WHAT IT DOES

What update_host_group does on 1Panel MCP Server

AI agents use update_host_group 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_host_group is rated Medium

The tool modifies existing configuration data (host groups) in a reversible manner, fitting the Write category. Severity is medium because misconfiguration could disrupt service routing or DNS resolution, affecting infrastructure availability, but changes are not destructive or financial.

From the tool's definition Tool name 'update_host_group' and description 'Update host group' indicate modification of host group configuration without deletion. The context of 1Panel managing server infrastructure suggests this updates hostnames, DNS records, or server groupings.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

update_host_group Rate-limited

update_host_group 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.
