Why common-update-item-referrer-by-id needs a policy

This tool modifies existing references/links in a Sitecore content management system by redirecting them to a new target or removing them entirely. While the changes are theoretically reversible (you could update references back or restore links), the blast radius is significant—updating all references to an item could break content relationships, page links, or dependencies throughout the system if misused.

From the tool's definition Tool description states it 'Updates all references to the specified item' and can 'remove links to the item'. The word 'Updates' indicates modification of data. The scope is broad ('all references'), affecting multiple data points across the system.

How to control common-update-item-referrer-by-id

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Sitecore, and nothing reaches the server without passing your rules. This is the rule we recommend for common-update-item-referrer-by-id:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "common-update-item-referrer-by-id": {
      "limits": [
        {
          "counter": "common-update-item-referrer-by-id_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

common-update-item-referrer-by-id 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 Sitecore — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
