The explicit 'read-only' designation confirms it has no capability to alter state or trigger external operations. Low severity because query access poses minimal risk even if misused by an agent.

From the tool's definition Tool name 'roblox_get' and description 'Read-only queries against the Roblox Studio scene' explicitly indicate retrieval without side effects.

POLICY

How to control roblox_get

PolicyLayer is an MCP gateway — it sits between your AI agents and Roblox Studio MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for roblox_get:

policy.json

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

roblox_get is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Roblox Studio MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
