GDPR right to be forgotten: erase all memories containing a PII identifier. Replaces content with [REDACTED], preserves anonymized audit trail. IRREVERSIBLE.
AI agents call memory_gdpr_erase to permanently remove resources in Mementos — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool performs irreversible data destruction across potentially many records (all memories containing a PII identifier). While the operation is legally mandated and preserves an audit trail, the permanent erasure of data qualifies as Destructive.
From the tool's definition Tool description explicitly states 'GDPR right to be forgotten: erase all memories containing a PII identifier' and 'IRREVERSIBLE'. The operation irreversibly replaces content with [REDACTED], permanently destroying original data.

GDPR right to be forgotten: erase all memories containing a PII identifier. Replaces content with [REDACTED], preserves anonymized audit trail. IRREVERSIBLE. It is categorised as a Destructive tool in the Mementos MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mementos MCP server in PolicyLayer and add a rule for memory_gdpr_erase: 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 Mementos. Nothing to install.
memory_gdpr_erase 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_gdpr_erase 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_gdpr_erase. 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.
