Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "ensemble": {
      "command": "npx",
      "args": [

        "ENSEMBLE_API_KEY": "your-value"
      }
    }
  }

Run this in your terminal

claude mcp add ensemble --env ENSEMBLE_API_KEY=your-value -- npx -y @hearthbyte/ensemble-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "ensemble": {
      "command": "npx",
      "args": [
        "-y",
        "@hearthbyte/ensemble-mcp"

        "ENSEMBLE_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Paste into .vscode/mcp.json in your project

{
  "servers": {

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Values you fill in

ENSEMBLE_API_KEY secret env
Ensemble Pro API key (hearthbyte.dev/ensemble/pricing). Without it only the free a11y_validate tool works.

Common questions

Is Ensemble safe?

It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: ENSEMBLE_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 27 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

What is this?

Ensemble MCP is a Model Context Protocol server that gives AI agents access to professional design tools. Generate color palettes, pair typography, create shadow systems, and export complete design tokens - all through natural conversation.

10 tools. One API. Infinite possibilities.

Tool	What it does	Its main argument
`harmony_generate_palette`	A full color system from one brand color	`color_scheme`
`duet_pair_fonts`	Heading, body and mono fonts with a type scale	`type_style`
`tempo_generate_scale`	A spacing system tuned to the type	`density`
`chord_generate_shadows`	Elevation shadows tinted by the palette	`shadow_intensity`
`cadence_generate_grid`	Responsive grid: breakpoints, columns, gutters	`density`
`riff_generate_motion`	Durations, easing curves and transition presets	`animation_style`
`bridge_generate_theme`	A complete dark mode from the light system	`color`
`pitch_audit_contrast`	Which palette pairs pass WCAG, and what to fix	`color`
`compose_export`	The whole system as CSS, JSON, Tailwind or SCSS	`formats`
`a11y_validate`	Check one color pair for accessibility (FREE, no key needed)	`foreground`, `background`

Every builder takes a brand color and an optional preferences object, so tools called separately agree with each other. Results are deterministic: the same color and preferences always give the same system.

------|--------------| | harmony_generate_palette | Generate harmonious color palettes from a single color | | duet_pair_fonts | Pair heading and body fonts that complement each other | | tempo_generate_scale | Create type scales and spacing systems | | chord_generate_shadows | Generate 5-level shadow elevation systems | | bridge_generate_theme | Auto-generate dark mode from light theme colors | | cadence_set_grid | Configure CSS Grid layouts with presets | | pitch_create_gradient | Create linear, radial, and conic gradients | | riff_set_easing | Set cubic-bezier easing curves | | compose_export | Export complete design system (CSS, Tailwind, SCSS, JSON) | | a11y_validate | Check color contrast accessibility (FREE, no key needed) |

Quick Start

Claude Desktop

Add to your claude_desktop_config.json:

"mcpServers": { "ensemble": { "command": "npx", "args": ["-y", "@hearthbyte/ensemble-mcp"], "env": { "ENSEMBLE_API_KEY": "your-api-key-here" } } } }

Cursor / Cline

"ensemble": { "command": "npx", "args": ["-y", "@hearthbyte/ensemble-mcp"], "env": { "ENSEMBLE_API_KEY": "your-api-key-here" } } }

Manual Installation

npm install -g @hearthbyte/ensemble-mcp

ensemble-mcp

Example Prompts

Once installed, try these with your AI:

"Generate a triadic color palette from #6366F1"

"Give me a classical font pairing and an airy spacing system to go with it"

"Check if #FFFFFF text on #6366F1 background is accessible"

"Build a design system from #0F766E with dramatic shadows and export it as Tailwind config"

"Audit the contrast of the palette you just made and tell me what fails"

API Key

The builders call the Ensemble API, which needs a Pro key ($4.99/month, or $39/year).

Free tool: a11y_validate - accessibility validation with no API key required.

Design Philosophy

Ensemble tools are built on these principles:

One color in, design system out - Start with a single value, get a complete system
Cross-tool sync - Colors flow to typography, typography informs spacing
Export everywhere - CSS, Tailwind, SCSS, JSON
Accessibility first - WCAG 2.1 + APCA checking built in
