WHAT IT DOES

What update_device_hosts does on 1Panel MCP Server

AI agents use update_device_hosts 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 update_device_hosts is rated Medium

This tool modifies the hosts file (or equivalent DNS configuration), which is a reversible but impactful change to system networking behavior. It affects how the device resolves domain names and could redirect traffic, disable services, or cause connectivity issues if misconfigured. The risk is high due to potential for widespread system impact, but it is reversible (Write rather than Destructive).

From the tool's definition Tool name 'update_device_hosts' and description 'Update device hosts' indicates modification of the hosts file or DNS resolution configuration on the device.

RECOMMENDED RULE

The rule that runs update_device_hosts safely

update_device_hosts Rate-limited

update_device_hosts 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.
