Generate a new image in the style of a reference image
AI agents use stability-ai-control-style to create or update resources in Stability AI MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Stability AI MCP Server environment.
This tool creates new images based on style reference inputs. Image generation is a Write operation as it produces new digital assets that can be modified or deleted. Severity is medium because misuse could result in unwanted image generation (resource consumption, reputation harm from generated content) but lacks the irreversibility of Destructive operations or financial impact.
From the tool's definition Tool name includes 'generate' and description states 'Generate a new image', indicating creation of new digital content. This is a reversible operation (generated images can be deleted or regenerated) rather than destructive.

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-style:
{
"version": "1",
"default": "deny",
"tools": {
"stability-ai-control-style": {
"limits": [
{
"counter": "stability-ai-control-style_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}stability-ai-control-style stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Generate a new image in the style of a reference image. It is categorised as a Write tool in the Stability AI MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Stability AI MCP Server MCP server in PolicyLayer and add a rule for stability-ai-control-style: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Stability AI MCP Server. Nothing to install.
stability-ai-control-style is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the stability-ai-control-style rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for stability-ai-control-style. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
stability-ai-control-style is provided by the Stability AI MCP Server MCP server (tadasant/mcp-server-stability-ai). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
