RISK

Why update_product is rated Medium

This tool modifies product data within the CRM system but does not delete or irreversibly destroy information. The effect is reversible—updated fields can be changed again. It does not execute arbitrary code, trigger external operations with unpredictable effects, move money, or destroy data. It falls squarely into the Write category as a data modification operation.

From the tool's definition Tool name 'update_product' and description 'Update an existing product. Only provided fields are changed.' indicate modification of existing data in a reversible manner.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_product safely

PolicyLayer is an MCP gateway: it sits between your AI agents and FavCRM, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For update_product, this is the rule to start with:

update_product Rate-limited

update_product 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.

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

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect FavCRM, apply this rule, and every update_product call is checked against it from then on.
