The shortlist

Connect an AI agent to your database

An MCP server is the standard way to let an agent inspect schemas and run queries against a real database. The choice is mostly about which databases you run and how much the server should do beyond querying.

Before you commit

Start read-only and against a copy. A model with write access can run a statement you did not intend, so use DBHub's read-only mode or Postgres MCP Pro's restricted mode, point the server at a replica or development database, and never hand it credentials that can drop tables. If your data lives in Supabase or MongoDB, both vendors publish their own MCP servers, listed in the index.
