THE RISK

Low Risk

Why search_styles needs a policy

This tool performs a search/query action to discover and list available styling options. It does not create, modify, delete, execute arbitrary operations, move funds, or cause irreversible changes. The blast radius of misuse is minimal—an agent might request excessive searches or inappropriate styles, but cannot generate unauthorized content, delete data, or cause financial harm through this tool alone.

From the tool's definition Tool description states it 'Search[es] for styles/LoRAs' — a query operation that retrieves available style options for use in image generation with no side effects or data modification.

POLICY

How to control search_styles

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

policy.json

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

search_styles 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 Krea 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.
