HTML page: https://policylayer.com/tools/eaveluo-1panel-mcp/update-host-group ## Facts - Tool: `update_host_group` - Server: 1Panel MCP Server (`eaveluo/1panel-mcp`) — https://policylayer.com/tools/eaveluo-1panel-mcp.md - Homepage: https://github.com/EaveLuo/1panel-mcp - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "update_host_group", "arguments": {} } } ``` ## 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 own 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." ## Use case 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. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
