How to choose

• Start with the official server for the database you already run (Supabase, Neon, MongoDB, Redis, ClickHouse and others publish their own), then look at multi-database servers like MCP Toolbox for Databases or DBHub if you need several engines.
• Give the agent a read-only database user or a branch/staging copy first. Several of these servers can run writes and migrations.
• Check what the server exposes: plain SQL execution, schema browsing, or admin actions such as creating projects and branches.
• Only connect servers you trust: an MCP server can read and act on whatever its credentials allow.
