What run_powershell does on Mapi Agent Memory
AI agents invoke run_powershell to trigger actions in Mapi Agent Memory. 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 run_powershell is rated High
Running PowerShell scripts permits execution of arbitrary code whose effects depend on the script arguments and content. This is a classic Execute pattern. Severity is critical because PowerShell has broad system access and can perform destructive, financial, or other high-impact operations depending on the script.
From the tool's definition Tool description states "Run a PowerShell script", which directly invokes arbitrary code execution on the system. PowerShell is a command-line shell capable of executing operating system commands, scripts, and administrative operations.
Attacks that exploit this kind of access
The rule that runs run_powershell safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mapi Agent Memory, 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 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 Mapi Agent Memory, apply this rule, and every run_powershell call is checked against it from then on.
Questions about run_powershell

Register the Mapi Agent Memory MCP server in PolicyLayer and add a rule for run_powershell: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mapi Agent Memory. Nothing to install.
run_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 run_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.
Set action: deny in the PolicyLayer policy for run_powershell. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
