AI agents invoke ux_review to trigger processes or run actions in Screenshotsmcp. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
ux_review can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

Run an AI-powered UX review on any URL. Captures a screenshot and analyzes it along with accessibility tree, SEO metadata, and performance metrics using Kimi k2.5 vision. Returns actionable UX feedback across categories: Accessibility, SEO, Performance, Navigation, Content, and Mobile-friendliness.. It is categorised as a Execute tool in the Screenshotsmcp MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Screenshots MCP server in PolicyLayer and add a rule for ux_review: 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 Screenshotsmcp. Nothing to install.
ux_review is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the ux_review 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 ux_review. 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.
ux_review is provided by the Screenshots MCP server (relievedattention992-smithery/screenshotsmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
