WHAT IT DOES

What postdevicescommands does on Revel Digital MCP Server

AI agents invoke postdevicescommands to trigger actions in Revel Digital MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why postdevicescommands needs a policy

This tool triggers external operations on real hardware devices by sending commands. The effects depend entirely on what commands are sent (e.g., reboot, update, display change), making this an Execute-category tool. Misuse could affect multiple devices simultaneously, giving it a high severity blast radius.

From the tool's definition 'Sends a collection of commands to devices' — dispatches operational commands to physical digital signage devices
