Kala Mcp

Kala (कला)

An MCP server that helps coding agents build production-grade frontend — work that reads as though an experienced designer made it, rather than a template filled in.

It does four things a coding agent cannot do reliably on its own:

It works across React, Vue, Svelte, and plain HTML — one rule, written once, fires identically in all four — and can render a running page to catch what source analysis structurally cannot.

Install

Claude Code — the plugin carries the server, the companion skill, the /kala command, and the restricted subagent in one install:

/plugin marketplace add archish9/Kala
/plugin install kala@kala-marketplace

Antigravity (agy) — one command installs the server, the companion skill, and the /kala rule:

agy plugin install https://github.com/archish9/Kala

Restart your IDE, then type /kala followed by your request.

Any other MCP client — one block of JSON, no clone and no build:

{
  "mcpServers": {
    "kala": {
      "command": "npx",
      "args": ["-y", "-p", "kala-mcp", "-p", "playwright", "kala-mcp"]
    }
  }
}

Node 20+ is the only requirement. Open your agent in a project and say:

"What design system does this project have?"

Per-client config, building from source, and the companion skill: Install. Complete walkthrough: Your first project.

What you can ask for

There are no commands to memorise — you talk to your agent normally.

Thirteen design actions are available by name: bolder, quieter, distill, harden, animate, typeset, layout, colorize, delight, clarify, adapt, optimize, onboard.

More phrasings for every task: What to say.

What ships today

• 8 MCP tools — system_status, system_bootstrap, surface_brief, guide, verify, inspect, critique, explain
• 13 source rules across scale, consistency, accessibility, craft, and real-world states
• 3 rendered checks — computed contrast, horizontal overflow, touch target size
• 12 curated design systems with generated OKLCH palettes and solved contrast, backed by a catalog of 84 styles, 192 palettes, and 74 typography pairings for briefs none of the 12 fit well
• 6 surface briefs and 13 action playbooks
• 4 framework extractors proven equivalent by a dedicated test suite
• 492 tests, typechecked under strict and exactOptionalPropertyTypes
• No browser required — the rendered pass is opt-in and degrades cleanly
• No network calls, no API keys — static data plus deterministic code; nothing kala does depends on an external service
