Delete a memory and all its data.
AI agents call delete_memory to permanently remove resources in Structured-sh — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes data (a memory and all its associated data). Deletion operations that cannot be undone belong in the Destructive category. While the blast radius depends on what data is stored, the capability to permanently remove structured state across sessions represents a high-severity risk if misused by an AI agent—it could erase critical context, state, or historical information the agent or…
From the tool's definition delete_memory: Delete a memory and all its data.
Attacks that exploit this kind of access
Delete a memory and all its data. It is categorised as a Destructive tool in the Structured-sh MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Structured-sh 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 Structured-sh. 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 Structured-sh MCP server (structured-sh/structured). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
