TL;DR: MCP identity orchestration links AI agents to tools and data sources, which makes access control, session trust, and privilege scoping central to agent governance, according to Descope. The issue is not whether agents can connect, but whether their identity and authorization model can be constrained enough to prevent unintended actions.
NHIMG editorial — what this means for NHI practitioners
Questions worth separating out
Q: How should security teams govern AI agent identities in MCP workflows?
A: Treat each agent as a governed non-human identity with an owner, task scope, expiry window, and revocation path.
Q: What is the difference between authenticating an AI agent and authorising it?
A: Authentication proves the agent is known to the system, while authorisation limits what that agent can do after it is admitted.
Q: When does JIT access help AI agent security, and when does it fall short?
A: JIT access helps when credentials are tightly bound to a single task and expire before the agent can reuse them elsewhere.
Practitioner guidance
- Define agent identity ownership Assign a named owner for every MCP-connected agent, including approval authority, risk acceptance, and offboarding responsibility.
- Enforce task-scoped authorization Bind each agent session to a narrowly defined task, data scope, and expiry window.
- Instrument full agent audit trails Log the user request, agent action, tool target, decision outcome, and downstream side effect in one traceable record.
That is why teams should evaluate MCP using runtime control concepts, not just integration checklists, and map their decisions to the NIST AI Risk Management Framework?

MCP identity orchestration creates an identity blast radius problem, not just an integration problem. Once an agent can talk to tools on its own behalf, the scope of possible damage is determined by the breadth of its access and the quality of its revocation path. Teams that treat MCP as a connector layer will miss the fact that connector design now shapes identity risk. Practitioners should govern the agent, not just the API.
A few things that frame the scale:
- 92% agree governing AI agents is critical to enterprise security, yet only 44% have implemented any policies to do so, according to AI Agents: The New Attack Surface report.
- Only 52% of companies can track and audit the data their AI agents access, leaving 48% with a complete blind spot for compliance and breach investigation.
A question worth separating out:
Q: Why do MCP-connected agents complicate zero trust architecture?
A: Zero trust assumes continuous verification, but MCP agents can complete multiple actions inside one trusted session. That creates a gap between initial verification and later behavior, so teams need runtime policy checks, telemetry, and revocation that follow the agent through every tool call.
