# unity_ui_create_canvas Create a UI Canvas with an EventSystem. Render modes: Agent View of the PolicyLayer registry record for `unity_ui_create_canvas`. HTML page: https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-ui-create-canvas ## Facts - Tool: `unity_ui_create_canvas` - 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_ui_create_canvas", "arguments": {} } } ``` ## Why unity_ui_create_canvas is rated Medium This tool creates new UI elements (Canvas and EventSystem) in a Unity scene, which is a reversible write operation. It modifies the project state by adding new objects but does not execute arbitrary code, delete data, or move financial resources. The blast radius is medium because incorrect canvas creation could require manual cleanup but wouldn't cause data loss or system-level damage. From the tool's own definition: "Tool name 'unity_ui_create_canvas' and description indicate creation of a UI Canvas with EventSystem in a Unity project. The verb 'create' and the context of adding new game objects to a scene demonstrates data creation." ## Use case AI agents use unity_ui_create_canvas 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_ui_create_canvas": { "limits": [ { "counter": "unity_ui_create_canvas_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.
