What it can do

Tool names and descriptions exactly as the server reported them on Nov 14, 2026. The maker wrote them, not us; we show them as plain text.

  • check_design

    Check a snippet of CSS, HTML or JSX against the Slop Patterns library and return every AI design anti-pattern it matches, with the fix for each. Covers the 101 documented patterns that have a mechanical tell. Useful for reviewing generated UI code.

  • list_patterns

    List the whole Slop Patterns taxonomy: code, id, name and one-liner for every documented AI design anti-pattern.

  • get_pattern

    Get one full pattern entry by id or code (e.g. "a1" or "the-unchosen-gradient"): what it looks like, why the tools produce it, who it hurts, the fix, sources.

  • changelog

    The library version, what each release added or changed, and how patterns are versioned. Use it to cite a specific version of Slop Patterns.

  • search_patterns

    Plain-language search across the library. "gradient headline" returns A10 Gradient Text Headline.

  • report_pattern

    Report an AI design anti-pattern that is NOT yet in the library, for a design failure seen repeatedly that a search of the library does not find. Reports are reviewed by a human before anything is published, and published entries credit the reporter.

  • why

    Return only the causal explanation for one pattern — which model, tool or template default produces it.

Common questions

Is Slop Patterns safe?

It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 6 days ago, and the latest version (1.2.1) reached the registry 33 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

What can I use instead?

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 534 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.
