# add_host_list_to_deploy_group [application delivery] Add host list to deploy group Agent View of the PolicyLayer registry record for `add_host_list_to_deploy_group`. HTML page: https://policylayer.com/tools/alibabacloud-devops/add-host-list-to-deploy-group ## Facts - Tool: `add_host_list_to_deploy_group` - Server: Alibabacloud Devops (`alibabacloud-devops-mcp-server`) — https://policylayer.com/tools/alibabacloud-devops.md - Install: `npx -y alibabacloud-devops-mcp-server` - Homepage: git+ssh://git@github.com/aliyun/alibabacloud-devops-mcp-server.git - 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": "add_host_list_to_deploy_group", "arguments": {} } } ``` ## Why add_host_list_to_deploy_group is rated Medium This tool creates or modifies deployment infrastructure configuration by adding hosts to a deploy group. While it modifies state, the action is reversible (hosts can be removed), so it does not qualify as Destructive. It is not an Execute tool because it does not run code or trigger arbitrary operations — it configures deployment targets. From the tool's own definition: "Tool name and description indicate 'Add host list to deploy group' — a modification operation that adds hosts to a deployment configuration. The verb 'add' and the context of deployment groups suggests reversible data modification." ## Use case AI agents use add_host_list_to_deploy_group to create or update resources in Alibabacloud Devops, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Alibabacloud Devops environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
