Restore a world from a backup. Creates a safety backup of the current world before overwriting. The server MUST be stopped first.
AI agents call restore_backup to permanently remove resources in Minecraft Server MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Restoring a backup overwrites the current world entirely. Even though a safety backup is attempted first, the operation destroys the current world state and replaces it with an older snapshot — this is effectively irreversible in practice (especially if the safety backup fails or is later deleted).
From the tool's definition 'Restore a world from a backup... before overwriting' — the current world state is irreversibly overwritten; while a safety backup is created, the active world data is destroyed and replaced, which is a non-reversible destructive operation on live game state.
Attacks that exploit this kind of access
Restore a world from a backup. Creates a safety backup of the current world before overwriting. The server MUST be stopped first. It is categorised as a Destructive tool in the Minecraft Server MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Minecraft Server MCP server in PolicyLayer and add a rule for restore_backup: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Minecraft Server MCP. Nothing to install.
restore_backup is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the restore_backup rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for restore_backup. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
restore_backup is provided by the Minecraft Server MCP server (tamo2918/minecraft-server-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
