# unity_search_missing_references Find all missing/broken object references and missing scripts in the scene. Essential for cleanup and debugging. Agent View of the PolicyLayer registry record for `unity_search_missing_references`. HTML page: https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-search-missing-references ## Facts - Tool: `unity_search_missing_references` - 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: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "unity_search_missing_references", "arguments": {} } } ``` ## Why unity_search_missing_references is rated Low This tool performs scene analysis to detect broken references and missing scripts, which is a diagnostic read operation. It has no side effects: it does not modify assets, delete data, execute scripts, or alter project state. While useful for debugging, misuse by an AI agent would only surface information about existing problems, not create new ones. From the tool's own definition: "Tool description states it 'finds' missing references and missing scripts—a search/query operation with no modification, creation, deletion, or execution of code. The verb 'find' indicates data retrieval only." ## Use case AI agents call unity_search_missing_references to retrieve information from Unity MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. 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_search_missing_references": {} } } ``` ## 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.
