AI agents may call delete_memory to permanently remove or destroy resources in Mem0 Memory Server. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. PolicyLayer blocks destructive tools by default and requires explicit human approval before enabling them.

Without a policy, an AI agent could call delete_memory in a loop, permanently destroying resources in Mem0 Memory Server. There is no undo for destructive operations. PolicyLayer blocks this tool by default and only allows it when a human explicitly approves the action.

Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so delete_memory only ever does what you allow.

What does the delete_memory tool do? +

Deletes a specific memory by ID from Mem0.. It is categorised as a Destructive tool in the Mem0 Memory Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on delete_memory? +

Register the Mem0 Memory Server 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 Mem0 Memory Server. Nothing to install.

What risk level is delete_memory? +

delete_memory is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit delete_memory? +

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.

How do I block delete_memory completely? +

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.

What MCP server provides delete_memory? +

delete_memory is provided by the Mem0 Memory Server MCP server (pinkpixel-dev/mem0-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Mem0 Memory Server tool call.
