Slop Patterns

Checks UI code for AI-default design patterns and gives the fix. By Precious Studio.

Power your agent

Add this server

The publisher's own URL. Not a PlugMCP endpoint.

Server URL
https://sloppatterns.com/mcp
Provider
Add in Claude

Claude opens with the name and URL filled in. You still confirm it there.

Claude Code
claude mcp add --transport http com.sloppatterns-slop-patterns https://sloppatterns.com/mcp

Run in a terminal.

Claude Desktop
{
  "mcpServers": {
    "com.sloppatterns-slop-patterns": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://sloppatterns.com/mcp"
      ]
    }
  }
}

Remote URL or a command on your machine? How the two installs differ

Host a copy with our keys and logs.

A new server you create. It is not this listing's official endpoint. Use the publisher install when you want their URL and their credentials.

Checks UI code for AI-default design patterns and gives the fix. By Precious Studio.

Slop Patterns

A public library of AI design anti-patterns: what they look like, why the tools produce them, and what to do instead. Live at sloppatterns.com.

  • License: MIT (LICENSE). Only the pattern library is here and MIT: patterns.json, the pattern text and sources, the site, and the MCP server in api/.
  • Scanner code is not open. The Slop Score scanner at sloppatterns.com/score (browser capture, live checks and grading) is a separate project and is not included in this repo.
  • The MCP server runs at https://sloppatterns.com/mcp. No account or key. See the "For agents" page on the site.
  • The research note, The Same Page, is in research/.

Maintained by Pavithra Lamahewa at Precious Studio. Suggest a pattern from the site, or open an issue.

Use it in your AI tools

Your coding agent calls check_design on the UI it writes and fixes what it finds before you see it.

  • Claude Code (plugin, MCP plus a skill): 
    /plugin marketplace add pavithralamahewa/slop-patterns
/plugin install slop-patterns@slop-patterns
  • Any MCP client: npx add-mcp https://sloppatterns.com/mcp, or add an HTTP server with that URL. It is in the official MCP Registry as com.sloppatterns/slop-patterns.
  • Cursor: add the server in Settings → MCP (type HTTP, URL above), then copy cursor/slop-patterns.mdc into .cursor/rules/.

Use the taxonomy

Every pattern has a stable code (for example A10) and a stable URL (https://sloppatterns.com/#gradient-text-headline). Codes never change meaning; when an entry is revised, its version and updated fields change.

  • All 272 patterns as data: taxonomy.json. Each entry says whether it is checked automatically (101 are; the scanner, the MCP server and the command line share 104 code rules, and 57 of them have passed a hand audit on whole pages) or needs a person.
  • Command line: npx slop-patterns check ./dist or npx slop-patterns scan example.com. See cli/.
  • One rule set: the scanner, the MCP server and the command line run the same rules.js, so they never disagree.
  • Cite it: see CITATION.cff. GitHub shows a "Cite this repository" button from it.
How do I install Slop Patterns?
Copy the http config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.
Does Slop Patterns need an API key?
No required environment variable is listed on this record.
What transport does Slop Patterns use?
Slop Patterns is reached over HTTP.
When was Slop Patterns last checked?
Last checked 2026-10-16. Checks UI code for AI-default design patterns and gives the fix. By Precious Studio.
