WHAT IT DOES

What run_powershell does on Allcanuse

AI agents invoke run_powershell to trigger actions in Allcanuse. 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.

RISK

Why run_powershell is rated High

PowerShell execution is inherently an Execute category tool—it runs code whose effects entirely depend on the arguments passed. With no constraints evident, an AI agent could execute any PowerShell command (malware installation, data exfiltration, system compromise, lateral movement). The blast radius is critical: full system compromise is possible.

From the tool's definition Tool name 'run_powershell' indicates execution of PowerShell commands. Server description mentions 'command execution' as a core capability. PowerShell is a full-featured shell enabling arbitrary system operations.

RECOMMENDED RULE

The rule that runs run_powershell safely

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

run_powershell Rate-limited

run_powershell stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

        }

    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Allcanuse, apply this rule, and every run_powershell call is checked against it from then on.
