pause_kasm_session · Kasm MCP Server v2 MCP: Risk & Policy

WHAT IT DOES

What pause_kasm_session does on Kasm MCP Server v2

AI agents invoke pause_kasm_session to trigger actions in Kasm MCP Server v2. 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 pause_kasm_session needs a policy

Pausing a session triggers an external operational state change on a containerized desktop session. It is not a simple read, nor does it irreversibly delete data. The session is suspended (not destroyed), making it reversible and thus not Destructive. It executes an action against live infrastructure, fitting the Execute category. Misuse could disrupt active user sessions, warranting medium severity.
