Clears all access rules from a Sitecore item by its ID.
AI agents call security-clear-item-acl-by-id to permanently remove resources in SitecoreMCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Clearing all ACL (Access Control List) rules from an item is an irreversible destructive action that removes all security permissions. This could expose previously protected content to unauthorized access or lock out legitimate users, with potentially wide blast radius across the entire security model for that item and its descendants.

Attacks that exploit this kind of access
Clears all access rules from a Sitecore item by its ID. It is categorised as a Destructive tool in the SitecoreMCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Sitecore MCP server in PolicyLayer and add a rule for security-clear-item-acl-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 SitecoreMCP. Nothing to install.
security-clear-item-acl-by-id is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the security-clear-item-acl-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 security-clear-item-acl-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.
security-clear-item-acl-by-id is provided by the Sitecore MCP server (ramseur/mcp-sitecore-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
