Why update_category needs a policy

This tool modifies a product category attribute reversibly. There is no indication of deletion, financial transaction, code execution, or destructive action. The operation is a straightforward data modification (Write). Severity is low because category updates are non-critical metadata changes with minimal business impact and easily reversible.

From the tool's definition Tool name 'update_category' and description 'Update a product category' indicate a modification operation on product data.

POLICY

How to control update_category

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for update_category:

policy.json

{
  "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.

Create a free account and register Mcp Ap2 — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
