AI agents call analyze_design_references to retrieve information from Ui without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though analyze_design_references only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Analyze design references from URLs (browser automation + screenshots) and/or attached images. Extracts colors, typography, layout patterns, and UI components. When multiple references are provided, identifies common patterns across all sources to prioritize consistent design decisions for UI/UX generation.. It is categorised as a Read tool in the Ui MCP Server, which means it retrieves data without modifying state.
Register the Ui MCP server in PolicyLayer and add a rule for analyze_design_references: 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. Nothing to install.
analyze_design_references 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 analyze_design_references 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 analyze_design_references. 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.
analyze_design_references is provided by the Ui MCP server (@forgespace/ui-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
