conductor-figma

Design-intelligent MCP server for Figma. 201 tools across 17 categories. Every tool has built-in design intelligence — 8px grid, type scales, semantic colors, accessibility checks, component defaults. Works with Cursor and Claude Code.

npx conductor-figma

How to use

1. Clone the repo (for the Figma plugin)

git clone https://github.com/dragoon0x/conductor.git

2. Import the Figma plugin

Open Figma Desktop:

1. Go to Plugins → Development → Import plugin from manifest
2. Navigate to conductor/figma-plugin/manifest.json
3. Click Open

The plugin is now installed. You only need to do this once.

3. Add to Cursor

Open ~/.cursor/mcp.json and add conductor:

{
  "mcpServers": {
    "conductor": {
      "command": "npx",
      "args": ["-y", "conductor-figma"]
    }
  }
}

Restart Cursor.

4. Connect and design

1. Open a Figma file
2. Run the plugin: Plugins → Development → Conductor
3. The plugin should show a green dot (Connected)
4. In Cursor chat, type @conductor followed by any command

Example prompts

@conductor Create a dark hero section with a big heading and a purple CTA button

@conductor Check contrast between #ffffff and #6366f1

@conductor Create a dashboard layout with sidebar, KPI cards, and chart area

@conductor Audit accessibility on my current selection

@conductor Replace all #6366f1 with #3b82f6 across the file

@conductor Export this frame as React + Tailwind code

@conductor Scan my file and show me all off-grid spacing

@conductor Generate a color palette from #6366f1

Alternative: use local path (faster startup)

Instead of npx, point directly to the cloned repo:

{
  "mcpServers": {
    "conductor": {
      "command": "node",
      "args": ["/path/to/conductor/bin/conductor.js"]
    }
  }
}

How it works

You type in Cursor → MCP server (stdio) → WebSocket :3055 → Figma plugin → Canvas

Cursor starts the MCP server automatically. The server opens a WebSocket on port 3055. The Figma plugin connects to that WebSocket and executes commands on the canvas.

What makes this different

Other MCP servers for Figma are API wrappers. You give exact pixel values, they obey — even when those values are wrong. Conductor applies design rules before anything touches the canvas.

You say "create a button." A typical MCP makes a rectangle. Conductor makes a 44px-tall frame with 20px horizontal padding, 10px radius, 15px Semi Bold text — because that's what a button actually is.

Design intelligence engine

Every tool queries the intelligence engine before touching Figma:

• 8px Grid — All spacing values snapped. snap(13) = 16.
• Type Scale — 7 ratio presets: Minor Second through Golden Ratio.
• Semantic Colors — Full palette from one brand hex. Dark + light modes.
• Component Defaults — 18 component types with size variants.
• Accessibility — WCAG AA/AAA contrast, 44px touch targets, font minimums.
• Font Weights — Auto-resolves "bold" → "Bold", "600" → "Semi Bold".
• Layout Intelligence — 13 layout presets: row, column, center, spread, sidebar, grid, form.

Troubleshooting

Plugin says "Disconnected" The MCP server isn't running. Make sure Cursor is open and conductor is configured in mcp.json. Try sending any @conductor message in Cursor chat — that triggers the server to start.

Port 3055 already in use Kill the old process: kill $(lsof -t -i :3055) 2>/dev/null then restart Cursor.

Cursor shows "Loading tools" forever Make sure you have the latest version. Run: npx conductor-figma@latest Or use the local path method for faster startup.
