Quick Setup

Configure Claude Desktop

Configuration File Location:

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

Basic Configuration:

{
  "mcpServers": {
    "rbdc-mcp": {
      "command": "rbdc-mcp",
      "args": ["--database-url", "sqlite://./database.db"]
    }
  }
}

Database Connection Examples

SQLite:

{
  "mcpServers": {
    "rbdc-mcp-sqlite": {
      "command": "rbdc-mcp",
      "args": ["--database-url", "sqlite://./database.db"]
    }
  }
}

MySQL:

{
  "mcpServers": {
    "rbdc-mcp-mysql": {
      "command": "rbdc-mcp",
      "args": ["--database-url", "mysql://user:password@localhost:3306/database"]
    }
  }
}

PostgreSQL:

{
  "mcpServers": {
    "rbdc-mcp-postgres": {
      "command": "rbdc-mcp",
      "args": ["--database-url", "postgres://user:password@localhost:5432/database"]
    }
  }
}

Windows Full Path (if not in PATH):

{
  "mcpServers": {
    "rbdc-mcp": {
      "command": "C:\\tools\\rbdc-mcp.exe",
      "args": ["--database-url", "sqlite://C:\\path\\to\\database.db"]
    }
  }
}

After Configuration

1. Save the configuration file
2. Restart Claude Desktop to load the MCP server
3. Test the connection with queries like:
   • "Show me the database connection status"
   • "What tables are in my database?"

Usage Examples

Natural Language Database Operations

You can interact with your database using natural language queries in Claude:

• Query Data: "Show me all users in the database"
• Modify Data: "Add a new user named John with email [email protected]"
• Get Status: "What's the database connection status?"
• Schema Info: "What tables exist in my database?"

Supported Databases

Database	Connection URL Format
SQLite	sqlite://path/to/database.db
MySQL	mysql://user:password@host:port/database
PostgreSQL	postgres://user:password@host:port/database
MSSQL	mssql://user:password@host:port/database

Configuration Options

Parameter	Description	Default
--database-url, -d	Database connection URL	Required
--max-connections	Maximum connection pool size	1
--timeout	Connection timeout (seconds)	30
--log-level	Log level (error/warn/info/debug)	info

Available Tools

• sql_query: Execute SELECT queries safely
• sql_exec: Execute INSERT/UPDATE/DELETE operations
• db_status: Check connection pool status

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "rbdc-mcp" '{"command":"rbdc-mcp","args":["--database-url","sqlite://./database.db"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "rbdc-mcp": {
            "command": "rbdc-mcp",
            "args": [
                "--database-url",
                "sqlite://./database.db"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

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

2. Add this to your configuration file:

{
    "mcpServers": {
        "rbdc-mcp": {
            "command": "rbdc-mcp",
            "args": [
                "--database-url",
                "sqlite://./database.db"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
