Clear all stored memories. Use with caution as this cannot be undone.
AI agents call clear_memories to permanently remove resources in AI Memory MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently deletes all stored memories without recovery options. The phrase "cannot be undone" explicitly confirms irreversibility. Even though the blast radius is limited to the user's memory store (not system-wide), the complete and permanent loss of all conversational context and stored data represents a critical destructive action.
From the tool's definition "Clear all stored memories" and "Use with caution as this cannot be undone" directly indicate irreversible deletion of all data.

Clear all stored memories. Use with caution as this cannot be undone. It is categorised as a Destructive tool in the AI Memory MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the AI Memory MCP Server MCP server in PolicyLayer and add a rule for clear_memories: 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 AI Memory MCP Server. Nothing to install.
clear_memories 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 clear_memories 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 clear_memories. 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.
clear_memories is provided by the AI Memory MCP Server MCP server (scofieldkoh/mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
