Penpot MCP Server 🎨🤖

🚀 What is Penpot MCP?

Penpot MCP is a revolutionary Model Context Protocol (MCP) server that bridges the gap between AI language models and Penpot, the open-source design and prototyping platform. This integration enables AI assistants like Claude (in both Claude Desktop and Cursor IDE) to understand, analyze, and interact with your design files programmatically.

🎯 Key Benefits

• 🤖 AI-Native Design Analysis: Let Claude AI analyze your UI/UX designs, provide feedback, and suggest improvements
• ⚡ Automated Design Workflows: Streamline repetitive design tasks with AI-powered automation
• 🔍 Intelligent Design Search: Find design components and patterns across your projects using natural language
• 📊 Design System Management: Automatically document and maintain design systems with AI assistance
• 🎨 Cross-Platform Integration: Works with any MCP-compatible AI assistant (Claude Desktop, Cursor IDE, etc.)

🚀 Quick Start

Prerequisites

• Python 3.12+ (Latest Python recommended for optimal performance)
• Penpot Account (Sign up free)
• Claude Desktop or Cursor IDE (Optional, for AI integration)

Installation

Prerequisites

• Python 3.12+
• Penpot account credentials

Installation

Option 1: Install from PyPI

pip install penpot-mcp

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

# 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

# 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
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

# 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:

# 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:

# 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
