# remove_ranges_from_group Remove ranges from a group. Agent View of the PolicyLayer registry record for `remove_ranges_from_group`. HTML page: https://policylayer.com/tools/tjnull-ludus-fastmcp/remove-ranges-from-group ## Facts - Tool: `remove_ranges_from_group` - Server: Ludus FastMCP (`tjnull/ludus-fastmcp`) — https://policylayer.com/tools/tjnull-ludus-fastmcp.md - Homepage: https://github.com/tjnull/Ludus-FastMCP - Risk category: Destructive (Critical risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Hidden ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "remove_ranges_from_group", "arguments": {} } } ``` ## Why remove_ranges_from_group is rated Critical Removing ranges from a group is a destructive operation that severs associations and cannot typically be automatically undone. In a cyber range management context, this could disrupt active security testing environments, affect access controls, and impact ongoing operations. The blast radius is high given the server manages security research environments with potentially many dependent resources. From the tool's own definition: "'Remove ranges from a group' — removes associations between ranges and groups, which may be irreversible depending on system state" ## Use case AI agents call remove_ranges_from_group to permanently remove resources in Ludus FastMCP, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo. ## Recommended policy (PolicyLayer) Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Ludus FastMCP: ```json { "version": "1", "default": "deny", "hide": [ "remove_ranges_from_group" ] } ``` ## Other tools on Ludus FastMCP (230) - `abort_and_remove_range` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/abort-and-remove-range.md - `abort_range_deployment` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/abort-range-deployment.md - `batch_remove_snapshots` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/batch-remove-snapshots.md - `cleanup_old_ranges` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/cleanup-old-ranges.md - `clear_range_access` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/clear-range-access.md - `delete_blueprint` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/delete-blueprint.md - `delete_group` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/delete-group.md - `delete_range` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/delete-range.md - `delete_range_by_user` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/delete-range-by-user.md - `delete_range_object` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/delete-range-object.md - `delete_ranges_by_status` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/delete-ranges-by-status.md - `delete_source` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/delete-source.md - `delete_template` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/delete-template.md - `destroy_vm` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/destroy-vm.md - `remove_snapshot` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/remove-snapshot.md - `remove_user` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/remove-user.md - `remove_users_from_group` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/remove-users-from-group.md - `revoke_range_access` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/revoke-range-access.md - `revoke_range_from_user` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/revoke-range-from-user.md - `rollback_snapshot` — Destructive — https://policylayer.com/tools/tjnull-ludus-fastmcp/rollback-snapshot.md - `abort_template_build` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/abort-template-build.md - `apply_adversary_profile` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/apply-adversary-profile.md - `apply_blueprint_to_range` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/apply-blueprint-to-range.md - `apply_defender_profile` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/apply-defender-profile.md - `batch_power_on_hosts` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/batch-power-on-hosts.md - `batch_snapshot_hosts` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/batch-snapshot-hosts.md - `build_container_based_template` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/build-container-based-template.md - `build_range_from_description` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/build-range-from-description.md - `build_range_from_scratch` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/build-range-from-scratch.md - `build_range_from_skeleton` — Execute — https://policylayer.com/tools/tjnull-ludus-fastmcp/build-range-from-skeleton.md - …and 200 more: https://policylayer.com/tools/tjnull-ludus-fastmcp.md ## For agents This record is a snapshot.
