WHAT IT DOES

What unity_editorprefs_set does on Unity MCP Server

AI agents use unity_editorprefs_set 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_editorprefs_set is rated Medium

This tool modifies editor preferences reversibly—settings can be changed back or reset. It creates or updates configuration data rather than executing arbitrary code or deleting data. While it could affect editor behavior or project configuration, the changes are not destructive and can be undone, placing it in the Write category.

From the tool's definition Tool name contains 'set' and description states 'Set an EditorPrefs value'; EditorPrefs are persistent configuration settings in Unity that modify editor behavior and project state.
