WHAT IT DOES

What set_niagara_scratch_pad_hlsl does on Unreal-MCP

AI agents invoke set_niagara_scratch_pad_hlsl to trigger actions in Unreal-MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why set_niagara_scratch_pad_hlsl is rated High

The tool name suggests it sets HLSL (High Level Shader Language) code in the Niagara VFX scratch pad, which effectively executes arbitrary GPU shader code. This falls under Execute due to the code execution aspect. Confidence is reduced due to the empty description, but the HLSL component strongly implies code execution capability.

From the tool's definition Tool name 'set_niagara_scratch_pad_hlsl' implies writing/executing HLSL shader code in Niagara's scratch pad; no description provided.

RECOMMENDED RULE

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

set_niagara_scratch_pad_hlsl Rate-limited

set_niagara_scratch_pad_hlsl stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
