AI agents use update_category to create or update resources in PrestaShop MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your PrestaShop MCP Server environment.
This tool modifies category data within the PrestaShop e-commerce system. Updates are reversible (the category can be modified again), distinguishing this from destructive operations. The blast radius is medium because incorrect category updates could affect product visibility, pricing, or navigation, but changes can be undone.
From the tool's definition Tool name is 'update_category' and description states 'Update an existing category', indicating modification of existing data in a reversible manner.
Documented attack patterns abuse exactly the kind of access update_category 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_category:
{
"version": "1",
"default": "deny",
"tools": {
"update_category": {
"limits": [
{
"counter": "update_category_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_category stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Update an existing category. It is categorised as a Write tool in the PrestaShop MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the PrestaShop MCP Server MCP server in PolicyLayer and add a rule for update_category: 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_category is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update_category 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_category. 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_category 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.
