WHAT IT DOES

What system_clear_cache does on Aapanel

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

RISK

Why system_clear_cache is rated Critical

Clearing system cache is an irreversible operation that permanently removes cached data from memory. While it doesn't delete persistent data, the cache cannot be recovered once cleared, making it a destructive action. Misuse could cause performance degradation or disrupt running services that rely on cached data.

RECOMMENDED RULE

The rule that runs system_clear_cache safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Aapanel, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For system_clear_cache, this is the rule to start with:

system_clear_cache Hidden

system_clear_cache is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
