Quick Start

Install with Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "mssql": {
      "command": "uvx",
      "args": ["microsoft_sql_server_mcp"],
      "env": {
        "MSSQL_SERVER": "localhost",
        "MSSQL_DATABASE": "your_database",
        "MSSQL_USER": "your_username",
        "MSSQL_PASSWORD": "your_password"
      }
    }
  }
}

Configuration

Basic SQL Authentication

MSSQL_SERVER=localhost          # Required
MSSQL_DATABASE=your_database    # Required
MSSQL_USER=your_username        # Required for SQL auth
MSSQL_PASSWORD=your_password    # Required for SQL auth

Windows Authentication

MSSQL_SERVER=localhost
MSSQL_DATABASE=your_database
MSSQL_WINDOWS_AUTH=true         # Use Windows credentials

Azure SQL Database

MSSQL_SERVER=your-server.database.windows.net
MSSQL_DATABASE=your_database
MSSQL_USER=your_username
MSSQL_PASSWORD=your_password
# Encryption is automatic for Azure

Optional Settings

MSSQL_PORT=1433                 # Custom port (default: 1433)
MSSQL_ENCRYPT=true              # Force encryption

Alternative Installation Methods

Using pip

pip install microsoft_sql_server_mcp

Then in claude_desktop_config.json:

{
  "mcpServers": {
    "mssql": {
      "command": "python",
      "args": ["-m", "mssql_mcp_server"],
      "env": { ... }
    }
  }
}

Development

git clone https://github.com/RichardHan/mssql_mcp_server.git
cd mssql_mcp_server
pip install -e .

Security

• Create a dedicated SQL user with minimal permissions
• Never use admin/sa accounts
• Use Windows Authentication when possible
• Enable encryption for sensitive data
