Exploring AI Agent Limitations: How Much Control Do We Have?

Lately, I've been diving into the world of AI agent platforms, and what's fascinating is how they allow us to set boundaries on what these agents can access. I'm curious about how much control we truly have over these agents, especially when it comes to their ability to read and act on different data sources. How do we ensure that the AI doesn't exceed its intended scope, and what measures can we put in place to prevent unauthorized access to sensitive info? Has anyone here experimented with setting strict access permissions, and what challenges have you faced in maintaining those boundaries?
