WHAT IT DOES

What delete_work_memory does on Work Memory MCP Server

AI agents call delete_work_memory to permanently remove resources in Work Memory MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

THE RISK

Critical Risk

Why delete_work_memory needs a policy

This tool irreversibly deletes persistent data across multiple categories (work memories, sessions, history, indexes). The capability to perform wholesale deletion ('전체 삭제') on structured work content and context cannot be undone. While the blast radius is limited to work memory data rather than critical systems, the irreversible nature and potential to wipe entire project contexts justifies the Destructive category.

From the tool's definition delete_work_memory is explicitly a deletion tool that supports 'category-specific segmented deletion' of work memories, sessions, history, and search indexes.

POLICY

How to control delete_work_memory

PolicyLayer is an MCP gateway — it sits between your AI agents and Work Memory MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_work_memory:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_work_memory"
  ]
}

delete_work_memory disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
