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

```json
{
  "jsonrpc": "2.0",

## Why forget is rated Critical

The tool deletes data from persistent storage without the ability to recover it. While the severity is not critical (the blast radius is limited to a single user's notes rather than infrastructure or financial systems), the irreversible nature of deletion places it in the Destructive category, which ranks above Execute and Write.

From the tool's own definition: "'Permanently delete an entry' and 'This action cannot be undone' indicate irreversible deletion of data."

## Use case

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