🚀 Quick Start

One-Command Installation (Recommended)

Try DEMO mode first (no wallet needed):

# macOS/Linux
curl -sSL https://raw.githubusercontent.com/caiovicentino/polymarket-mcp-server/main/quickstart.sh | bash

# Or clone and run locally
git clone https://github.com/caiovicentino/polymarket-mcp-server.git
cd polymarket-mcp-server
./quickstart.sh

Full installation (with trading):

# macOS/Linux
./install.sh

# Windows
install.bat

The automated installer will:

• ✓ Check Python version (3.10+)
• ✓ Create virtual environment
• ✓ Install all dependencies
• ✓ Configure environment
• ✓ Set up Claude Desktop integration
• ✓ Test the installation

Installation Options

DEMO Mode vs Full Mode

DEMO Mode (No wallet required):

• ✅ Market discovery and search
• ✅ Real-time market analysis
• ✅ AI-powered insights
• ✅ Price monitoring
• ❌ Trading disabled (read-only)

Full Mode (Requires Polygon wallet):

• ✅ Everything in DEMO mode
• ✅ Place orders and execute trades
• ✅ Portfolio management
• ✅ Position tracking
• ✅ Real-time trade notifications

Manual Installation

If you prefer manual setup:

# Clone the repository
git clone https://github.com/caiovicentino/polymarket-mcp-server.git
cd polymarket-mcp-server

# Create virtual environment
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install the package
pip install -e .

Configuration

Option 1: DEMO Mode (easiest)

cp .env.example .env
# Edit .env and set:
DEMO_MODE=true

Option 2: Full Trading Mode

cp .env.example .env
# Edit with your Polygon wallet credentials
nano .env

Required credentials (Full Mode):

POLYGON_PRIVATE_KEY=your_private_key_without_0x_prefix
POLYGON_ADDRESS=0xYourPolygonAddress

Recommended Safety Limits:

MAX_ORDER_SIZE_USD=1000
MAX_TOTAL_EXPOSURE_USD=5000
MAX_POSITION_SIZE_PER_MARKET=2000
MIN_LIQUIDITY_REQUIRED=10000
MAX_SPREAD_TOLERANCE=0.05
ENABLE_AUTONOMOUS_TRADING=false
REQUIRE_CONFIRMATION_ABOVE_USD=500

With ENABLE_AUTONOMOUS_TRADING=false (the default), every order is held and returned as confirmation_required until you re-issue it with confirm=true. Set it to true to let orders under REQUIRE_CONFIRMATION_ABOVE_USD go through without that step.
