Overview

Description from the maker (original English)

Search, read and install agent-ready React components, screens and blocks for AI products.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Search & AI memory
  • You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http affectui https://www.affectui.com/api/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "affectui": {
      "url": "https://www.affectui.com/api/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "affectui": {
      "type": "http",
      "url": "https://www.affectui.com/api/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • Authorization secret HTTP header
    Optional. "Bearer aui_…" with your affectUI Pro access key (Account → Downloads) to get the source of Pro items. Free items and all docs work without it.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is affectUI safe?

It passed 1 of 1 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?

You need to fill in: Authorization

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 –, and the latest version (1.0.0) reached the registry 28 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 in developer mode.

What can I use instead?

In the same category: Context7, Codebase Memory, Exa

UI for AI agents. affectUI is a library of React components for what agents do – runs, tool calls, traces, handoffs, approvals and context – and for the rest of your app: inputs, menus, charts, screens, illustrations and motion. Every item is one `.tsx` file with its styles inside: no Tailwind, no CSS setup, no animation library. Install it with the shadcn CLI, or let Claude Code, Cursor or Codex add it through the MCP server, and it is source you own.

Showcase

Why affectUI

  • Made for agents. Components for what agents actually do: trees of sub-agents, tool calls, traces with cost per step, handoffs, approvals and the context window – live states, not static mockups.
  • Agent-ready. An MCP server and llms.txt let Claude Code, Cursor, Codex or v0 find and add items for you.
  • One file each. Every component is a single .tsx file with its styles inside. Nothing to configure, no CSS framework required.
  • Motion that feels finished. Morphs, staggered reveals, rolling numbers and smooth state changes, and all of it respects prefers-reduced-motion.
  • Dark mode built in. Each item switches when an ancestor has the class dark or data-theme="dark".
  • Accessible by default. Real buttons, labels, keyboard support and live regions where they matter.
  • Responsive. Container queries, so items adapt to the space they get, not just the window.

Install

Requirements
  • React 19, with or without TypeScript
  • Any React setup: Next.js, Vite, Remix or plain React
  • The @/* import alias if you use the shadcn CLI (Next.js and shadcn set it up by default)
With the shadcn CLI

Every item has its own registry URL. Run the command from its page on affectui.com or from the tables below:

npx shadcn@latest add https://www.affectui.com/r/reaction-bar.json

The file lands in components/ui, ready to import.

Prefer short names? Register the namespace once in components.json:

{

"registries": { "@affectui": "https://www.affectui.com/r/{name}.json" } }

npx shadcn@latest add @affectui/reaction-bar
Copy and paste

Open the item's folder in this repository (components/, illustrations/ or motion/), copy the file into your project and import it. That's all it takes.

Usage

import { ReactionBar } from "@/components/ui/reaction-bar";

export function PostActions({ post }) { return ( api.react(post.id, key, state.active)} /> ); }

Props, keyboard support and accessibility notes for every item are on its page, e.g. Reaction Bar.

Use it with AI tools

affectUI is agent-ready. Connect the MCP server once and Claude Code, Cursor, VS Code or Codex can search every item, read its docs and add it for you:

claude mcp add --transport http affectui https://www.affectui.com/api/mcp

Other clients: add { "mcpServers": { "affectui": { "url": "https://www.affectui.com/api/mcp" } } } to their MCP config. Without any setup, point your assistant at llms.txt or llms-full.txt. Every page on affectui.com also has a Copy prompt bar for Claude, ChatGPT / Codex, Cursor and v0. Setup details: Using with AI.
