THE RISK

Medium Risk

Why sync_products needs a policy

This tool modifies existing product data in the database (price list updates across ~12,000 items). While not destructive (changes are reversible and data is not deleted), it clearly performs a Write operation by updating an external database.

From the tool's definition Tool description states it "Download latest Alko price list and update product database" and "Updates ~12,000 products". The word "update" and the scale of modification (12,000 products) indicate data modification.

POLICY

How to control sync_products

PolicyLayer is an MCP gateway — it sits between your AI agents and Alko MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for sync_products:

policy.json

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

sync_products 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.

Create a free account and register Alko MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
