DBHub MCP란?
DBHub은(는) MCP server입니다. Connects AI clients to PostgreSQL, MySQL, SQL Server, Oracle, MariaDB, and SQLite to explore schemas and execute SQL queries.
프로젝트 README에서 생성된 요약
DBHub MCP server 정보
Connecting AI clients to diverse database systems is what DBHub enables for developers using tools like Claude Desktop, Cursor, or VS Code. This lightweight gateway provides a single interface to interact with PostgreSQL, MySQL, MariaDB, SQL Server, Oracle, and SQLite. By using a minimal set of tools, it preserves the context window of your AI client, consuming only 1.4k tokens by default.
Users can configure multiple simultaneous connections through a TOML file and manage access via SSH tunneling or SSL/TLS encryption. The server includes safety features such as read-only mode, row limiting, and query timeouts to prevent accidental or runaway operations. Beyond the standard execute_sql and search_objects tools, users can opt-in to explain_sql and health_check or define their own parameterized operations. It is designed to be a zero-dependency solution that works locally via npx or through Docker containers.

MCP Clients MCP Server Databases
DBHub is a minimal MCP server: token-efficient, zero-dependency, and just two tools by default with opt-in extras. This lightweight gateway allows MCP-compatible clients to connect to and explore different databases:
- Minimal: Zero dependency, token efficient with a minimal set of MCP tools to maximize context window
- Multi-Database: PostgreSQL, MySQL, MariaDB, SQL Server, Oracle, and SQLite through a single interface
- Multi-Connection: Connect to multiple databases simultaneously with TOML configuration
- Guardrails: Read-only mode, row limiting, and query timeout to prevent runaway operations
- Secure Access: SSH tunneling and SSL/TLS encryption
DBHub is the official example in the Claude Code docs for connecting to PostgreSQL via MCP.
Token Efficiency
DBHub loads just 2 tools by default at 1.4k tokens — 13-14x fewer than alternatives — keeping the context window open for your actual work.
| MCP Server | Default Config | Default Tools |
|---|---|---|
| DBHub | 1.4k | 2 (execute_sql, search_objects) |
| MCP Toolbox | 19.0k | 28 |
| Supabase MCP | 19.3k | all |
Use Cases
- Local Development: Schema exploration, query validation, and data debugging with Claude Code, VS Code, Cursor, etc.
- Non-Technical Access: Expose curated, read-only views to non-technical staff via Claude Desktop, VS Code, Cursor, etc.
- Multi-Database Consolidation: Replace separate MCP servers for each database with a single DBHub process
- Production Troubleshooting: Read-only diagnostics with guardrails against runaway queries
Supported Databases
PostgreSQL, MySQL, SQL Server, MariaDB, Oracle, and SQLite.
MCP Tools
DBHub implements MCP tools for database operations:
- execute_sql: Execute SQL queries with transaction support and safety controls
- search_objects: Search and explore database schemas, tables, columns, indexes, and procedures with progressive disclosure
- explain_sql (opt-in): Show a query's execution plan without running it
- health_check (opt-in): Report connection pool state and buffer cache hit ratio
- Custom Tools: Define reusable, parameterized SQL operations in your
dbhub.tomlconfiguration file
Workbench
DBHub includes a built-in web interface for interacting with your database tools. It provides a visual way to execute queries, run custom tools, and view request traces without requiring an MCP client.
Installation
npx @bytebase/dbhub@latest --transport http --port 8080 --dsn "postgres://user:password@localhost:5432/dbname?sslmode=disable"
Also available as:
- Docker image
- MCP Bundle (one-click install, read-only)
- Claude Code plugin
See the Installation Guide for all options, Command-Line Options for parameters, and Multi-Database Configuration for connecting several databases at once.
Development
Requires Node.js >= 22.5.0 (DBHub uses the built-in node:sqlite module).
# Install dependencies
pnpm install
# Run in development mode
pnpm dev
# Build and run for production
pnpm build && pnpm start --transport stdio --dsn "postgres://user:password@localhost:5432/dbname"

DBHub MCP 질문
DBHub MCP를 Claude Code에 추가하려면 어떻게 하나요?
터미널에서 claude mcp add --env DB_PASSWORD=<YOUR_DB_PASSWORD> --env DSN=<YOUR_DSN> --env SSH_PASSPHRASE=<YOUR_SSH_PASSPHRASE> --env SSH_PASSWORD=<YOUR_SSH_PASSWORD> dbhub -- npx -y @bytebase/dbhub를 실행합니다. 모든 프로젝트에서 사용할 수 있게 하려면 --scope user를 추가합니다.
DBHub MCP를 Cursor에 추가하려면 어떻게 하나요?
~/.cursor/mcp.json를 열고 mcpServers 아래에 서버를 추가합니다. 위 설치 섹션에 표시된 Cursor 구성을 사용합니다.

DBHub connects to PostgreSQL, MySQL, SQL Server, MariaDB, Oracle, and SQLite through a single interface.
What MCP tools does DBHub provide?
By default it loads two tools, execute_sql and search_objects, with opt-in explain_sql, health_check, and custom tools.
Can DBHub connect to multiple databases at once?
Yes, multi-connection is supported through TOML configuration.
Does DBHub have read-only safety controls?
Yes, it offers read-only mode, row limiting, and query timeouts to prevent runaway operations.
How do I run DBHub?
You can start it with npx using the HTTP transport, and it is also available as a Docker image, MCP Bundle, and Claude Code plugin.
