Converts an item from a clone to a fully independent item by its ID.
AI agents use common-convert-from-item-clone-by-id to create or update resources in Mcp Sitecore — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Sitecore environment.
The tool modifies data (item cloning relationships) within Sitecore. While not creating new items outright, it transforms an existing item's dependency structure, which is a Write-category operation (reversible data modification). Severity is high because incorrect use could break content inheritance chains or create unintended independent copies in a critical CMS, affecting content management workflows.
From the tool's definition Tool description states it "Converts an item from a clone to a fully independent item by its ID." This is a modification operation that changes the structure/state of an item in Sitecore by converting a clone relationship, which is a reversible structural…
Documented attack patterns abuse exactly the kind of access common-convert-from-item-clone-by-id gives an agent:
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-convert-from-item-clone-by-id:
{
"version": "1",
"default": "deny",
"tools": {
"common-convert-from-item-clone-by-id": {
"limits": [
{
"counter": "common-convert-from-item-clone-by-id_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
} common-convert-from-item-clone-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.

Converts an item from a clone to a fully independent item by its ID. It is categorised as a Write tool in the Mcp Sitecore MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mcp Sitecore MCP server in PolicyLayer and add a rule for common-convert-from-item-clone-by-id: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp Sitecore. Nothing to install.
common-convert-from-item-clone-by-id is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the common-convert-from-item-clone-by-id rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for common-convert-from-item-clone-by-id. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
common-convert-from-item-clone-by-id is provided by the Mcp Sitecore MCP server (@antonytm/mcp-sitecore-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcp Sitecore, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
