WHAT IT DOES

What file_mkdir does on Aapanel

AI agents use file_mkdir to create or update resources in Aapanel, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Aapanel environment.

RISK

Why file_mkdir is rated Medium

This tool creates new directories on the server, which is a reversible write operation. The severity is high because unrestricted directory creation could enable attackers to organize malware, create web-accessible payloads, or fill disk space. However, it is not Destructive (not deletion) and not Execute (not arbitrary code execution). Confidence is high due to clear, unambiguous naming and description.

From the tool's definition Tool name 'file_mkdir' and description 'Create a directory on the server' explicitly indicate filesystem creation/modification without deletion.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs file_mkdir safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Aapanel, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For file_mkdir, this is the rule to start with:

file_mkdir Rate-limited

file_mkdir stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Aapanel, apply this rule, and every file_mkdir call is checked against it from then on.

FAQ

Questions about file_mkdir

What does the file_mkdir tool do? +

Create a directory on the server. It is categorised as a Write tool in the Aapanel MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on file_mkdir? +

Register the Aapanel MCP server in PolicyLayer and add a rule for file_mkdir: 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 Aapanel. Nothing to install.

What risk level is file_mkdir? +

file_mkdir is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit file_mkdir? +

Yes. Add a rate_limit block to the file_mkdir 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.

How do I block file_mkdir completely? +

Set action: deny in the PolicyLayer policy for file_mkdir. 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.

What MCP server provides file_mkdir? +

file_mkdir is provided by the Aapanel MCP server (nipunanirmal/aapanel-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
