dbhub

One skill across Postgres, MySQL, SQL Server, MariaDB and SQLite — and its actual job is forcing explore-before-query on real schemas.

Install

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

Start the DBHub MCP server first, then install the bundled Claude Code plugin from the repo (plugin/.claude-plugin/plugin.json).

Best for

Querying an unfamiliar production-shaped schema, where the agent guessing table and column names is the failure you are trying to prevent.

Not ideal for

Setups without MCP. It requires the DBHub MCP server plus a DSN, and it can execute SQL — so scope the connection to a read-only role unless writes are the point.

About this skill

Guide for querying databases through the DBHub MCP server. Use whenever you need to explore database schemas, inspect tables, or run SQL queries via DBHub tools (search_objects, execute_sql, and the opt-in explain_sql and health_check). Activates on any database query task, schema exploration, data retrieval, or SQL execution through MCP — even if the user just says "check the database" or "find me some data". Ensures the correct explore-first workflow instead of guessing table structures.
