forget|delete|remove|erase - Delete specific memory
AI agents call delete_memory to permanently remove resources in Hi-AI — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
An AI agent that decides to call delete_memory doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from Hi-AI is gone — there is no undo for destructive operations.
Attacks that exploit this kind of access
forget|delete|remove|erase - Delete specific memory. It is categorised as a Destructive tool in the Hi-AI MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Hi-AI MCP server in PolicyLayer and add a rule for delete_memory: 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 Hi-AI. Nothing to install.
delete_memory 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 delete_memory 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 delete_memory. 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.
delete_memory is provided by the Hi-AI MCP server (ssdeanx/ssd-ai). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
