WHAT IT DOES

What open_console_session does on Claude-Modeling-Labs MCP Server

AI agents invoke open_console_session to trigger actions in Claude-Modeling-Labs 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 open_console_session needs a policy

Opening a console session to a network node provides direct interactive access to that device, allowing execution of arbitrary commands on the device. This is analogous to opening a shell session — effects depend entirely on what commands are subsequently run. Misuse could lead to device misconfiguration, data exfiltration, or network disruption.

From the tool's definition 'Open a console session to a node in the lab' — opening a console session establishes an interactive terminal/shell connection to a network device
