Registry and MCP
How the @lumesec registry is laid out, how to browse it from the CLI, and how to give your AI editor access through the shadcn MCP server.
Elements is a standard shadcn registry. Anything that reads shadcn registries can read it: the CLI, the MCP server, v0 and your own tools.
Addresses
| What | URL |
|---|---|
| Item | https://elements.lumesec.ai/r/{name}.json |
| Index of all items | https://elements.lumesec.ai/r/registry.json |
| Namespace | @lumesec |
Item names are the component tags, for example ui-dial, hf-gauge or ln-topology. Shared files are items too, and components list them as dependencies, so the CLI installs each one once:
| Item | What it installs |
|---|---|
lumesec-theme | The --lumesec accent tokens and their Tailwind colours |
lumesec-math, lumesec-color, lumesec-motion, lumesec-canvas | Helpers the React components share: maths, theme colour reading, motion hooks, canvas sizing |
lumesec-pixel-canvas, lumesec-pixel-font, lumesec-sparks, lumesec-roll-text, lumesec-use-controllable-state, lumesec-fuzzy | Building blocks of the Interaction and Pixel UI components |
lumesec-engine-pixel, lumesec-engine-network, lumesec-engine-service | The runtime of each custom-element family |
lumesec-react | Bindings that render custom elements from React |
React components also depend on shadcn's utils item (cn), which every shadcn project already has.
Each collection is an item as well: interaction, pixel-lab, pixel-ui, pixel-hd, network and service-map install every component in it.
Browse from the CLI
npx shadcn@latest search @lumesec --query gauge
npx shadcn@latest view @lumesec/hf-gaugeMCP
The shadcn MCP server lets an editor agent search the registries in your components.json and install items. With @lumesec registered:
npx shadcn@latest mcp init --client claudeOther clients: cursor, vscode, codex, opencode. Then ask, for example, "add a network topology view from the lumesec registry".
Open in v0
Each component page has Open in v0 under Open in. v0 loads the registry item, so you can try the component in a new project.
Pro items
Pro items will be served to holders of a licence key. The registry accepts the key as a header, which the shadcn CLI reads from components.json:
{
"registries": {
"@lumesec": {
"url": "https://elements.lumesec.ai/r/{name}.json",
"headers": { "Authorization": "Bearer ${LUMESEC_KEY}" }
}
}
}The free components never need a key.
