Clear local cache for multiple browser profiles at once
AI agents call delete-cache-batch to permanently remove resources in TgeBrowser MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes cache data without a reversible operation. While cache deletion is often recoverable through system backups, the tool itself provides no undo mechanism and the batch operation amplifies the blast radius by affecting multiple profiles at once. This qualifies as Destructive rather than Write due to its irreversible nature.
From the tool's definition Tool name 'delete-cache-batch' and description 'Clear local cache for multiple browser profiles at once' indicate irreversible deletion of cached data across multiple profiles simultaneously.
