Atheros AI Builder: 350+ UI Components & MCP for Devs — 2026 Guide

Generate components against your design system

Atheros generates new UI components with AI that are reviewed, validated, and shipped as code — over MCP or to Figma. Every component is generated against your design system, so there is no AI slop.

On-brand, polished components instead of random AI output

350+ production-ready components

Search a growing UI collection with search_components. Your agent finds the template that fits and writes it into your project directly over the Atheros MCP, with the component context and your design system applied automatically.

Build high-quality frontend faster with ready components

Connect Claude Code, Cursor or Codex

Connect Claude Code, Cursor or Codex to the Atheros MCP and let your agent work with your components directly. Add it with a single command: claude mcp add atheros --transport http https://mcp.atheros.ai/v1.

Your AI agent pulls and writes real component files into your project

Your own private UI collection

Generate a whole private component library, then pull it back into any project with get_component — the same way you reach for a catalogue template.

Reuse your own components across every project

Validate against Design.md and Builder.md

validate_project runs the automated tests and checks the output against your design system. Your Builder.md guidelines keep every component in line with the rest of your project.

Consistent components that match your project guidelines

Export directly to Figma as real layers

Copy any component in the builder and paste it into the Atheros Figma plugin. It lands as real Figma layers — auto-layout, text and styling intact — with every element as a named layer inside auto-layout frames, styling carried across, and every breakpoint or exactly the current view.

Your design team works from what was actually built

• Large production-ready component libraryAtheros offers 350+ production-ready components, with new components added every week. The library spans categories including navigation, forms, tables, messaging, chat, AI, pricing, dashboards, sidebars, authentication, and more, available in React and Vanilla.
• AI agents connect directly to your components via MCPYou can connect Claude Code, Cursor, or Codex to the Atheros MCP and let your agent work with your components directly. Agents can search the UI collection with search_components, pull templates into your project, and generate a private component library retrievable with get_component.
• Design-system-aware generation and validationEvery component is generated against your design system, reviewed, validated, and shipped as code. validate_project runs automated tests and checks output against your design system, while Builder.md guidelines keep every component in line with the rest of your project.
• Figma export with real layersCopy any component in the builder and paste it into the Atheros Figma plugin. It lands as real Figma layers with auto-layout, text, and styling intact. Every element arrives as a named layer inside auto-layout frames with hug and fill sizing, and colors, gradients, shadows, corner radii, and typography carry across.

• Figma export availability varies by planThe pricing page lists 'Export components to Figma (coming soon)' under the Atheros AI Pass tier, while the homepage states 'Figma export has been launched.' Confirm current availability for your specific plan before relying on it.
• AI credits do not roll overMonthly AI credits refresh each billing cycle and do not roll over. Only separately purchased credit packs never expire, and you need at least an Atheros AI Pass subscription to spend purchased packs.
• Component and project limits differ by tierFree allows up to 5 of your own components and 100 AI credits/month. Atheros AI Pass allows up to 100 components and 4 projects with 750 credits/month. Atheros AI Ultra allows up to 700 components and 20 projects with 2,500 credits/month. AI agent access is read-only on Pass and full access on Ultra.
• Pricing and component counts differ between pagesThe homepage states '350+ production-ready components' and 'Starting at $9.9 per month, billed annually,' while the pricing page shows Atheros AI Pass at $15/month billed annually and Atheros AI Ultra at $39/month billed annually, and references '300+ production-ready components.' Verify current figures before purchase.

Ship production-ready UI components with AI agents

Connect Claude Code, Cursor, or Codex to the Atheros MCP and let your agent search 350+ production-ready components with search_components, then write the matching template directly into your project. Component context and your design system are applied automatically, and dependencies are pinned as real files — no AI slop.

Build and reuse a private component library

Generate a whole private component library against your own design system, then pull it back into any project with get_component — the same way you reach for a catalogue template. Organize work in projects (up to 4 on Atheros AI Pass, up to 20 on AI Ultra) and keep every component on-brand.

Validate output against your design system

Run validate_project to execute automated tests and check generated output against your design system. Builder.md guidelines keep every component in line with the rest of your project, so what ships matches the design intent rather than drifting from it.

Hand off real Figma layers to designers

Copy any component in the builder and paste it into the Atheros Figma plugin. It lands as real Figma layers — auto-layout, text, and styling intact — with named layers, hug and fill sizing, and colors, gradients, shadows, corner radii, and typography carried across. Export every breakpoint or just the current view, so designers work from what was actually built.
