TL;DR: MCP standardizes how LLMs call tools and services, but Strata Identity argues that missing user context, weak auditability, and untrusted tool sources turn that convenience into a wider attack surface, especially when approvals and policy enforcement are absent. Identity-aware policy checks are the deciding control, not the protocol itself.
Editorial analysis by NHI Mgmt Group, based on content published by Strata Identity: “What is Model Context Protocol (MCP) security?”.
Key questions
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.
Q: Why do unchecked MCP tool calls create more risk than ordinary automation?
A: Unchecked MCP calls are riskier because they let a model initiate actions with real-world side effects without the same identity checks that govern human or service access.
Q: What breaks when MCP tool registries are not controlled?
A: When registries are not controlled, malicious or poisoned tool definitions can enter the workflow as if they were legitimate.
Practitioner guidance
- Bind tool calls to verified identity context Require each MCP request to carry the user identity, roles, groups, entitlements, and risk signals that determine whether the action is allowed.
- Enforce runtime policy checks before execution Evaluate each tool invocation against dynamic policy at the point of use, not only at registration or configuration time.
- Curate MCP registries and reject unvetted tools Limit tool discovery to known-good definitions that are mapped to governance rules and approval requirements.
Bottom line: MCP extends model utility, but the article shows that utility becomes a security issue when identity context is missing from tool decisions.

MCP creates an identity context gap, not just a new integration layer: The article shows that the real failure mode is not tool access itself but the loss of user context when models act through MCP. That context gap breaks the normal IAM logic that ties action to a known subject, known authority, and known risk. The practitioner implication is that MCP security has to be assessed as an identity problem before it is treated as an AI tooling problem.
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.
- AI-related credential leaks surged 81.5% year-over-year in 2025, with the surrounding AI infrastructure leaking 5x faster than core LLM providers, according to the State of Secrets Sprawl 2026.
A question worth separating out:
Q: How do approval gates change MCP governance for high-risk actions?
A: Approval gates stop sensitive actions from becoming model-only decisions. They preserve human accountability for requests that can alter permissions, move money, or touch sensitive systems, while still allowing lower-risk tool use to proceed under policy. That separation is essential when a model can act faster than a human reviewer can react.
