WHAT IT DOES

What kill_process does on Desktop Commander MCP Server

AI agents call kill_process to permanently remove resources in Desktop Commander MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why kill_process is rated Critical

Killing a process is an irreversible action: any unsaved data in that process is lost, and critical system or application processes being killed can cause crashes or service outages. This matches the Destructive category due to its non-undoable nature and high blast radius if misused by an AI agent.

From the tool's definition "Terminate or kill a process by PID" — forcibly ends a running process, which is irreversible and may cause data loss or system instability.

RECOMMENDED RULE

The rule that runs kill_process safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Desktop Commander MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For kill_process, this is the rule to start with:

kill_process Hidden

kill_process is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
