AI agents call widemem_delete to permanently remove resources in Widemem Ai — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a memory record is an irreversible operation that cannot be undone. Once a memory is deleted by ID, it is removed from the system's SQLite + FAISS backend. An AI agent with misuse of this tool could selectively erase important facts, summaries, or historical context from the memory layer, degrading the integrity of the agent's knowledge base and potentially causing loss of critical information.
From the tool's definition Tool name is 'widemem_delete' and description explicitly states 'Delete a memory by its ID.' The verb 'delete' is a canonical destructive action that irreversibly removes data.
Documented attack patterns abuse exactly the kind of access widemem_delete gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Widemem Ai, and nothing reaches the server without passing your rules. This is the rule we recommend for widemem_delete:
{
"version": "1",
"default": "deny",
"hide": [
"widemem_delete"
]
}widemem_delete disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete a memory by its ID. It is categorised as a Destructive tool in the Widemem Ai MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Widemem Ai MCP server in PolicyLayer and add a rule for widemem_delete: 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 Widemem Ai. Nothing to install.
widemem_delete 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 widemem_delete 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 widemem_delete. 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.
widemem_delete is provided by the Widemem Ai MCP server (remete618/widemem-ai). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
