AI agents call codex_delete_user to permanently remove resources in Sage MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
User deletion is an irreversible action that cannot be undone without administrative intervention to restore access. While not data deletion in the traditional sense, removing a user from an organization is a destructive operation that eliminates access rights and potentially associated resources.
From the tool's definition Tool name contains 'delete' and description states 'Remove a user from the organization' - this irreversibly deletes user account access and organizational membership.
Documented attack patterns abuse exactly the kind of access codex_delete_user gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sage MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for codex_delete_user:
{
"version": "1",
"default": "deny",
"hide": [
"codex_delete_user"
]
}codex_delete_user disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Remove a user from the organization. It is categorised as a Destructive tool in the Sage MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Sage MCP server in PolicyLayer and add a rule for codex_delete_user: 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 Sage MCP. Nothing to install.
codex_delete_user 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 codex_delete_user 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 codex_delete_user. 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.
codex_delete_user is provided by the Sage MCP server (sagemcp/sagemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
