Delete memory entries matching filters. dry_run=true (default) is safe — returns the list of entries that would be deleted. Pinned entries are never forgotten. At least one filter required. Owner only — registered handle + secret required.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "forget_memories",
    "arguments": {
      "handle": "<handle>"
    }
  }
}
```

## Why forget_memories is rated Critical

This tool permanently deletes memory entries, which cannot be undone. While dry_run=true provides a safeguard to preview deletions, the actual operation (dry_run=false or default behavior) irreversibly removes data. The ownership requirement and authentication (registered handle + secret) mitigate risk somewhat, but misuse by an authenticated agent could still cause unrecoverable data loss.

From the tool's own definition: "Tool name is 'forget_memories' and description explicitly states 'Delete memory entries matching filters.' The destructive nature is confirmed by the phrase 'returns the list of entries that would be deleted' and the note that 'Pinned entries are never…"

Risk signals: Handles credentials or secrets (secret)

## Use case

AI agents call forget_memories to permanently remove resources in Gateway, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Gateway:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "forget_memories"
  ]
}
```
