Superdesign MCP Server
# Superdesign MCP Server
An MCP (Model Context Protocol) server that brings [Superdesign](https://github.com/superdesigndev/superdesign) - an open source AI design agent by [@jasonzhou1993](https://twitter.com/jasonzhou1993) and [@jackjack_eth](https://twitter.com/jackjack_eth) - to Claude Code as native tools. This server operates as a "design orchestrator" that provides structured specifications for your IDE's LLM to execute, enabling Superdesign's sophisticated design capabilities without requiring Anthropic API keys.
## Key Benefits
- **No API Keys Required**: Works directly with Claude Code's built-in LLM connection
- **Local Execution**: Runs entirely on your machine as an MCP server
- **IDE Integration**: Seamlessly integrates with Claude Code (and potentially Cursor, Windsurf, or other MCP-compatible IDEs - untested)
- **Based on Open Source**: Built on top of [Superdesign.dev](https://www.superdesign.dev), an open source AI design system
## Installation
1. Install dependencies:
```bash
npm install
```
2. Build the server:
```bash
npm run build
```
## Claude Code Integration
1. Add the MCP server to your Claude Code configuration:
```bash
# Create or edit your Claude Code MCP settings file
# On macOS:
mkdir -p ~/.claude-code
cp claude-mcp-config.json ~/.claude-code/mcp-settings.json
# Or add manually to your existing mcp-settings.json:
```
Example `~/.claude-code/mcp-settings.json`:
```json
{
"mcpServers": {
"superdesign": {
"command": "node",
"args": ["/path/to/superdesign/dist/index.js"],
"env": {}
}
}
}
```
2. Restart Claude Code
3. The MCP server will provide these Superdesign orchestrator tools in Claude Code:
- `superdesign_generate` - Returns specifications for Claude to generate designs
- `superdesign_iterate` - Returns instructions for Claude to iterate on existing designs
- `superdesign_extract_system` - Returns instructions for design system extraction
- `superdesign_list` - Lists all created designs in the workspace
## Development
Run in development mode:
```bash
npm run dev
```

**Output**: Gallery HTML file with embedded previews and JavaScript interactions. The gallery opens automatically in your browser, providing a Superdesign-like canvas experience.
## How the Orchestrator Works
This MCP server operates as a **design orchestrator** rather than a direct generator:
1. **User Request**: "Generate a modern dashboard UI"
2. **MCP Server**: Returns detailed specifications with:
- Complete Superdesign system prompt and guidelines
- Exact file paths and naming conventions
- Design type-specific instructions
- Number of variations to create
3. **Claude Code**: Receives specifications and:
- Generates the actual HTML/SVG/React code
- Saves files to specified locations
- Follows all Superdesign design principles
## Usage in Claude Code
Once configured, you can use Superdesign through Claude Code with natural language:
**Example Usage:**
- "Generate a modern dashboard UI design"
- "Create 3 variations of a login page wireframe"
- "Design a React component for a product card"
- "Make a minimalist logo for a tech startup"
- "Iterate on the dashboard design with better spacing"
- "Show me the gallery of all my designs"
**Requirements:**
- Claude Code with MCP support
- No API keys needed (uses Claude Code's existing LLM connection)
**File Organization:**
Designs are automatically saved to `superdesign/` directory (visible folder):
- `design_iterations/` - Generated designs (HTML/SVG files)
- `design_system/` - Extracted design systems (JSON files)
**Benefits:**
- No API key configuration required
- Uses Claude Code's existing LLM capabilities
- Maintains all of Superdesign's sophisticated design methodology
- Proper file organization and naming conventions
- Full design iteration workflow support
## Known Issues & Troubleshooting
### File Permissions Error
If you encounter permission errors when running the MCP server:
```bash
# Add execute permissions to the built file
chmod +x dist/index.js
```
### MCP Tools Not Appearing
If Superdesign tools don't appear in Claude Code after installation:
1. Ensure you've completely quit Claude Code (not just closed the window)
2. Restart Claude Code from your terminal
3. Verify the server is registered: `claude mcp list`
4. Check the tools are available by asking Claude: "What tools do you have available?"
### Server Registration Issues
If the server fails to register:
```bash
# Remove and re-add the server
claude mcp remove superdesign -s user
claude mcp add --scope user superdesign /path/to/superdesign/dist/index.js
```
### Build Errors
Ensure you have Node.js 16+ installed:
```bash
node --version # Should be v16.0.0 or higher
```
## 🤝 Relationship to Superdesign
This MCP server provides a complementary integration for [Superdesign](https://github.com/superdesigndev/superdesign) by [@jasonzhou1993](https://twitter.com/jasonzhou1993) and [@jackjack_eth](https://twitter.com/jackjack_eth).
While Superdesign offers an IDE extension that works across multiple editors, this MCP server specifically enhances Claude Code by:
- **Eliminating the need for API keys** - uses Claude Code's built-in LLM connection
- **Providing native tool integration** - no manual prompt copying required
- **Enabling direct tool calls** - seamless workflow without copy/paste
This addresses the community request for Claude Code API provider support (see [Superdesign Issue #3](https://github.com/superdesigndev/superdesign/issues)).
### How it's Different
| Aspect | Superdesign Extension | This MCP Server |
|--------|----------------------|-----------------|
| **Integration Type** | IDE Extension | Native MCP Tools |
| **Claude Code Access** | Manual prompt copying | Direct tool invocation |
| **API Requirements** | Separate API key needed | Uses Claude Code's existing connection |
| **User Experience** | Copy/paste workflow | Automated orchestration |

TDQS
Scored across 9 tools
Each tool has a clearly distinct purpose with no ambiguity: checking files, cleaning up, deleting, extracting systems, generating galleries, generating designs, iterating, listing, and live galleries. The descriptions clearly differentiate their functions, such as 'superdesign_generate' for creating designs versus 'superdesign_iterate' for refining them, preventing misselection.
All tool names follow a consistent 'superdesign_' prefix with a descriptive verb_noun pattern (e.g., superdesign_check_files, superdesign_generate). There are no deviations in style or convention, making the naming predictable and easy to understand across the set.
With 9 tools, the count is well-scoped for a design-focused server, covering key operations like creation, iteration, listing, and cleanup. Each tool earns its place by addressing specific aspects of the design workflow, avoiding bloat or thin coverage.
The tool set provides comprehensive coverage for design workflows, including create (generate), read (list, gallery), update (iterate), and delete (delete, cleanup), with additional utilities like file checking and live galleries. A minor gap exists in direct update or metadata management tools, but agents can work around this using iteration and deletion.
