What powershell does on Claude C2
AI agents invoke powershell to trigger actions in Claude C2. 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 powershell is rated High
PowerShell execution on remote Windows systems is inherently an Execute category tool, as it can run arbitrary code whose effects depend entirely on the command argument supplied by the AI agent.
From the tool's definition Tool name is 'powershell' and description states 'Execute PowerShell command on Windows client' — direct execution of arbitrary commands on a remote system.
Attacks that exploit this kind of access
The rule that runs powershell safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Claude C2, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For powershell, this is the rule to start with:
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.
The button opens the PolicyLayer dashboard: create your workspace, connect Claude C2, apply this rule, and every powershell call is checked against it from then on.

powershell is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the powershell rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
