WHAT IT DOES

What chown_file does on 1Panel MCP Server

AI agents use chown_file to create or update resources in 1Panel MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 1Panel MCP Server environment.

RISK

Why chown_file is rated Medium

Changing file ownership is a write operation that modifies file metadata. However, it carries high severity because misuse could grant unauthorized users ownership of sensitive files, potentially escalating privileges or locking out legitimate owners. It is reversible (ownership can be changed back), so it falls under Write rather than Destructive.

From the tool's definition 'Change file owner' - modifies file ownership metadata on the filesystem

RECOMMENDED RULE

The rule that runs chown_file safely

PolicyLayer is an MCP gateway: it sits between your AI agents and 1Panel MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For chown_file, this is the rule to start with:

chown_file Rate-limited

chown_file 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.
