TL;DR: Model Context Protocol shifts security from static API transactions to agent-driven workflows where context, identity, privilege, and supply chain risks can cascade across tools and services, according to Aembit. Traditional gateway-centric controls were not built for dynamic agent behavior, so identity-first and runtime policy become the real control plane.
Editorial analysis by NHI Mgmt Group, based on content published by Aembit: “The Ultimate Guide to MCP Security Vulnerabilities”.
Key questions
Q: What breaks when MCP servers depend on static API keys or PATs?
A: Static credentials break the assumption that access can be tightly scoped, short-lived, and cleanly revoked.
Q: Why do MCP workflows increase the impact of a single credential or tool compromise?
A: Because MCP chains together agent decisions, context handoffs and downstream tool calls, one compromised identity can influence many later actions.
Q: How should security teams detect when context integrity is failing in MCP?
A: Look for mismatches between the expected source, structure and purpose of context and the action an agent takes with it.
Practitioner guidance
- Define workflow-scoped identity policy Bind each agent, tool and MCP server to runtime identity claims, then authorize only the exact step and resource needed for that interaction.
- Replace long-lived secrets with short-lived access Reduce static API keys and reusable tokens wherever possible, and reserve injected credentials for legacy systems that cannot authenticate natively.
- Validate context before downstream use Check source, structure and expected content of context at each boundary so poisoned or redirected inputs do not drive later tool calls.
Bottom line: MCP security fails when teams apply static API assumptions to agent-driven workflows with shifting context and chained tool use.

MCP creates an identity blast radius, not just an API exposure surface: the important control boundary is no longer the request, but the sequence of agent decisions, tool calls and context handoffs that follows. That means a failure in authentication, authorization or context trust can propagate across several services before any human notices. Practitioners should treat each workflow as a chain of delegated trust that must be governed end to end.
A few things that frame the scale:
- 67% of organisations still rely heavily on static credentials despite the risks they pose to agentic AI deployments, according to the 2026 Infrastructure Identity Survey.
- Half of companies using generative AI will deploy agentic AI by 2027, according to Deloitte's 2025 Technology Predictions.
A question worth separating out:
Q: How should security teams govern MCP gateway identity controls?
A: Treat the gateway as a relay point, not the place where every identity decision lives. Authentication, authorization, secrets custody, and audit logging should each have a clear owner and boundary. That separation reduces coupling, limits blast radius, and makes MCP governance easier to change without rewriting the proxy layer.
