> If you need an enterprise-level database MCP server with built-in guardrails like approval flow, access control, data masking, and audit logging beyond what DBHub offers, check out Bytebase.
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.toml configuration file
