AI agents invoke update_module_status to trigger actions in PrestaShop MCP Server. 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.
Enabling or disabling a module triggers an operational state change in the e-commerce platform, which is an external operation with potentially significant side effects (e.g., breaking payment processing, disabling security modules, or disrupting store functionality). This is an Execute-category action since it triggers external operations whose effects depend on arguments.

Documented attack patterns abuse exactly the kind of access update_module_status gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and PrestaShop MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for update_module_status:
{
"version": "1",
"default": "deny",
"tools": {
"update_module_status": {
"limits": [
{
"counter": "update_module_status_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}update_module_status 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.

Activate or deactivate a module. It is categorised as a Execute tool in the PrestaShop MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the PrestaShop MCP Server MCP server in PolicyLayer and add a rule for update_module_status: 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 PrestaShop MCP Server. Nothing to install.
update_module_status 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 update_module_status 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 update_module_status. 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.
update_module_status is provided by the PrestaShop MCP Server MCP server (latinogino/prestashop-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from PrestaShop MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
