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.

Features

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

Installation

pip install oceanbase-mcp-server

Configuration

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

Usage

With Claude Desktop

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"
      }
    }
  }
}

As a standalone server

# Install dependencies
pip install -r requirements.txt

# Run the server
python -m oceanbase_mcp_server

Development

# Clone the repository
git clone https://github.com/yourusername/oceanbase_mcp_server.git
cd oceanbase_mcp_server

# 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 implementing query whitelisting for production use
Monitor and log all database operations

Security Best Practices

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

Create a dedicated OceanBase user with minimal permissions
Never use root credentials or administrative accounts
Restrict database access to only necessary operations
Enable logging for audit purposes
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.
