2026-08-20. Each fact on this page links to the sources used to verify it.
DBHub is Bytebase's universal database MCP server. It fronts PostgreSQL,
MySQL, SQL Server, MariaDB, and SQLite behind one MCP interface, run
locally via npx @bytebase/dbhub with a connection DSN. It has a
read-only mode, which the 1.1.0 release hardened by blocking
SELECT-invocable escape-hatch functions, and a 1.2.0 release added
bearer-token authentication for its HTTP transport alongside
per-statement result sets.
Authority rests on the bytebase organization (site bytebase.com) hosting
the repository, whose homepage is the product site dbhub.ai. The server
is built on the @modelcontextprotocol v2 SDK packages, though that is
not evidence of which revision it implements. No release note or README
statement names a supported specification revision, so spec_status is
unknown.
