RECOMMENDED RULE

The rule that runs libi.restore_snapshot safely

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

libi.restore_snapshot Hidden

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