This isn't just a fancy chat interface. It's a command center where a Mistral-powered AI agent connects to my PostgreSQL data (via Postgres MCP) and gives me instant health reports and executable optimization commands.
Here’s the stack and how it works:
The Brain: I'm using an open-source Mistral model. Its reasoning capability is key—it doesn't just fetch data; it understands the intent behind a request like "Why is the database slow?"
The Bridge: The agent accesses the database through a 'Postgres MCP' (Monitoring and Control Plane) bridge, all running in Docker. This gives the AI secure access to the necessary metrics and logs without direct, risky DB exposure.
The "Wisdom": The system combines traditional DBA knowledge (like analyzing pg_stat_statements outputs) with the speed of AI.
The result? I no longer spend hours manually parsing query stats. I can just ask:
"Find the top 5 slowest queries from the last 24 hours."
"What's the index hit rate on the users table?"
"Simulate a new index on orders(customer_id). "
For that last part, it even uses hypopg to simulate index recommendations in seconds without locking tables.
I've essentially created a "turnkey" system that takes my natural language commands, diagnoses performance issues, and suggests concrete optimizations. It feels like a real example of how AI agents will merge with deep technical domains.
Happy to answer any questions about the setup.
