Perform actions like create, rename, or delete a folder.
AI agents call manageFolder to permanently remove resources in BetterMCPFileServer — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Because this tool supports destructive operations (deleting a folder and presumably all its contents), it must be classified at the highest applicable severity. While it also supports non-destructive actions (create, rename), the most severe capability — irreversible folder deletion — drives the classification. An AI agent misusing this tool could permanently destroy entire directory trees, warranting high severity.
From the tool's definition 'delete a folder' — the tool explicitly supports folder deletion, which is irreversible
Attacks that exploit this kind of access
Perform actions like create, rename, or delete a folder. It is categorised as a Destructive tool in the BetterMCPFileServer MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the BetterMCPFileServer MCP server in PolicyLayer and add a rule for manageFolder: 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 BetterMCPFileServer. Nothing to install.
manageFolder 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 manageFolder 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 manageFolder. 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.
manageFolder is provided by the BetterMCPFileServer MCP server (martinschlott/bettermcpfileserver). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
