oceanbase_mcp_server

A Model Context Protocol (MCP) server that enables secure interaction with OceanBase 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.

• List available OceanBase tables as resources
• Read table contents
• Execute SQL queries with proper error handling
• Secure database access through environment variables
• Comprehensive logging

pip install oceanbase-mcp-server

Set the following environment variables:

OB_HOST=localhost     # Database host
OB_PORT=2881         # Optional: Database port (defaults to 2881 if not specified)
OB_USER=your_username
OB_PASSWORD=your_password
OB_DATABASE=your_database

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "oceanbase": {
      "command": "uv",
      "args": [
        "--directory", 
        "path/to/oceanbase_mcp_server",
        "run",
        "oceanbase_mcp_server"
      ],
      "env": {
        "OB_HOST": "localhost",
        "OB_PORT": "2881",
        "OB_USER": "your_username",
        "OB_PASSWORD": "your_password",
        "OB_DATABASE": "your_database"
      }
    }
  }

• Never commit environment variables or credentials
• Use a database user with minimal required permissions
• Consider implementing query whitelisting for production use
• Monitor and log all database operations

This MCP server requires database access to function. For security:

1. Create a dedicated OceanBase user with minimal permissions
2. Never use root credentials or administrative accounts
3. Restrict database access to only necessary operations
4. Enable logging for audit purposes
5. Regular security reviews of database access

See OceanBase Security Configuration Guide for detailed instructions on:

• Creating a restricted OceanBase user
• Setting appropriate permissions
• Monitoring database access
• Security best practices

⚠️ IMPORTANT: Always follow the principle of least privilege when configuring database access.
