It's not about enforcing read-only - we want agents to do destructive things. Like rebooting a pod, rolling back a deployment, etc.
Plus a lot of these services are reached by tunneling through something else. We tunnel into k8s where it has dangerous credentials.
We also don't want to define MCPs for everything. The principle is that the agent doesn't need code changes, including skills/MCPs - it just accesses systems.
Claw Patrol lets us give agents more access because it's watching everything at the wire. `kubectl delete pod foo` waits for slack approval, SELECT on env_vars runs through an LLM judge to check if it actually returns secret data. For our setup this is security policy that is a single file, checked into git, that gates access across 14 k8s clusters, clickhouse, postgres, a dozen other HTTP APIs.
