WHAT IT DOES

What unity_shadergraph_open does on Unity MCP Server

RECOMMENDED RULE

The rule that runs unity_shadergraph_open 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_shadergraph_open, this is the rule to start with:

unity_shadergraph_open Allowed

unity_shadergraph_open is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Unity MCP Server, apply this rule, and every unity_shadergraph_open call is checked against it from then on.
