WHAT IT DOES

What unity_scriptableobject_set_field does on Unity MCP Server

AI agents use unity_scriptableobject_set_field 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_scriptableobject_set_field is rated Medium

This tool creates or modifies data reversibly within Unity ScriptableObject assets. While it changes asset state, the modification is non-destructive and can be undone. The severity is medium because misuse could corrupt game configuration, data structures, or asset settings in ways requiring rework, but the effects are confined to the asset itself and potentially reversible through version control or undo…

From the tool's definition Tool name includes 'set_field' and description states 'Set a field value on a ScriptableObject asset', indicating modification of data.
