EneUI MCP

English · Italiano

A UI catalogue over MCP: 109,000+ React / Tailwind / shadcn components, 1,556 composed blocks and 12,000+ icons — with the source, the declared licence and a one-line install command on every record.

The endpoint is hosted. This repo carries the manifest, the client setup and the examples; the catalogue itself is not redistributed here.

Listed in the official MCP registry as io.github.eneui/eneui-mcp.

• Transport: Streamable HTTP (JSON-RPC 2.0)

• Auth: none for reading (per-IP rate limit); OAuth 2.1 + PKCE for paid tiers

• No API key, no signup, no install for the remote server

Why this exists

Copying a component from GitHub is free and takes two clicks. What it does not give you is the answer to the question that stops an invoice: may I ship this to my client? The repository usually has a licence file, sometimes it has none, and nobody reads it before delivery.

check_licence reads that file, detects the SPDX id, stores the sha256 and the date, and says whether the library can travel inside a client project. That is the whole product.

Cursor / any client with a JSON config

{
  "mcpServers": {
    "eneui": {
      "type": "streamable-http",
      "url": "https://ui.eneawork.it/mcp"
    }
  }
}

No client at all — runnable script: examples/curl.sh, or inline:

curl -s https://ui.eneawork.it/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'

Tools

check_licence is the reason this server exists: every other catalogue tells you a component exists, none tells you whether the licence travels with it.

Prompts that work

Search EneUI for a three-tier pricing section with an annual toggle,
then check the licence of the library it comes from.

Build a landing page: hero, logos, features, pricing, FAQ, footer.
Use compose_page, then get_block for each one.

Before I ship this repo to a client, check the licence of every library
in package.json.

More, with the shape of a good answer: examples/prompts.md (Italian: examples/prompts.it.md).

What this repo is not

• Not a dump of the catalogue. The records belong to the libraries that published them and keep their upstream licence.

• Not a legal opinion. check_licence reports what a licence file says, with the hash that proves which file was read.

• Not the crawler.
