Delete a specific memory by ID
AI agents call delete_memory to permanently remove resources in MCP MITM Mem0 — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool directly deletes data without reversibility, which is the defining characteristic of the Destructive category. While the blast radius is limited to conversation memories rather than production data, unauthorized deletion of conversation history and user preferences could disrupt context continuity and learning across sessions, causing user harm.
From the tool's definition Tool name 'delete_memory' with description 'Delete a specific memory by ID' performs irreversible deletion of stored data. The action cannot be undone and removes information permanently from the Mem0 storage system.
Attacks that exploit this kind of access
Delete a specific memory by ID. It is categorised as a Destructive tool in the MCP MITM Mem0 MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MCP MITM Mem0 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 MCP MITM Mem0. 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 MCP MITM Mem0 MCP server (terrymunro/mcp-mitm-mem0). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
