Delete a world folder. WARNING: This is irreversible! Consider creating a backup first. The server must be stopped.
AI agents call delete_world 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.
This tool irreversibly deletes an entire world folder, which cannot be undone. Despite the warning advising backup creation first, the tool itself performs permanent destruction of game data. This is the most severe category applicable. Severity is critical because misuse by an AI agent could destroy entire game worlds, player progress, builds, and all associated data without recovery.
From the tool's definition Tool description explicitly states 'Delete a world folder. WARNING: This is irreversible!' and requires stopping the server, indicating permanent removal of data.

Delete a world folder. WARNING: This is irreversible! Consider creating a backup first. The server must be stopped. 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 delete_world: 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.
delete_world 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 delete_world 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 delete_world. 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.
delete_world 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.
