Why security-set-item-acl-by-id needs a policy

This tool modifies ACL (access control list) entries on Sitecore items by ID. While ACL changes are theoretically reversible (can be undone), they directly alter security permissions and could grant unauthorized access, lock out legitimate users, or escalate privileges. This is a Write operation with high severity because misconfiguration could compromise system security and have broad organizational impact.

From the tool's definition 'Sets an access control entry to a Sitecore item' – modifies security permissions on an item, which is a reversible but consequential data modification that affects access control.

POLICY

How to control security-set-item-acl-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 security-set-item-acl-by-id:

policy.json

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

security-set-item-acl-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.
