pikvm_type · PiKVM MCP Server MCP: Risk & Policy

WHAT IT DOES

What pikvm_type does on PiKVM MCP Server

AI agents invoke pikvm_type to trigger actions in PiKVM 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 pikvm_type needs a policy

Typing text on a remote machine is an Execute-level action because the effects are entirely dependent on the arguments: typed text could run shell commands, enter credentials, interact with applications, or cause destructive operations. Combined with the server's stated purpose of 'full keyboard, mouse, and screen control of a physical machine,' misuse could have severe consequences on the remote system.

From the tool's definition 'Type text on the remote machine using PiKVM' — sends keyboard input to a physical machine, triggering arbitrary actions depending on what text is typed (commands, passwords, scripts, etc.)
