WHAT IT DOES

What fs_restore_backup does on LocalAnt

AI agents use fs_restore_backup to create or update resources in LocalAnt, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your LocalAnt environment.

RISK

Why fs_restore_backup is rated Medium

Restoring a backup overwrites existing files and directories, constituting a reversible Write operation. It is not Destructive because backups typically preserve the old data (allowing rollback), and the operation can theoretically be undone by creating a new backup of the current state.

From the tool's definition Tool name 'fs_restore_backup' explicitly states it restores (applies) a previously created backup. The verb 'restore' indicates overwriting current files with backed-up versions, which modifies data on the filesystem.

RECOMMENDED RULE

The rule that runs fs_restore_backup safely

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

fs_restore_backup Rate-limited

fs_restore_backup stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
