Common questions.
QueryBear currently supports PostgreSQL, MySQL, and SQLite. We're actively expanding to more databases — reach out if you need a specific one.
Your database credentials are encrypted at rest. Every query goes through a security layer with table allowlists, column-level privacy controls, and read-only enforcement. A full audit log tracks every query an agent runs.
No. You control exactly which tables and columns agents can see. QueryBear enforces read-only access by default, and your database credentials are never exposed to agents. We also have a desktop app coming soon — with it, database requests never leave your computer.
Any MCP-compatible client works out of the box — including Cursor, Claude Desktop, Claude Code, Windsurf, and ChatGPT. You just paste a single URL.
Absolutely. The Business plan supports team API key management so multiple agents and team members can share controlled access to the same databases. Admins get full RBAC controls to limit which tables, columns, and operations each team member or agent can access.
