Don’t Hand Your AI Agent the Keys: MCP vs. Context Layers
AI-enabling your systems is easy if you believe the brochures in your inbox. Wrap the system you already have in an MCP server, point a model at it, done. By the end of the day, you can ask your CRM questions in plain English and watch it update records.

The article warns against using AI agents with unrestricted access to systems. While connecting AI agents to tools and data through an MCP (Model-Content-Platform) protocol is convenient, it doesn't ensure security. Exposing production systems without independent authorization controls can give compromised AI agents dangerous access. The model shouldn't hold the keys.
Context layers are introduced to enforce permissions and restrict available actions, protecting backend systems. They don't rely on AI-generated decisions. For production AI, security measures should include controlled data access, task-specific capabilities, observability, and auditable operations.
Wrapping an existing system in an MCP server and pointing a model at it can give the impression that AI has been enabled, but this approach doesn't address the underlying security concerns. If a model is given instructions that could compromise data, it may follow those instructions regardless of guardrails. The fix is to invert responsibilities: the system stays in control, while the model only receives input and a list of specific actions to perform.
A context layer should pull relevant data from existing systems, keep it in sync, and provide the model with a connected view. This approach ensures security, availability, observability, and maintainability.
