accountable owner, and a documented task boundary for each agent so that drift can be judged against something real.
- Inventory MCP servers, tools, and delegated access paths Maintain an automated inventory of trusted servers, attached tools, and inherited permissions so shadow or orphaned paths are visible before they expand.
- Replace static approval with runtime revocation capability Ensure credentials can be revoked, privileges can be adjusted, and kill switches can be used without redeploying the agent or waiting for a maintenance window.
Bottom line: MCP risk is best understood as lifecycle drift, where an agent’s effective authority grows beyond the original approval state.

Lifecycle governance is the real control plane for MCP. The article is right to reject the idea that this is mainly a tooling gap. MCP risk grows because identity, trust, and privilege change after deployment, while many programmes still govern agents as if access were static. That means the discipline has to move from one-time approval to continuous identity and behaviour governance.
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.
- Systems with least-privileged AI access had a 17% incident rate vs 76% for over-privileged systems. Organisations failing to scope AI access properly are 4.5x more likely to experience a security incident, according to the 2026 Infrastructure Identity Survey.
A question worth separating out:
Q: What is the difference between approving an MCP server and governing the agent that uses it?
A: Approving the server is a trust decision about one component. Governing the agent is a lifecycle decision about how identity, privilege, and behaviour change as that component is used over time. Teams need both, because an approved server can still support an unsafe agent lifecycle.
