Why superdesign_live_gallery needs a policy

The tool executes a server process that watches files and serves content in real-time. This is an Execute category action because it triggers an external operation (server startup) whose behavior and side effects are dependent on how it's invoked. While the operation is not destructive and doesn't involve financial transactions, it does launch and control a running process.

From the tool's definition 'Start a live gallery server with real-time updates and file watching' — this tool initiates and runs a server process, which is an external operation whose effects depend on arguments (port selection, file paths monitored, server configuration).

POLICY

How to control superdesign_live_gallery

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "superdesign_live_gallery": {
      "limits": [
        {
          "counter": "superdesign_live_gallery_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

superdesign_live_gallery 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.

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