Which integrations are available for this server?

Provides [Docker](/mcp/servers/integrations/docker) container deployment options for running the DBHub server with configurable database connections and transport options. Supports connecting to [DuckDB](/mcp/servers/integrations/duckdb) databases to explore tables, access schema information, and perform read-only SQL queries with safety measures. Provides access to [MySQL](/mcp/servers/integrations/mysql) databases for browsing tables, viewing schema information, and executing read-only SQL queries with safety protections. Allows querying [PostgreSQL](/mcp/servers/integrations/postgresql) databases, browsing tables, viewing schema information, and running read-only SQL queries with safety checks. Enables connection to [SQLite](/mcp/servers/integrations/sqlite) databases to browse available tables, view schema information, and run protected read-only SQL queries.

DBHub is a Minimal Database MCP Server implementing the Model Context Protocol (MCP) server interface. This lightweight gateway allows MCP-compatible clients to connect to and explore different databases:

Token Efficient: Just two general MCP tools (execute_sql, search_objects) to minimize context window usage, plus support for custom tools
Multi-Database: Single interface for PostgreSQL, MySQL, MariaDB, SQL Server, and SQLite
Secure Access: Read-only mode, SSH tunneling, and SSL/TLS encryption support
Multiple Connections: Connect to multiple databases simultaneously with TOML configuration
Production-Ready: Row limiting, lock timeout control, and connection pooling

Supported Databases

PostgreSQL, MySQL, SQL Server, MariaDB, 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
Custom Tools: Define reusable, parameterized SQL operations in your dbhub.toml configuration file

Installation

See the full Installation Guide for detailed instructions.

Quick Start

Docker:

docker run --rm --init \ --name dbhub \ --publish 8080:8080 \ bytebase/dbhub \ --transport http \ --port 8080 \ --dsn "postgres://user:password@localhost:5432/dbname?sslmode=disable"

NPM:

npx @bytebase/dbhub@latest --transport http --port 8080 --dsn "postgres://user:password@localhost:5432/dbname?sslmode=disable"

Demo Mode:

npx @bytebase/dbhub@latest --transport http --port 8080 --demo

See Server Options for all available parameters.

Multi-Database Setup

Connect to multiple databases simultaneously using TOML configuration files. Perfect for managing production, staging, and development databases from a single DBHub instance.

See Multi-Database Configuration for complete setup instructions.

Development

# 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"
