WHAT IT DOES

What trace_material_connection does on Unreal-MCP

AI agents call trace_material_connection to retrieve information from Unreal-MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why trace_material_connection is rated Low

The name implies tracing (following/reading) a connection between nodes in a material graph, which is a read operation. However, the empty description lowers confidence. Given the server context (Unreal Engine editor control), misuse could affect material assets, warranting medium severity.

From the tool's definition Tool name 'trace_material_connection' suggests reading/querying connection data in a material graph. Description is empty and uninformative.

RECOMMENDED RULE

The rule that runs trace_material_connection safely

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

trace_material_connection Allowed

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "trace_material_connection": {}
  }
}

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

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