MCP Integration

For MCP client applications, configure your client to connect to this server:

{
  \"mcpServers\": {
    \"sgp\": {
      \"command\": \"node\",
      \"args\": [\"/path/to/sgp-mcp-server/dist/index.js\"],
      \"env\": {
        \"SGP_BASE_URL\": \"https://demo.sgp.net.br/api\",
        \"SGP_API_TOKEN\": \"your_token\"
      }
    }
  }
}

Authentication Methods

1. Basic Authentication

Uses username and password for SGP admin access:

SGP_USERNAME=admin_user
SGP_PASSWORD=admin_password

2. Token Authentication

Uses API token for enhanced security:

SGP_API_TOKEN=your_api_token
SGP_APP_NAME=your_app_name

3. CPF/CNPJ Authentication

For customer portal access (passed in function calls):

{
  \"cpfcnpj\": \"12345678900\",
  \"senha\": \"customer_password\"
}

Rate Limits

  • Basic Auth: 100 requests/minute
  • Token Auth: 300 requests/minute
  • CPF/CNPJ Auth: 50 requests/minute

Caching

The server implements intelligent caching:

  • Default TTL: 5 minutes
  • Max Keys: 1000
  • Cache Keys: Automatically generated based on endpoint and parameters

Error Handling

  • Automatic retry with exponential backoff
  • Comprehensive error logging
  • Graceful degradation for rate limits
  • Clear error messages in API responses

Architecture & Implementation

Technical Specifications

  • Total Methods: 327+ API methods implemented
  • MCP Tools: 219+ tools across all business systems
  • Code Coverage: ~95% of SGP API functionality
