WHAT IT DOES

What unity_input_add_binding does on Unity MCP Server

AI agents use unity_input_add_binding 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_binding is rated Medium

This tool creates or modifies input binding configurations in Unity's input system. While the change is reversible (bindings can be removed or reassigned), it affects application behavior and could disrupt game controls if misconfigured by an agent. It does not execute arbitrary code, delete data irreversibly, or move money, making Write the appropriate category.

From the tool's definition Tool name 'unity_input_add_binding' and description 'Add a simple (non-composite) binding to an action' indicates creation/modification of input configuration data. The verb 'Add' and context of binding configuration demonstrates reversible data modification.
