Thingadera MCP

The right words for UI patterns, inside your AI tool.

Most back-and-forth with an AI builder is fixing things nobody named. Ask for "a loading state" and you get a spinner. Ask for "a skeleton screen shaped like the result cards" and you get it right the first time. This server gives your AI the names, the rules for when each pattern fits, and a way to do that prep before it writes any UI.

It's the same library and logic as thingadera-f23e191e.base44.app: the full pattern library, the clashes between them, platform and audience rules, and the prep.

Tools

No account, no API key, nothing sent anywhere. It runs on your machine.

Claude Code

claude mcp add thingadera -- npx -y thingadera-mcp

Claude Desktop, Cursor, Windsurf, and others — add this to the MCP config:

{
  "mcpServers": {
    "thingadera": { "command": "npx", "args": ["-y", "thingadera-mcp"] }
  }
}

Get the most out of it

AI tools decide on their own when to call a tool. To make sure yours does the prep first, add one line to your project rules (CLAUDE.md, .cursorrules, or similar):

Before building or changing UI, use the thingadera tools: name each pattern with find_ui_pattern, check the combination, and build from build_ui_prompt.

Does it help?

We tested it blind. Four one-line UI requests were each built twice by the same AI model, once with no tools and once with Thingadera plus the rules line above, and a separate AI judged the drafts without knowing which was which. With Thingadera, three of four drafts came out better: the right overlay for each platform, real buttons and accessible controls, fewer emoji standing in for icons, and data that added up. The one loss (content hidden until you scroll) led to a fix in the build notes, and the rebuilt draft passed the automated checks.

Without the rules line, the model never called the tools. Add it.

Small sample, and AI judging AI. Treat it as a signal, not proof.

Examples

"Add a filter panel to my recipe results page, on phone and desktop. Make it pop."

With Thingadera the AI can look up that a filter panel on phones is usually a bottom sheet and on desktop a drawer, check that a bottom sheet clashes with a floating action button, and replace "make it pop" with something specific, like one accent color used only on the main button.
