AI agents call list_style_categories to retrieve information from UI Preset MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and lists design system metadata (categories, descriptions, principles, presets). It has no side effects, creates no resources, executes no code, and modifies nothing. It is a straightforward read operation for discovering available design tokens and categories.
From the tool's definition Tool name is 'list_style_categories' and description states it 'List[s] all available design style categories with descriptions, design principles, and associated presets.' The return value is 'Array of style categories with metadata.' No modification,…

List all available design style categories with descriptions, design principles, and associated presets. Args: - include_presets (boolean): Include preset IDs for each category (default: true) Returns: Array of style categories with metadata. Use with suggest_style and load_preset to explore the design system. It is categorised as a Read tool in the UI Preset MCP Server MCP Server, which means it retrieves data without modifying state.
Register the UI Preset MCP Server MCP server in PolicyLayer and add a rule for list_style_categories: 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 UI Preset MCP Server. Nothing to install.
list_style_categories is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_style_categories 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 list_style_categories. 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.
list_style_categories is provided by the UI Preset MCP Server MCP server (ncsound919/og-glass). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
