Runs a PowerShell script and returns the output.
AI agents invoke run-powershell-script to trigger actions in Mcp Sitecore. 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.
This tool executes arbitrary PowerShell scripts, which can perform any operation the Sitecore server process permits: reading/writing/deleting files, modifying system state, executing shell commands, accessing databases, or triggering external operations. PowerShell script execution is inherently Execute-class behavior.
From the tool's definition Runs a PowerShell script and returns the output.
Documented attack patterns abuse exactly the kind of access run-powershell-script gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Sitecore, and nothing reaches the server without passing your rules. This is the rule we recommend for run-powershell-script:
{
"version": "1",
"default": "deny",
"tools": {
"run-powershell-script": {
"limits": [
{
"counter": "run-powershell-script_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}run-powershell-script 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.

Runs a PowerShell script and returns the output. It is categorised as a Execute tool in the Mcp Sitecore MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Mcp Sitecore MCP server in PolicyLayer and add a rule for run-powershell-script: 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 Mcp Sitecore. Nothing to install.
run-powershell-script 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-script 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-script. 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.
run-powershell-script is provided by the Mcp Sitecore MCP server (@antonytm/mcp-sitecore-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcp Sitecore, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
