Surgically delete a memory by node_id. Audit log preserved.
AI agents call forget to permanently remove resources in Recall — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The forget tool performs irreversible deletion of memory records. Although an audit trail is maintained, the underlying data is permanently removed and cannot be restored, making this a destructive operation.
From the tool's definition 'Surgically delete a memory by node_id' — the tool irreversibly removes data entries from the memory graph, though the audit log is preserved for accountability.
Attacks that exploit this kind of access
Surgically delete a memory by node_id. Audit log preserved. It is categorised as a Destructive tool in the Recall MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Recall 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 Recall. 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 Recall MCP server (yash194/recall). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
