Soft-delete a memory item. Use for incorrect or sensitive data.
AI agents call memory_forget to permanently remove resources in Codemem — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly removes or disables access to stored data (memory items) in a persistent memory system. Although labeled 'soft-delete,' the functional outcome is deletion of information that cannot be recovered through normal means. In the context of an AI coding session, deleting memories could erase important context, decisions, or learning.
From the tool's definition Tool name is 'memory_forget' with description 'Soft-delete a memory item.' The operation removes stored memory records from persistent storage, which is irreversible in terms of data retrieval even if technically a 'soft-delete' that marks records rather than…
Documented attack patterns abuse exactly the kind of access memory_forget gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Codemem, and nothing reaches the server without passing your rules. This is the rule we recommend for memory_forget:
{
"version": "1",
"default": "deny",
"hide": [
"memory_forget"
]
}memory_forget disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Soft-delete a memory item. Use for incorrect or sensitive data. It is categorised as a Destructive tool in the Codemem MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Codemem MCP server in PolicyLayer and add a rule for memory_forget: 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 Codemem. Nothing to install.
memory_forget 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_forget 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_forget. 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_forget is provided by the Codemem MCP server (kunickiaj/codemem). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Codemem, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
