WHAT IT DOES

What purge_caches does on Ae

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

Parameter	Type	Required	Description
`target`	string	—	all, memory, or disk. Defaults to all.
`timeoutMs`	number	—
`projectPath`	string	—

Parameters from the server's own tool schema.

RISK

Why purge_caches is rated Critical

An AI agent that decides to call purge_caches doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from Ae is gone. There is no undo for destructive operations.

RECOMMENDED RULE

The rule that runs purge_caches safely

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

purge_caches Hidden

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