Connects Claude to seven database systems through a single interface: Databricks SQL, BigQuery, PostgreSQL, MySQL, MariaDB, SQL Server, and SQLite. Exposes two core MCP tools: execute_sql for running queries with read-only enforcement and row limits, and search_objects for browsing catalogs, schemas, tables, and columns. You can connect to multiple databases simultaneously via a TOML config file, which makes it useful when you need to query across different data sources in one conversation. Built on Bytebase's DBHub project. Supports SSH tunneling, SSL/TLS, and service account auth for BigQuery. The progressive schema disclosure is handy when you're exploring unfamiliar databases and don't want to dump entire schemas at once.
