WHAT IT DOES

What file_chmod does on Aapanel

AI agents use file_chmod 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_chmod is rated Medium

Modifying file permissions and ownership can grant or restrict access to sensitive files, potentially enabling privilege escalation or exposing protected data. It's a reversible write operation but with high security impact if misused.

RECOMMENDED RULE

The rule that runs file_chmod 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_chmod, this is the rule to start with:

file_chmod Rate-limited

file_chmod 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.

What risk level is file_chmod? +

Can I rate-limit file_chmod? +

Yes. Add a rate_limit block to the file_chmod 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_chmod completely? +
