PostgreSQL MCP server

This is a small helper that connects your AI assistant to a PostgreSQL database. PostgreSQL is a common place where apps store their data, and this helper lets your AI read from it and answer questions about what is inside. It is handy for anyone who works with data but does not want to write SQL by hand.

What this MCP server does

You ask your AI a question about your data, like how many customers signed up last month. The AI uses this helper to send a read-only query to your PostgreSQL database. The helper runs the query and sends the rows back. Your AI then reads those rows and explains the answer to you in plain words. By default it can only read, not change anything.

What you can do with it

• List all the schemas and tables in your database
• Show you the columns and types of a specific table
• Run read-only queries and summarize the results
• Answer questions about your data without you writing SQL
• Count rows, find records, and spot trends
• Write changes like inserts or updates, only if you turn that on

Try asking your AI

• “List all the tables in my database”
• “Show me the structure of the users table”
• “How many orders were placed last week?”
• “Find the five most recent signups and show me their emails”

What it gives back to you

It gives back rows of data as a compact list, plus a count of how many rows came back. If the result is very large, it trims it and tells you it was trimmed, so you can ask for a smaller slice. Your AI then turns that into a normal answer in the chat, like a summary or a short table.

Before you start

Who it's for

Anyone who works with a PostgreSQL database and wants to ask questions about the data without writing SQL, like analysts, support staff, or product managers.
