# set_group_whole_ban Mute all members in group Agent View of the PolicyLayer registry record for `set_group_whole_ban`. HTML page: https://policylayer.com/tools/1021143806-napcat-mcp/set-group-whole-ban ## Facts - Tool: `set_group_whole_ban` - Server: NapCat MCP Server (`1021143806/napcat_mcp`) — https://policylayer.com/tools/1021143806-napcat-mcp.md - Homepage: https://github.com/1021143806/napcat_mcp - Risk category: Execute (High 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": "set_group_whole_ban", "arguments": {} } } ``` ## Why set_group_whole_ban is rated High This tool executes a moderation action (whole-group mute) that affects all members of a group simultaneously. It is a reversible administrative action (mute can be lifted), so it falls under Execute rather than Destructive. However, the blast radius is high as it silences an entire group's membership instantly. From the tool's own definition: "'Mute all members in group' — triggers a group-wide ban/mute operation affecting all members of a QQ group" ## Use case AI agents invoke set_group_whole_ban to trigger actions in NapCat MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches NapCat MCP Server: ```json { "version": "1", "default": "deny", "tools": { "set_group_whole_ban": { "limits": [ { "counter": "set_group_whole_ban_rate", "window": "minute", "max": 10, "scope": "grant" } ] } } } ``` ## Other tools on NapCat MCP Server (56) - `delete_essence_msg` — Destructive — https://policylayer.com/tools/1021143806-napcat-mcp/delete-essence-msg.md - `delete_group_file` — Destructive — https://policylayer.com/tools/1021143806-napcat-mcp/delete-group-file.md - `delete_msg` — Destructive — https://policylayer.com/tools/1021143806-napcat-mcp/delete-msg.md - `set_group_kick` — Destructive — https://policylayer.com/tools/1021143806-napcat-mcp/set-group-kick.md - `set_group_ban` — Execute — https://policylayer.com/tools/1021143806-napcat-mcp/set-group-ban.md - `can_send_image` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/can-send-image.md - `can_send_record` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/can-send-record.md - `get_cookies` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-cookies.md - `get_credentials` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-credentials.md - `get_csrf_token` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-csrf-token.md - `get_essence_msg_list` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-essence-msg-list.md - `get_forward_msg` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-forward-msg.md - `get_friend_list` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-friend-list.md - `get_friend_msg_history` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-friend-msg-history.md - `get_group_announcement_list` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-announcement-list.md - `get_group_at_all_remain` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-at-all-remain.md - `get_group_file_system_info` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-file-system-info.md - `get_group_file_url` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-file-url.md - `get_group_files_by_folder` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-files-by-folder.md - `get_group_honor_info` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-honor-info.md - `get_group_ignore_add_request` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-ignore-add-request.md - `get_group_info` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-info.md - `get_group_info_ex` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-info-ex.md - `get_group_list` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-list.md - `get_group_member_info` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-member-info.md - `get_group_member_list` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-member-list.md - `get_group_msg_history` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-msg-history.md - `get_group_root_files` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-root-files.md - `get_group_system_msg` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-group-system-msg.md - `get_image` — Read — https://policylayer.com/tools/1021143806-napcat-mcp/get-image.md - …and 26 more: https://policylayer.com/tools/1021143806-napcat-mcp.md ## For agents This record is a snapshot.
