Remove directory and all its contents.
AI agents call rmdir to permanently remove resources in MCP File System Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently deletes directories and all contained data without recovery options. It cannot be undone and represents significant data loss risk, making it Destructive rather than Write. The high severity reflects the potential for cascading data loss across multiple files and subdirectories.
From the tool's definition Tool name 'rmdir' and description 'Remove directory and all its contents' indicate irreversible deletion of directories and files.
Attacks that exploit this kind of access
Remove directory and all its contents. It is categorised as a Destructive tool in the MCP File System Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MCP File System Server MCP server in PolicyLayer and add a rule for rmdir: 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 MCP File System Server. Nothing to install.
rmdir 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 rmdir 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 rmdir. 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.
rmdir is provided by the MCP File System Server MCP server (kvas-it/mcp-server-fs). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
