THE RISK

High Risk

This tool takes input (a sketch) and triggers an external API operation to generate/transform it into an image. It executes a generation process via Stability AI's API with effects dependent on the input arguments. It's not purely a read operation, and while it writes output, the primary action is executing an AI image generation pipeline on an external service.

HOW TO CONTROL STABILITY-AI-CONTROL-SKETCH

PolicyLayer is an MCP gateway — it sits between your AI agents and Stability AI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for stability-ai-control-sketch:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "stability-ai-control-sketch": {
      "limits": [
        {
          "counter": "stability-ai-control-sketch_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

stability-ai-control-sketch 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 Stability AI 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.
