# unity_component_set_property Set a property value on a component. Supports floats, ints, strings, bools, vectors, colors, and object references. For ObjectReference properties, pass value as: an asset path string, a scene object name string, null to clear, or an object with {assetPath}, {instanceId}, or {gameObject, componentType}.

HTML page: https://policylayer.com/tools/anklebreaker-studio-unity-mcp-server/unity-component-set-property ## Facts - Tool: `unity_component_set_property` - 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_component_set_property", "arguments": {} } } ``` ## Why unity_component_set_property is rated Medium This tool modifies component properties in the Unity Editor, which creates or changes data reversibly. It does not execute arbitrary code or delete data, placing it in the Write category. Severity is high because modifying component properties could break game functionality, affect multiple scene objects, or corrupt project state if misused by an AI agent without proper understanding of the game architecture. From the tool's own definition: "Tool description states it 'Set[s] a property value on a component' supporting modification of floats, ints, strings, bools, vectors, colors, and object references. This is reversible modification of component properties in Unity projects." ## Use case AI agents use unity_component_set_property 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**.
