WHAT IT DOES

What unity_amplify_add_node does on Unity MCP Server

AI agents use unity_amplify_add_node 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_amplify_add_node is rated Medium

This tool creates/adds a new node to a shader graph, which is a reversible write operation. It modifies the shader editor state by inserting a new node, but this can be undone. The blast radius is medium since misuse could corrupt shader graphs but is limited to the open shader editor.

RECOMMENDED RULE

The rule that runs unity_amplify_add_node safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Unity MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For unity_amplify_add_node, this is the rule to start with:

unity_amplify_add_node Rate-limited

unity_amplify_add_node stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
