Delete one or more memories with full security gating (RBAC + AAL + audit).
AI agents call memory_delete_secure to permanently remove resources in Celiums Memory — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly removes data (memories) from the system. While it includes security controls (RBAC, AAL, audit), these are mitigations rather than reclassifications. The core function is destructive deletion, placing it in the Destructive category rather than Write.
From the tool's definition Tool name contains 'delete' and description states 'Delete one or more memories' - explicit destructive action. Deletion of memories is irreversible and cannot be undone.
Documented attack patterns abuse exactly the kind of access memory_delete_secure gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Celiums Memory, and nothing reaches the server without passing your rules. This is the rule we recommend for memory_delete_secure:
{
"version": "1",
"default": "deny",
"hide": [
"memory_delete_secure"
]
}memory_delete_secure disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete one or more memories with full security gating (RBAC + AAL + audit). It is categorised as a Destructive tool in the Celiums Memory MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Celiums Memory MCP server in PolicyLayer and add a rule for memory_delete_secure: 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 Celiums Memory. Nothing to install.
memory_delete_secure 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 memory_delete_secure 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 memory_delete_secure. 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.
memory_delete_secure is provided by the Celiums Memory MCP server (terrizoaguimor/celiums-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Celiums Memory, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
