Removes a base template from a template item by its path.
AI agents use common-remove-base-template-by-path 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.
Removing a base template modifies the template's inheritance structure in Sitecore, which is a significant write operation. While potentially reversible (you could re-add the base template), it can have wide-reaching effects on all items based on that template, breaking field inheritance and rendering. This warrants a high severity rating due to the blast radius.

Documented attack patterns abuse exactly the kind of access common-remove-base-template-by-path 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-remove-base-template-by-path:
{
"version": "1",
"default": "deny",
"tools": {
"common-remove-base-template-by-path": {
"limits": [
{
"counter": "common-remove-base-template-by-path_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
} common-remove-base-template-by-path 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.

Removes a base template from a template item by its path. 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-remove-base-template-by-path: 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-remove-base-template-by-path 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-remove-base-template-by-path 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-remove-base-template-by-path. 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-remove-base-template-by-path 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.
