### Installation

#### Option 1: Install from PyPI

```bash
pip install penpot-mcp
```

#### Option 2: Using uv (recommended for modern Python development)

```bash
# Install directly with uvx (when published to PyPI)
uvx penpot-mcp

# For local development, use uvx with local path
uvx --from . penpot-mcp

# Or install in a project with uv
uv add penpot-mcp
```

#### Option 3: Install from source

```bash
# Clone the repository
git clone https://github.com/montevive/penpot-mcp.git
cd penpot-mcp

# Using uv (recommended)
uv sync
uv run penpot-mcp

# Or using traditional pip
python -m venv .venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate
pip install -e .
```

### Configuration

Create a `.env` file based on `env.example` with your Penpot credentials:

```
PENPOT_API_URL=https://design.penpot.app/api
PENPOT_USERNAME=your_penpot_username
PENPOT_PASSWORD=your_penpot_password
PORT=5000
DEBUG=true
```

> **⚠️ CloudFlare Protection Notice**: The Penpot cloud site (penpot.app) uses CloudFlare protection that may occasionally block API requests. If you encounter authentication errors or blocked requests:
> 1. Open your web browser and navigate to [https://design.penpot.app](https://design.penpot.app)
> 2. Log in to your Penpot account
> 3. Complete any CloudFlare human verification challenges if prompted
> 4. Once verified, the API requests should work normally for a period of time

## Usage

### Running the MCP Server

```bash
# Using uvx (when published to PyPI)
uvx penpot-mcp

# Using uvx for local development
uvx --from . penpot-mcp

# Using uv in a project (recommended for local development)
uv run penpot-mcp

# Using the entry point (if installed)
penpot-mcp

# Or using the module directly
python -m penpot_mcp.server.mcp_server
```

### Debugging the MCP Server

To debug the MCP server, you can:

1. Enable debug mode in your `.env` file by setting `DEBUG=true`
2. Use the Penpot API CLI for testing API operations:

```bash
# Test API connection with debug output
python -m penpot_mcp.api.penpot_api --debug list-projects

# Get details for a specific project
python -m penpot_mcp.api.penpot_api --debug get-project --id YOUR_PROJECT_ID

# List files in a project
python -m penpot_mcp.api.penpot_api --debug list-files --project-id YOUR_PROJECT_ID

# Get file details
python -m penpot_mcp.api.penpot_api --debug get-file --file-id YOUR_FILE_ID
```

### Command-line Tools

The package includes utility command-line tools:

```bash
# Generate a tree visualization of a Penpot file
penpot-tree path/to/penpot_file.json

# Validate a Penpot file against the schema
penpot-validate path/to/penpot_file.json
```

### MCP Monitoring & Testing

#### MCP CLI Monitor

```bash
# Start your MCP server in one terminal
python -m penpot_mcp.server.mcp_server

# In another terminal, use mcp-cli to monitor and interact with your server
python -m mcp.cli monitor python -m penpot_mcp.server.mcp_server

# Or connect to an already running server on a specific port
python -m mcp.cli monitor --port 5000
```

#### MCP Inspector

```bash
# Start your MCP server in one terminal
python -m penpot_mcp.server.mcp_server

# In another terminal, run the MCP Inspector (requires Node.js)

## AI Integration

The Penpot MCP server can be integrated with AI assistants using the Model Context Protocol. It supports both Claude Desktop and Cursor IDE for seamless design workflow automation.

### Claude Desktop Integration

For detailed Claude Desktop setup instructions, see [CLAUDE_INTEGRATION.md](CLAUDE_INTEGRATION.md).

Add the following configuration to your Claude Desktop config file (`~/Library/Application Support/Claude/claude_desktop_config.json` on macOS or `%APPDATA%\Claude\claude_desktop_config.json` on Windows):

```json
{
  "mcpServers": {
    "penpot": {
      "command": "uvx",
      "args": ["penpot-mcp"],
      "env": {
        "PENPOT_API_URL": "https://design.penpot.app/api",
        "PENPOT_USERNAME": "your_penpot_username",
        "PENPOT_PASSWORD": "your_penpot_password"
      }
    }
  }
}
```

### Cursor IDE Integration

Cursor IDE supports MCP servers through its AI integration features. To configure Penpot MCP with Cursor:

1. **Install the MCP server** (if not already installed):
   ```bash
   pip install penpot-mcp
   ```

2. **Configure Cursor settings** by adding the MCP server to your Cursor configuration. Open Cursor settings and add:

   ```json
   {
     "mcpServers": {
       "penpot": {
         "command": "uvx",
         "args": ["penpot-mcp"],
         "env": {
           "PENPOT_API_URL": "https://design.penpot.app/api",
           "PENPOT_USERNAME": "your_penpot_username",
           "PENPOT_PASSWORD": "your_penpot_password"
         }
       }
     }
   }
   ```

3. **Alternative: Use environment variables** by creating a `.env` file in your project root:
   ```bash
   PENPOT_API_URL=https://design.penpot.app/api
   PENPOT_USERNAME=your_penpot_username
   PENPOT_PASSWORD=your_penpot_password
   ```

4. **Start the MCP server** in your project:
   ```bash
   # In your project directory
   penpot-mcp
   ```

5. **Use in Cursor**: Once configured, you can interact with your Penpot designs directly in Cursor by asking questions like:
   - "Show me all projects in my Penpot account"
   - "Analyze the design components in project X"
   - "Export the main button component as an image"
   - "What design patterns are used in this file?"

### Key Integration Features

Both Claude Desktop and Cursor integration provide:
- **Direct access** to Penpot projects and files
- **Visual component analysis** with AI-powered insights
- **Design export capabilities** for assets and components
- **Natural language queries** about your design files
- **Real-time design feedback** and suggestions
- **Design system documentation** generation
