TL;DR: MCP and Skills widen agent governance risk when teams stack tools, instructions, and identities into one runtime path, according to JetStream Security. That path can expand privilege, reach, and accountability beyond what separate reviews catch.
Editorial analysis by NHI Mgmt Group, based on content published by JetStream Security: “MCP vs. Skills: A False Debate”.
Key questions
Q: Why do stacked MCP and Skill workflows increase governance risk?
A: Because each added component expands either the agent’s reachable systems or the instruction surface that shapes its actions.
Q: How should teams govern AI agents that use tools during evaluation?
A: Treat the agent’s permissions as part of the test itself.
Q: What breaks when AI agents can chain tools through MCP without tight policy controls?
A: What breaks is the separation between request, authorisation, and execution.
Practitioner guidance
- Define the agent runtime contract Document which MCP servers, Skills, and identities are permitted for each workflow before it moves beyond pilot use.
- Separate tool approval from instruction approval Review MCP connectivity and Skill content as distinct governance decisions, because each changes risk in a different way.
- Scope destructive tools out of routine workflows Block actions such as delete, write, or submit unless the task explicitly needs them and the workflow owner can justify them.
Bottom line: MCP and Skills solve different problems, but the governance failure appears when teams treat them as competing substitutes instead of complementary controls.

Stacked AI workflows create a governance problem, not a product choice problem. The article is right that MCP and Skills are complementary, because the real issue is not which one wins but how the assembled workflow is governed. Once an agent can combine tools and instructions at runtime, the control boundary moves from component approval to orchestration control. Practitioners should stop evaluating these as substitutes and start governing them as one delegated execution chain.
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: What is the difference between agent skills and MCP?
A: Agent skills provide the procedure, meaning how an agent should do a task. MCP provides the connection to tools and data, meaning what the agent can reach. They work together, but they solve different problems. Skills govern behaviour, while MCP governs access to external capabilities and should be controlled separately.
