WHAT IT DOES

What unity_asmdef_set_platforms does on Unity MCP Server

AI agents use unity_asmdef_set_platforms 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.

RISK

Why unity_asmdef_set_platforms is rated Medium

This tool modifies assembly definition metadata (includePlatforms/excludePlatforms lists) which are configuration settings that affect how code is compiled and included in builds. This is a reversible Write operation — the settings can be changed back. It does not execute code or irreversibly delete data, but it does alter project configuration that affects the build system.

From the tool's definition unity_asmdef_set_platforms: 'Set the include/exclude platform lists for an assembly definition' — modifies assembly definition configuration by setting platform inclusion/exclusion lists.
