We have taken to letting our agents use specific CLIs directly and we narrow down their access control with nono tool sandboxing via a customized Pi agent running headless. We have one agent that can use the aws CLI and nono feeds in a phantom SigV4 credential and then policy limits to just read-only http methods and certain L7 filtering on paths to limit its abilities - this means we can have it monitor and debug deployment failures without it doing any damage.

It was all largely based off this example https://github.com/nolabs-ai/nono/tree/main/tool-sandbox-exa...

How is this better than using MCP?
