CSS

You can use the CSS First MCP Server to get intelligent, context-aware CSS solutions tailored to your project. It analyzes your task, detects your framework and build setup, and offers ranked, framework-specific CSS recommendations with optional semantic analysis to help you implement things faster and more reliably.

How to use

Set up your MCP client to include the CSS First server and then start asking for CSS guidance. You will provide a task description like creating a responsive card, centering content, adding dark mode, or implementing advanced container queries. The server will return intelligently ranked CSS suggestions, with optional semantic analysis and implementation guidance tailored to your framework and build environment.

How to install

Prerequisites: Node.js and a working MCP client. Ensure you have access to your project’s MCP configuration area where you register MCP servers.

1. Add the CSS First MCP server to your MCP configuration using the provided command snippet.

2. Restart your MCP client to apply the new server configuration.

Configuration and usage notes

MCP configuration for the CSS First server uses an executable wrapper so your client can communicate with the server. The following stdio configuration runs the server via npx and loads the package for CSS First.

{
  "mcpServers": {
    "css_first": {
      "command": "npx",
      "args": ["-y", "@depthark/css-first"]
    }
  }
}

Examples of tasks you can ask for

• Create a responsive card layout

• Center a div vertically and horizontally

• Add dark mode support

• Make a sticky header
