The Model Context Protocol (MCP) debate has been heating up throughout 2026, and a piece in The New Stack — published today and sponsored by GitLab — makes the enterprise governance case loud and clear. The argument is straightforward: critics who dismiss MCP as overly complex are misunderstanding what enterprise-scale AI agents actually require.

Transparency note: This article is a GitLab-sponsored piece in The New Stack, written by Amanda Rueda. We’re covering it because the governance and security framing is genuine and relevant — but the editorial perspective is aligned with a vendor actively building MCP tooling. We note this so you can weigh the framing accordingly.

The “Context Problem” Framing

The article positions what it calls a “context problem” at the heart of MCP skepticism. Detractors argue that MCP adds complexity — more configuration, more infrastructure, more things to go wrong — without proportional benefit. But the counterargument is that this criticism confuses configuration overhead with architectural necessity.

For single-agent, single-task AI systems, MCP might indeed be overkill. But enterprise deployments don’t look like that. They involve:

  • Multiple agents with different permissions and access levels
  • Tools that touch production systems (databases, email, customer records)
  • Audit requirements driven by compliance, security, and enterprise IT governance
  • Complex context chains where one agent’s output becomes another’s input

Without a structured protocol for context management, these systems don’t scale — they sprawl. The “context problem” isn’t that MCP creates complexity; it’s that unstructured agent deployments are complex by default, just invisibly so.

Why Context Governance Matters at Scale

The piece makes a compelling point about what happens when enterprise agents lack structured context management:

Security boundaries blur. When agents share context without explicit access controls, a customer-facing support agent can inadvertently access internal financial data if context propagation isn’t governed. MCP’s structured permission model enforces boundaries at the protocol level.

Audit trails disappear. Enterprise IT and legal teams need to know what context an agent had when it took a consequential action. Who approved the expense? What data did the agent see when it recommended the inventory change? Without structured context, these questions become expensive forensics exercises.

Context quality degrades at scale. As agent pipelines grow, unstructured context accumulates. MCP introduces discipline around what gets passed, in what format, and with what lifecycle — reducing the context bloat and hallucination risk that plagues large unstructured agent chains.

Governance becomes a patchwork. Without a protocol, each tool, each agent, and each integration team invents its own context-passing convention. The result is a governance nightmare that grows harder to manage with each new agent deployment.

The MCP Governance Stack

The article outlines what MCP-enabled enterprise governance actually looks like in practice:

  • Structured tool invocations: Every tool call goes through MCP’s typed interface, creating a machine-readable record of what was requested, what parameters were passed, and what was returned.
  • Permission scoping: Agents request capabilities explicitly, and administrators can audit and revoke access at a protocol level.
  • Context provenance: The chain of context that led to a decision can be traced — useful for debugging agent misbehavior and for compliance reporting.
  • Interoperability: MCP’s open protocol means that governance tooling built once works across different agent frameworks, reducing vendor lock-in at the governance layer.

GitLab’s interest here is transparent: they’re investing in MCP tooling as part of their DevSecOps platform, and an MCP-governed AI agent ecosystem is a natural extension of their existing security and audit toolchain. The argument isn’t wrong because it’s commercially motivated — it happens to be technically sound as well.

The Counter-View Worth Taking Seriously

What the article doesn’t engage with deeply is the real criticism that enterprise MCP adoption faces: context window cost.

Every layer of structured context passed through MCP carries token overhead. For high-throughput enterprise workloads, structured protocol overhead isn’t zero. Teams building latency-sensitive or cost-sensitive agentic applications need to model the token cost of governance, not just its security benefits.

The governance-versus-efficiency tension is real, and an honest assessment of MCP adoption needs to address it directly. The best enterprise implementations of MCP will be those that make governance selectively expensive — enforcing it where it matters (high-risk tool calls, cross-boundary context propagation) and keeping it lightweight where it doesn’t.

What This Means for Your Agent Stack

If you’re evaluating MCP for enterprise deployment, the governance argument is the right starting point. The question isn’t “do we need MCP?” for most enterprise teams — it’s “what governance gaps does our current approach have, and what would it cost to remediate them without a protocol?”

The answer usually makes MCP look practical.

MCP adoption statistics from a separate report this week suggest 41% of organizations using MCP have it in limited or broad production deployment. The enterprise case has clearly passed the “early adopter” phase.

The context problem is real. The question is whether you address it with a protocol — or discover it the hard way in production.
