Kura UI
v0.0.0 · 35 components · agent-ready

Interfaces for working with machines.

Kura UI is an open-source React toolkit of AI-native surfaces — composers, voice, shaders and agent harnesses — quiet by default, alive when the model speaks. Built so your coding agent picks the right component, every time.

Agents are the primary users

Discoverable, explainable, installable — by a model.

Every component ships a typed manifest. The docs, the shadcn registry, llms.txt, the MCP server and the CLI are all generated from it, so they can never disagree.

Agent integration guide

A manifest per component

whenToUse, whenNotToUse, props with JSON Schema, anatomy, a11y and examples — validated against the TypeScript source on every commit.

MCP server

search_components, get_component, get_install_instructions, get_design_tokens. Your agent asks; Kura answers with exactly what to install.

llms.txt + markdown

Every docs page has a raw .md twin. llms-full.txt carries the whole library in one fetch.

CLI with --json

kura search, kura add, kura doctor. Copies source plus dependencies, shadcn-compatible, machine-readable output.

Components

Live, not screenshots. Each one reads its own manifest.

Voice agent idle

Agent Orb

voice

Glassy liquid sphere for voice agents, drawn in a shader: breathes when idle, reacts to mic and voice levels, swirls while thinking.

Composer

input

Prompt input for chat and agents: auto-growing textarea, attachments, toolbar slot, send→stop button, paste/drop files and a length hint.

  1. Read the failing test (done)1.2s
  2. Patch the date parser (in progress)
  3. Re-run the test suite (queued)
Step 2 of 3

Agent Timeline

agent

Vertical plan tracker for multi-step agents: queued/active/done/failed/skipped steps, nested sub-steps, live durations and a connector that fills.

Artifact Card

conversation

Card for something an agent made — document, code, web page, image, sheet or diagram — with generating/updating progress, versions and open-in-panel.

Audio Waveform

voice

Canvas audio visualiser — live bars, mirrored history or oscilloscope line from a mic or media element, or recorded peaks with a seek scrubber.

Mesh Gradient

effects

Animated WebGL mesh gradient that blends up to six colours in OKLab, with distortion, swirl, grain and a pointer lens — for heroes and empty states.

Ask your agent

Add the MCP server and describe what you need. The agent searches the catalog, reads the manifest, and installs the component with its dependencies and tokens.
