AI agents call memory_delete to permanently remove resources in Wasurenagusa — 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 persistent memory storage. Deletion is an irreversible operation with no undo capability. The ability to batch-delete across categories increases the blast radius. An AI agent with unrestricted access could accidentally or maliciously wipe project rules, decisions, and configurations critical to the assistant's operation.
From the tool's definition Tool name 'memory_delete' combined with description stating it 'deletes memory entries' (メモリエントリを削除する) with ability to delete multiple IDs at once (複数IDを一括指定可能) and across categories (カテゴリをまたいだ削除もOK). The action is explicitly irreversible deletion.

Register the Wasurenagusa MCP server in PolicyLayer and add a rule for memory_delete: 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 Wasurenagusa. Nothing to install.
memory_delete 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_delete 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_delete. 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_delete is provided by the Wasurenagusa MCP server (tsutushi0628/wasurenagusa-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
