## Why forecast_models_cleanup is rated Critical

Although the tool includes a preview capability (reversible), its primary destructive function—permanently deleting stored forecast models without possibility of recovery—places it in the Destructive category. This is more severe than Write (which is reversible) because deletion operations are irreversible.

From the tool's own definition: "The tool performs 'delete' operations on stored forecast models, which are irreversibly removed. The description explicitly states the tool can 'delete stale stored forecast models,' meeting the definition of a destructive action that cannot be undone."

## Use case

AI agents call forecast_models_cleanup to permanently remove resources in MetaTrader5 MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)
