WHAT IT DOES

What unity_search_missing_references does on Unity MCP Server

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.

RISK

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 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.
