Perform actions like move, rename, copy, or delete a file.
AI agents call manageFile 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.
The tool explicitly supports deleting files, which is irreversible. Even though it also supports move, rename, and copy (which are reversible Write-level operations), the presence of delete as a supported action elevates this to Destructive per the 'pick the most severe applicable' rule. Misuse by an AI agent could result in permanent data loss across the accessible filesystem aliases.
From the tool's definition 'delete a file' is listed as one of the actions this tool can perform
Attacks that exploit this kind of access
Perform actions like move, rename, copy, or delete a file. 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 manageFile: 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.
manageFile 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 manageFile 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 manageFile. 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.
manageFile 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.
