WHAT IT DOES

What run-luau does on Executor Mcp Roblox

AI agents invoke run-luau to trigger actions in Executor Mcp Roblox. 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 run-luau is rated High

run-luau triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs run-luau safely

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

run-luau Rate-limited

run-luau 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.
