memory_batch_delete

THE RISK

Critical Risk

This tool permanently removes multiple memory records in bulk without apparent recovery mechanism. The irreversible nature of deletion combined with the batch/bulk operation scope (affecting many records simultaneously) makes this a Destructive action.

From the tool's definition Tool name includes 'delete' and description explicitly states 'BATCH DELETE BULK REMOVE - Delete multiple memories at once' with keywords 'batch delete, bulk remove, mass delete, delete many, remove all, clear multiple'.

HOW TO CONTROL MEMORY_BATCH_DELETE

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

policy.json

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

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

Create a free account and register MCP AI Memory — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
