Configuration

Quick Start with Environment Variables

1. Copy the example environment file:

   cp .env.example .env
   

2. Edit .env with your ServiceNow credentials:

   SERVICENOW_INSTANCE=your-instance.service-now.com
   SERVICENOW_USERNAME=your-username
   SERVICENOW_PASSWORD=your-password
   

3. Run the server:

   servicenow-mcp
   

Advanced Configuration

The server supports multiple configuration methods with the following precedence:

1. Environment variables (highest priority)
2. config/local.json (local overrides)
3. config/default.json (base configuration)

      }
    }
  }
}

VS Code / Cursor

      "command": "servicenow-mcp",
      "args": ["--config-dir", "./config"],
      "env": {
        "SERVICENOW_INSTANCE": "your-instance.service-now.com",
        "SERVICENOW_USERNAME": "your-username",

Usage Examples

Creating an Incident

{
  "tool": "incident_create",
  "arguments": {
    "short_description": "Email server down",
    "description": "Production email server is not responding",
    "urgency": 1,
    "impact": 1,
    "assignment_group": "Email Support"
  }
}

Searching for Configuration Items

{
  "tool": "ci_search",
  "arguments": {
    "name": "*prod*",
    "class": "cmdb_ci_server",
    "operational_status": 1,
    "limit": 50
  }
}

Custom Table Query

{
  "tool": "query_table",
  "arguments": {
    "table": "u_custom_application",
    "query": "active=true^u_environment=production",
    "fields": ["name", "u_version", "u_owner"],
    "order_by": "-sys_updated_on"
  }
}

Security Considerations

• Never commit credentials to version control
• Use environment variables or secure secret management
• Implement least-privilege access for ServiceNow users
• Enable audit logging in production environments
• Consider using OAuth instead of basic auth for production

Development

Setting Up Development Environment

# Install development dependencies
pip install -e ".[dev]"

# Run tests
pytest

# Run linting
ruff check src/
black src/ --check

# Type checking
mypy src/

Running Tests

# Run all tests
pytest

# Run with coverage
pytest --cov=servicenow_mcp --cov-report=html

# Run specific test file
pytest tests/test_client.py

Troubleshooting

Common Issues

1. Authentication Failed

   • Verify credentials are correct
   • Check if user has API access permissions
   • Ensure instance URL is correct (with or without https://)

2. Connection Timeout

   • Increase timeout in configuration
   • Check network connectivity
   • Verify ServiceNow instance is accessible

3. Rate Limiting

   • Server automatically handles rate limits with retry
   • Consider reducing request frequency
   • Check ServiceNow rate limit settings

Debug Mode

Enable debug logging:

servicenow-mcp --log-level DEBUG

Or set in environment:

export MCP_LOG_LEVEL=DEBUG
