# rhino_undo Undo the last operation(s) in the Rhino document. Agent View of the PolicyLayer registry record for `rhino_undo`. HTML page: https://policylayer.com/tools/easehee-rhino-mcp/rhino-undo ## Facts - Tool: `rhino_undo` - Server: Rhino (`easehee/rhino-mcp`) — https://policylayer.com/tools/easehee-rhino-mcp.md - Homepage: https://github.com/EaseHee/rhino-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": "rhino_undo", "arguments": {} } } ``` ## Why rhino_undo is rated Medium While undo can revert destructive actions, it is itself a reversible modification tool—not destructive, since undo operations themselves can be undone (via redo). It falls under Write rather than Destructive because the modification is intentionally reversible. The severity is medium because an AI agent repeatedly calling undo could erase user work, but the user can undo the undo, mitigating full data loss. From the tool's own definition: "The tool name 'rhino_undo' and description 'Undo the last operation(s) in the Rhino document' indicate it modifies the state of the Rhino document by reverting changes. Undo is a reversible operation that alters document state." ## Use case AI agents use rhino_undo to create or update resources in Rhino, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Rhino environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Rhino: ```json { "version": "1", "default": "deny", "tools": { "rhino_undo": { "limits": [ { "counter": "rhino_undo_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Rhino (244) - `gh_delete_component` — Destructive — https://policylayer.com/tools/easehee-rhino-mcp/gh-delete-component.md - `gh_reset` — Destructive — https://policylayer.com/tools/easehee-rhino-mcp/gh-reset.md - `rhino_bim_pset_delete` — Destructive — https://policylayer.com/tools/easehee-rhino-mcp/rhino-bim-pset-delete.md - `rhino_layer_delete` — Destructive — https://policylayer.com/tools/easehee-rhino-mcp/rhino-layer-delete.md - `rhino_object_delete` — Destructive — https://policylayer.com/tools/easehee-rhino-mcp/rhino-object-delete.md - `rhino_render_queue_cancel` — Destructive — https://policylayer.com/tools/easehee-rhino-mcp/rhino-render-queue-cancel.md - `gh_new_canvas` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/gh-new-canvas.md - `gh_run` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/gh-run.md - `gh_run_template` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/gh-run-template.md - `rhino_annotation_scale_bar` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-annotation-scale-bar.md - `rhino_attractor_displace_points` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-attractor-displace-points.md - `rhino_axis_ribs` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-axis-ribs.md - `rhino_batch_call` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-batch-call.md - `rhino_boolean_intersection` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-boolean-intersection.md - `rhino_boolean_union` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-boolean-union.md - `rhino_bridge_select_instance` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-bridge-select-instance.md - `rhino_display_mode_set` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-display-mode-set.md - `rhino_drawing_section_cut` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-drawing-section-cut.md - `rhino_execute_csharp` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-execute-csharp.md - `rhino_execute_python` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-execute-python.md - `rhino_mesh_boolean_union` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-mesh-boolean-union.md - `rhino_network_surface` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-network-surface.md - `rhino_object_select` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-object-select.md - `rhino_render_queue_submit` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-render-queue-submit.md - `rhino_render_to_file` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-render-to-file.md - `rhino_section` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-section.md - `rhino_section_at_axis` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-section-at-axis.md - `rhino_shell` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-shell.md - `rhino_skin_from_sections` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-skin-from-sections.md - `rhino_taper` — Execute — https://policylayer.com/tools/easehee-rhino-mcp/rhino-taper.md - …and 214 more: https://policylayer.com/tools/easehee-rhino-mcp.md ## For agents This record is a snapshot.
