WHAT IT DOES

What unity_input_add_action does on Unity MCP Server

AI agents use unity_input_add_action 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_input_add_action is rated Medium

This tool creates or modifies an Input Action Asset by adding a new action entry. This is a Write operation because it creates new configuration data that is reversible (the action can be removed or modified later). It does not execute code, delete data, or move resources, so it does not qualify as Execute, Destructive, or Financial.

From the tool's definition The tool name is 'unity_input_add_action' and the description states it will 'Add an action to an action map in an Input Action Asset.' The verb 'Add' indicates creation of new data within a game project configuration file.
