This MCP (Model Context Protocol) server provides database access capabilities to Claude, supporting SQLite, SQL Server, and PostgreSQL databases.

1. Clone the repository:

git clone https://github.com/executeautomation/database-server.git
cd database-server

2. Install dependencies:

npm install

3. Build the project:

npm run build

There are two ways to use this MCP server with Claude:

1. Direct usage: Install the package globally and use it directly
2. Local development: Run from your local development environment

The easiest way to use this MCP server is by installing it globally:

npm install -g @executeautomation/database-server

This allows you to use the server directly without building it locally.

If you want to modify the code or run from your local environment:

1. Clone and build the repository as shown in the Installation section
2. Run the server using the commands in the Usage section below

To use with an SQLite database:

node dist/src/index.js /path/to/your/database.db

To use with a SQL Server database:

node dist/src/index.js --sqlserver --server <server-name> --database <database-name> [--user <username> --password <password>]

Required parameters:

• --server: SQL Server host name or IP address
• --database: Name of the database

Optional parameters:

• --user: Username for SQL Server authentication (if not provided, Windows Authentication will be used)
• --password: Password for SQL Server authentication
• --port: Port number (default: 1433)

To use with a PostgreSQL database:

node dist/src/index.js --postgresql --host <host-name> --database <database-name> [--user <username> --password <password>]

Required parameters:

• --host: PostgreSQL host name or IP address
• --database: Name of the database

Optional parameters:

• --user: Username for PostgreSQL authentication
• --password: Password for PostgreSQL authentication
• --port: Port number (default: 5432)
• --ssl: Enable SSL connection (true/false)
• --connection-timeout: Connection timeout in milliseconds (default: 30000)

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"
      ]
    },
    "postgresql": {
      "command": "npx",
      "args": [
        "-y",
        "@executeautomation/database-server",
        "--postgresql",
        "--host", "your-host-name",
        "--database", "your-database-name",
        "--user", "your-username",
        "--password", "your-password"
      ]
    }
  }
}

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