What is the Stylelint MCP server?

Connect Stylelint to Claude, Cursor or any other MCP client and it stops being a tab you switch to. A mighty CSS linter that helps you avoid errors and enforce conventions. The stylelint mcp server is what makes that connection.

What the server does

  • has over 100 built-in rules for modern CSS syntax and features
  • supports plugins so you can create your own custom rules
  • automatically fixes problems where possible
  • supports shareable configs that you can create or extend
  • can be customized to your exact needs
  • has 15k unit tests making it robust

Installation

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • AboutVision
  • Alumni — The Alumni tool exposed by this server

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Where it fits

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Stylelint's toolset — About, Alumni — is a fair guide to whether it matches your workflow. It is maintained by GitHub Actions; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
