Query and explore OceanBase databases securely via MCP

OceanBase MCP Server gives an AI assistant controlled, structured access to an OceanBase database - listing tables as resources, reading their contents, and executing SQL queries - rather than an unrestricted database connection. It is meant to make routine database exploration and analysis safer by wrapping raw SQL access behind a narrow, logged MCP interface rather than handing an assistant an open database session.

Use it when an assistant needs to explore or query an OceanBase database safely - listing available tables, reading their data, or running SQL with proper error handling and logging. The project's own security guidance is explicit and repeated: connect with a dedicated, minimal-permission OceanBase user, never root or an administrative account, and consider query whitelisting for production use - this server enforces nothing beyond what the database user's own grants allow, so the actual safety boundary is the credentials you configure, not the server itself.

Three capabilities are described: listing available OceanBase tables as MCP resources, reading table contents, and executing SQL queries with error handling. All access goes through environment-variable credentials rather than being hardcoded, and the server logs database operations comprehensively for audit purposes, so administrators can review exactly what queries an assistant actually ran against the database over time.

pip install oceanbase-mcp-server

Configuration is via environment variables: OB_HOST, OB_PORT (default 2881), OB_USER, OB_PASSWORD, and OB_DATABASE. For Claude Desktop, register it in claude_desktop_config.json with "command": "uv", "args": ["--directory", "path/to/oceanbase_mcp_server", "run", "oceanbase_mcp_server"] and the same five environment variables in the env block. It can also run standalone with python -m oceanbase_mcp_server after pip install -r requirements.txt. For development, clone the repository, create a virtual environment with python -m venv venv and activate it, install development dependencies with pip install -r requirements-dev.txt, and run the test suite with pytest to confirm everything is working before making changes.

Developers, DBAs, and analysts who want an assistant to explore or query an OceanBase database through a structured, auditable interface - provided the database credentials configured are properly scoped to the minimum access actually needed. The project's security documentation covers creating a restricted OceanBase user, setting appropriate permissions, monitoring access, and other best practices in more detail, and repeats the same principle throughout: never commit credentials to version control, and always follow the principle of least privilege when deciding what the configured database user is allowed to do.
