I gave Claude direct access to my PostgreSQL database. Here's what happened.

I expected it to be janky. It wasn't. Three weeks ago I connected our production PostgreSQL database to Claude via MCP. No custom code, no ETL pipeline, no middleware - just a connection string and a few minutes of setup. What I can do now that I couldn't before: Before: "Hey, can someone pull churn by cohort for Q1?" → 2 days wait After: "What's our churn by cohort for Q1?" → 8 seconds Before: Scheduled weekly reports no one reads After: On-demand answers from anyone who needs them The skeptic in me expected hallucinations, wrong queries, broken joins.
