Why update_main_menu_link needs a policy

This tool creates or modifies data reversibly by updating menu links. While it affects site navigation (potentially impacting customer experience), the changes are non-destructive and can be reverted. It does not delete data (which would be Destructive), execute arbitrary code (which would be Execute), or involve financial transactions.

From the tool's definition Tool name 'update_main_menu_link' and description 'Update a main menu navigation link' indicate modification of existing menu navigation data.

POLICY

How to control update_main_menu_link

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_main_menu_link:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "update_main_menu_link": {
      "limits": [
        {
          "counter": "update_main_menu_link_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

update_main_menu_link 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.
