WHAT IT DOES

What clear_project_index does on ACE-MCP

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

RISK

Why clear_project_index is rated Critical

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

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs clear_project_index safely

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

clear_project_index Hidden

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