# unity_probuilder_flip_normals Flip (reverse) the winding of every face so the mesh renders inside-out. Useful for skyboxes / interior shells. Agent View of the PolicyLayer registry record for `unity_probuilder_flip_normals`. HTML page: https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-probuilder-flip-normals ## Facts - Tool: `unity_probuilder_flip_normals` - Server: Unity MCP Server (`anklebreaker-studio/unity-mcp-server`) — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server.md - Homepage: https://github.com/AnkleBreaker-Studio/unity-mcp-server - 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": "unity_probuilder_flip_normals", "arguments": {} } } ``` ## Why unity_probuilder_flip_normals is rated Medium This tool modifies mesh data (face winding/normals) which constitutes a Write operation—it changes asset properties reversibly without deleting data. Severity is medium because while it could corrupt visual appearance of 3D models if applied incorrectly, the modification is easily undone (flip again or undo). The impact is scoped to individual mesh assets rather than project-wide destruction. From the tool's own definition: "Tool description explicitly states it will 'flip (reverse) the winding of every face' and 'mesh renders inside-out', which modifies mesh geometry data." Risk signals: Bulk/mass operation — affects multiple targets ## Use case AI agents use unity_probuilder_flip_normals to create or update resources in Unity MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Unity MCP Server environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Unity MCP Server: ```json { "version": "1", "default": "deny", "tools": { "unity_probuilder_flip_normals": { "limits": [ { "counter": "unity_probuilder_flip_normals_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Unity MCP Server (337) - `unity_amplify_remove_node` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-amplify-remove-node.md - `unity_animation_remove_curve` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-animation-remove-curve.md - `unity_animation_remove_event` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-animation-remove-event.md - `unity_animation_remove_keyframe` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-animation-remove-keyframe.md - `unity_animation_remove_layer` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-animation-remove-layer.md - `unity_animation_remove_parameter` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-animation-remove-parameter.md - `unity_animation_remove_state` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-animation-remove-state.md - `unity_animation_remove_transition` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-animation-remove-transition.md - `unity_asset_delete` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-asset-delete.md - `unity_component_remove` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-component-remove.md - `unity_console_clear` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-console-clear.md - `unity_editorprefs_delete` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-editorprefs-delete.md - `unity_gameobject_delete` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-gameobject-delete.md - `unity_input_remove_action` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-input-remove-action.md - `unity_input_remove_map` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-input-remove-map.md - `unity_navmesh_clear` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-navmesh-clear.md - `unity_packages_remove` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-packages-remove.md - `unity_playerprefs_delete` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-playerprefs-delete.md - `unity_playerprefs_delete_all` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-playerprefs-delete-all.md - `unity_prefab_remove_component` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-prefab-remove-component.md - `unity_prefab_remove_gameobject` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-prefab-remove-gameobject.md - `unity_probuilder_delete_faces` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-probuilder-delete-faces.md - `unity_scene_new` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-scene-new.md - `unity_shadergraph_remove_node` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-shadergraph-remove-node.md - `unity_spriteatlas_delete` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-spriteatlas-delete.md - `unity_terrain_clear_detail` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-terrain-clear-detail.md - `unity_terrain_clear_trees` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-terrain-clear-trees.md - `unity_terrain_remove_layer` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-terrain-remove-layer.md - `unity_terrain_remove_tree_prototype` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-terrain-remove-tree-prototype.md - `unity_undo_clear` — Destructive — https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-undo-clear.md - …and 307 more: https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server.md ## For agents This record is a snapshot.
