PostgreSQL MCP server

This is a small helper program that connects your AI assistant to a PostgreSQL database. PostgreSQL is a popular place where companies keep their data, like orders, customers, or products. If you have one of those databases and want to ask questions about it without writing any code, this is for you.

What this MCP server does

You type a question in plain English, like who are my top customers. Your AI sends that question to this helper program. The helper turns your question into a database query, runs it against your PostgreSQL database, and sends the results back. Your AI then shows you the answer in the chat, as a table, a list, or a short summary. It only reads data, it never changes or deletes anything.

What you can do with it

• Ask questions about your data in plain English
• Search for a word or name across all text columns
• Get results as a table, JSON, or CSV file
• Handle large result sets without freezing
• Look up tables, counts, and totals in your database
• Run several questions in a row

Try asking your AI

• “What tables do I have in this database?”
• “Who is the customer that has placed the most orders?”
• “How many orders were placed today?”
• “Search for john in all text fields”

What it gives back to you

You get the answer right in your chat. Depending on what you asked, that could be a table of rows, a single number, a short summary, or a CSV file you can download. If the AI writes a bad query, you get a friendly error message with a suggestion instead of a crash.
