I open sourced a project I have been building on the side: a Go MCP server that connects Claude Code (or Cursor) directly to a live PostgreSQL database.

Repo: github.com/gupta-akshay/postgres-mcp

The problem it solves

Most "AI plus database" workflows still look like this: copy SQL out of a chat window, paste it into a DB client, run it, copy the output back. It breaks flow, and the assistant never sees your actual schema, so it guesses.

MCP fixes the connection problem. This server is what sits on the other end for Postgres.
