### Description (declared)

# Microsoft SQL Server MCP Server

A Model Context Protocol (MCP) server that enables secure interaction with Microsoft SQL Server databases. This server allows AI assistants to list tables, read data, and execute SQL queries through a controlled interface, making database exploration and analysis safer and more structured.

## Features

- List available SQL Server tables as resources
- Read table contents
- Execute SQL queries with proper error handling
- Secure database access through environment variables
- Comprehensive logging
- Automatic system dependency installation

## Installation

The package will automatically install required system dependencies (like FreeTDS) when installed through MCP:

```bash
pip install mssql-mcp
```

## Configuration

Set the following environment variables:

```bash
MSSQL_SERVER=localhost
MSSQL_USER=your_username
MSSQL_PASSWORD=your_password
MSSQL_DATABASE=your_database
```

## Usage

### With Claude Desktop

Add this to your `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "mssql": {
      "command": "uv",
      "args": [
        "--directory", 
        "path/to/mssql_mcp",
        "run",
        "mssql_mcp"
      ],
      "env": {
        "MSSQL_SERVER": "localhost",
        "MSSQL_USER": "your_username",
        "MSSQL_PASSWORD": "your_password",
        "MSSQL_DATABASE": "your_database"
      }
    }
  }
}
```

### As a standalone server

```bash
# Install dependencies
pip install -r requirements.txt

# Run the server
python -m mssql_mcp
```

## Development

```bash
# Clone the repository
git clone https://github.com/RichardHan/mssql_mcp.git
cd mssql_mcp

# Create virtual environment
python -m venv venv
source venv/bin/activate  # or `venv\Scripts\activate` on Windows

# Install development dependencies
pip install -r requirements-dev.txt

# Run tests
pytest
```

## Security Considerations

- Never commit environment variables or credentials
- Use a database user with minimal required permissions
- Consider imp…
