📦 Quick Start

✅ Prerequisites

# Required
Node.js >= 18.0.0
npm >= 9.0.0

# Casper Network API Key from cspr.cloud
# Get your free API key at: https://cspr.cloud

🔑 Configuration

Create a .env file with your Casper Network configuration:

• CASPER_API_KEY: Your API key from cspr.cloud (required)
• CASPER_RPC_URL: RPC endpoint (default: https://node.cspr.cloud/rpc)
• CASPER_NETWORK_NAME: Network name (default: casper for mainnet)
• PORT: HTTP server port (default: 8080)
• CASPER_PRIVATE_KEY: Optional default wallet private key (PEM format)
• CASPER_PUBLIC_KEY: Optional default wallet public key

📥 Installation

# Clone the repository
git clone https://github.com/Tairon-ai/casper-network-mcp.git
cd casper-network-mcp

# Install dependencies
npm install

# Configure environment
cp .env.example .env
# Edit .env and add your CASPER_API_KEY from cspr.cloud

# Start the HTTP server
npm start

# MCP stdio server for Claude Desktop
npm run mcp

🤖 Claude Desktop Integration

Add to your Claude Desktop configuration:

{
  "mcpServers": {
    "casper-network": {
      "command": "node",
      "args": ["/path/to/casper-network-mcp/mcp/index.js"],
      "env": {
        "CASPER_API_KEY": "your_api_key_from_cspr_cloud",
        "CASPER_RPC_URL": "https://node.cspr.cloud/rpc",
        "CASPER_NETWORK_NAME": "casper"
      }
    }
  }
}

Note: Get your API key from https://cspr.cloud for mainnet access

🔒 Security

🛡️ Security Best Practices

• Private Key Protection - Never commit .env files or private keys to version control
• Environment Variables - Store sensitive data (API keys, private keys) in environment variables
• API Key Security - Keep your cspr.cloud API key secure and don't share it
• Input Validation - All public keys and amounts are validated before processing
• Mainnet Caution - This server operates on Casper mainnet with real CSPR tokens
• Error Handling - Errors don't expose sensitive wallet information
• Secure Communication - All RPC calls use HTTPS to cspr.cloud
