NeuralNg Component and Theme MCP Server

NeuralNg is an Angular UI component system designed first for code-generating agents and fully usable by human developers. It combines standalone, Signal-native APIs with strict types, accessible native semantics, SSR-safe behavior, headless styling and tree-shakable secondary entry points.

Beta: the current Core release is 0.1.0-beta.8. Public APIs may change before the first stable release.

Why NeuralNg?

• Agent-readable: every public component ships focused README and llms.txt context, while the MCP server exposes component discovery and theme tools.
• Angular-native: standalone components, Signals, strict TypeScript, Angular Forms integration and deterministic hydration.
• Accessible by contract: native semantics, keyboard interaction, focus behavior and accessible names are part of component acceptance.
• Style without lock-in: use Neutral defaults, typed class slots, component tokens or complete unstyled control.
• Package what you use: import from dedicated secondary entry points for predictable, tree-shakable builds.

Quick start

Install the component library and the framework-independent icon set:

npm install @neural-ng/core @neural-ng/icons

Load the icons and a bundled theme in your application styles:

@import '@neural-ng/icons/icons.css';
@import '@neural-ng/core/themes/neutral.css';

Import only the component entry points you need:

import { Component } from '@angular/core';
import { NeuralButton } from '@neural-ng/core/button';
import { NeuralInput } from '@neural-ng/core/input';

@Component({
  selector: 'app-agent-form',
  imports: [NeuralButton, NeuralInput],
  template: `
    <label for="agent-task">Task</label>
    <input neuralInput id="agent-task" placeholder="Describe the task" />
    <neural-button label="Run agent" icon="nt nt-sparkles" />
  `,
})
export class AgentForm {}

See the installation guide for application configuration, theming and SSR setup.

Packages

AI-agent workflow

NeuralNg keeps machine-readable context close to its public APIs. Agents can read the hosted llms.txt, consume the package documentation beside each component, or connect the MCP server:

npx @neural-ng/mcp-server

The server supports bounded discovery and theme recipe operations without granting write access to your application. See the MCP guide for client setup and available resources.

Agent Skills-compatible clients can also install or upload the portable neuralng-angular skill. It teaches an agent to resolve versioned component contracts before generating Angular UI.

Theming

Neutral is the recommended stable source contract. @neural-ng/theme expands a compact neural.theme.json recipe into Core and Editor CSS, a Tailwind v4 bridge, token interchange JSON and diagnostics:

npm install --save-dev @neural-ng/theme
npx neural-theme init
npx neural-theme build

Glass, Futuristic and Mist remain experimental presets while the theme system is in beta. Use Neutral or unstyled for production-sensitive customization.

neural-demo is intentionally retained as a non-production regression laboratory while its broader scenarios are migrated to neural-site. Public documentation belongs in neural-site.

Development

Use Node 24 and npm 11:

npm ci
npm run dev

Before opening a pull request, run the relevant quality gates:

npm run format:check
npm run lint
npm test
npm run build
npm run package:test
npm run docs:verify
npm run e2e:chromium

The package smoke test packs generated npm artifacts and compiles a minimal external consumer. The MCP smoke test validates the published server over stdio, and documentation verification checks package-to-route contracts, installable examples and navigation coverage.

Contributing

Issues, focused pull requests and documentation improvements are welcome. Read CONTRIBUTING.md before starting. Report vulnerabilities privately through the process in SECURITY.md.
