Soft-delete memories. Requires confirm=true to execute. Can target a specific ID or query-matched entries.
AI agents call memory.forget to permanently remove resources in Sovereign Universal Memory MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool deletes user memories from persistent storage, which cannot be undone even if technically marked as 'soft-delete'. An AI agent with access could maliciously or accidentally erase significant portions of a user's knowledge base by targeting either specific IDs or query-matched entries in bulk.
From the tool's definition Tool name 'memory.forget' combined with description 'Soft-delete memories' indicates irreversible deletion of stored data. The confirmation requirement (confirm=true) is a guard but does not change the destructive nature of the operation.

Register the Sovereign Universal Memory MCP server in PolicyLayer and add a rule for memory.forget: 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 Sovereign Universal Memory MCP. Nothing to install.
memory.forget 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 memory.forget 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 memory.forget. 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.
memory.forget is provided by the Sovereign Universal Memory MCP server (nnaveenraju/sovereign-universal-memory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
