SentinelX Overview

SentinelX runs an agent on each managed Linux or macOS host and exposes shell, filesystem, and service-management operations through MCP. Commands, services, and filesystem paths are restricted by configurable allowlists, and actions are recorded. Use it when an LLM needs controlled remote server administration without opening inbound ports.
