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_designCheck 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_patternsList the whole Slop Patterns taxonomy: code, id, name and one-liner for every documented AI design anti-pattern.
get_patternGet 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.
changelogThe library version, what each release added or changed, and how patterns are versioned. Use it to cite a specific version of Slop Patterns.
search_patternsPlain-language search across the library. "gradient headline" returns A10 Gradient Text Headline.
report_patternReport 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.
whyReturn only the causal explanation for one pattern — which model, tool or template default produces it.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
The registry does not list a required key, though some servers ask you to sign in on first use.
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.
The GitHub repo last changed 6 days ago, and the latest version (1.2.1) reached the registry 33 days ago.
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).

Figma’s official server gives AI your design data so it can turn designs into code or describe them accurately. Connects to Figma’s cloud.
Hosted MCP for Remotion videos: search Remocn components, read docs, plan a video, preview it.
AI video editor for agents: cut footage, add captions and motion graphics, export editable edits.
