Delete a memory entity.
AI agents call forget to permanently remove resources in Oceanir Memory — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes data from the memory system and cannot be undone. Deleting memory entities could cause an AI agent to lose critical context, coding preferences, project patterns, or technical solutions that were previously stored.
From the tool's definition Tool name is 'forget' and description states 'Delete a memory entity.' The verb 'delete' combined with the context of persistent long-term memory storage indicates irreversible removal of stored data.
Attacks that exploit this kind of access
Delete a memory entity. It is categorised as a Destructive tool in the Oceanir Memory MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Oceanir Memory MCP server in PolicyLayer and add a rule for 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 Oceanir Memory. Nothing to install.
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 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 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.
forget is provided by the Oceanir Memory MCP server (oceanir/oceanir-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
