🔧 Configuration

Environment Variables

Copy .env.example to .env and customize:

# WebSim API Configuration
WEBSIM_API_BASE_URL=https://api.websim.com
WEBSIM_API_TIMEOUT=30000

# Server Configuration
MCP_SERVER_NAME=websim-mcp-server
MCP_SERVER_VERSION=1.0.0

# Logging
LOG_LEVEL=info
LOG_FORMAT=json

Custom API Base URL

If WebSim provides a different API endpoint, update the configuration:

// In server.js, modify the WEBSIM_API_BASE constant
const WEBSIM_API_BASE = 'https://your-custom-api-endpoint.com';

🏥 Health Monitoring

The server includes a built-in health check system:

// Health check tool call
{
  "tool": "health_check",
  "arguments": {}
}

This checks:
