Analyze CSS code for quality, complexity, and design patterns. Returns curated summary by default (lightweight, ~1-2k tokens) or full 150+ metrics with summaryOnly: false. Use this to identify issues, suggest improvements, or audit CSS codebases.
AI agents call analyze_css to retrieve information from CSS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs static analysis of CSS code to produce reports and recommendations. It retrieves and processes information without altering the CSS, executing external operations, or triggering side effects. This is purely informational/advisory in nature, fitting the Read category definition of retrieving or querying data with no side effects.
From the tool's definition Tool analyzes CSS code and returns metrics/summaries without modifying or executing the code. Description states it 'Returns curated summary' and 'identify issues, suggest improvements, or audit' — all read operations.
Documented attack patterns abuse exactly the kind of access analyze_css gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and CSS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for analyze_css:
{
"version": "1",
"default": "deny",
"tools": {
"analyze_css": {}
}
}analyze_css is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

analyze_css 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_css 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_css. 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_css is provided by the CSS MCP Server MCP server (stolinski/css-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
