Configuring Claude Desktop

Direct Usage Configuration

If you installed the package globally, configure Claude Desktop with:

{
  "mcpServers": {
    "sqlite": {
      "command": "npx",
      "args": [
        "-y",
        "@executeautomation/database-server",
        "/path/to/your/database.db"
      ]
    },
    "sqlserver": {
      "command": "npx",
      "args": [
        "-y",
        "@executeautomation/database-server",
        "--sqlserver",
        "--server", "your-server-name",
        "--database", "your-database-name",
        "--user", "your-username",
        "--password", "your-password"
      ]
    }
  }
}

Local Development Configuration

For local development, configure Claude Desktop to use your locally built version:

{
  "mcpServers": {
    "sqlite": {
      "command": "node",
      "args": [
        "/absolute/path/to/mcp-database-server/dist/src/index.js", 
        "/path/to/your/database.db"
      ]
    },
    "sqlserver": {
      "command": "node",
      "args": [
        "/absolute/path/to/mcp-database-server/dist/src/index.js",
        "--sqlserver",
        "--server", "your-server-name",
        "--database", "your-database-name",
        "--user", "your-username",
        "--password", "your-password"
      ]
    }
  }
}

The Claude Desktop configuration file is typically located at:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json
