About DBHub

DBHub from Bytebase is a zero-dependency MCP gateway that exposes just two tools by default, keeping context usage low, with opt-in extras. It connects to several databases at once through TOML configuration and adds guardrails: read-only mode, row limits and query timeouts, plus SSH tunnelling and TLS. A built-in workbench is included.

DBHub is an open-source project written primarily in TypeScript, with 3.6k stars on GitHub. It was last updated in September 2026.
