Delete a directory.
AI agents call delete_directory to permanently remove resources in Filesystem MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a directory irreversibly removes all contents and cannot be undone. This is destructive rather than merely Execute because the action destroys data. Severity is high (not critical) because impact is scoped to the filesystem and depends on what directory is targeted, but an AI agent with misdirected arguments could delete critical application or user data.
From the tool's definition Tool name 'delete_directory' and description 'Delete a directory' indicate irreversible removal of data. Sibling tools include 'delete_file', confirming this server exposes destructive operations.
Attacks that exploit this kind of access
Delete a directory. It is categorised as a Destructive tool in the Filesystem MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Filesystem MCP Server MCP server in PolicyLayer and add a rule for delete_directory: 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 Filesystem MCP Server. Nothing to install.
delete_directory 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_directory 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_directory. 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_directory is provided by the Filesystem MCP Server MCP server (njbrake/filesystem-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
delete_directory is one line of Filesystem MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
